The ultimate guide to building a mobile app
Got a great idea for an app? Need a new way to grow your business? We tell you everything you need to know about building a mobile app in 2020.
Mobile App Development is the creation and development of phones, tablets, personal digital assistants, and other devices that have operating systems. It involves creating software applications for the devices, such as games, utilities, and sometimes even simple to-do lists. These applications are created using programming languages such as HTML5 and JavaScript, which allow developers to create a good user interface. Mobile App Development requires both specific and hard skills from developers, from debugging existing applications to creating entirely new ones.
A great benefit of having a Mobile App Developer on your side is the knowledge and experience they can provide to make your business grow. In addition to creating mobile apps that are good for the user experience, Mobile App Developers can help you with backing up the data from your application securely, modifying an existing app to meet new requirements, troubleshooting any current issues in your application, setting up a server for your application and so much more.

Quiero convertir la gestión de clientes de mi negocio en un flujo totalmente automatizado. La idea inicial es construir una app en Softr que permita: • Registro de clientes desde web o móvil. • Seguimiento de cada interacción que tengamos con ellos. • Apertura y control de incidencias para darles soporte. Toda la información debe guardarse en una tabla de Airtable que sirva como núcleo de datos y facilite la consulta en tiempo real.

Auditar app de lovable Tengo mi app Lovable casi lista, pero aún quedan varios detalles técnicos antes de publicarla. Busco a alguien que pueda cerrar este sprint y dejarla preparada para producción: 1. Conectar la API de la base de datos de artículos científicos que ya tengo seleccionada, mostrando los resultados dentro de la interfaz actual. 2. Configurar el plan de pago como prueba gratuita con opción de compra: el usuario disfruta X días sin costo y, al vencer, se activa el cobro recurrente que definamos. 3.

Programa de control de camiones • Seguimiento completo del vehículo: estado general, historial de mantenimiento y administración de rutas. • Monitoreo mediante reportes periódicos: me basta con recibir resúmenes automáticos (PDF, Excel o un dashboard web) cada cierto intervalo; el GPS en vivo no es imprescindible, aunque puede integrarse más adelante. • Panel web responsive donde pueda cargar, editar y consultar la información de cada camión, así como generar alertas de mantenimiento pendientes. &bull...

I want to get an Amazon Appstore developer account fully opened, verified and ready for future releases, then have a simple non-game test app created and published so I can see the whole flow end to end. I do not yet have any code, so you’ll handle the lightweight build (a basic utility “hello world” is fine), package it as an APK/AAB that meets Amazon’s guidelines and walk me through each submission screen until the listing goes live. Key steps I expect: • Guided creation of the Amazon developer account, including any certificate, tax or policy sections. • Development of a minimal, clean test application suitable for public release (no gaming elements needed). • Store-compliant assets, screenshots and a short description so the app passes review. &b...
I’m looking for a competent Android developer to turn my concept for a new utility app into a polished, Play-Store-ready product. The core goal is straightforward: create an intuitive tool that solves a specific everyday problem for users on Android devices. Here’s what I need: • Full Android app development—from initial architecture through to final APK and Play Store submission. • Clean, well-documented Kotlin or Java code (whichever you’re most comfortable with) stored in a Git repository I can access. • A lightweight, modern UI that follows Material Design guidelines and adapts gracefully across common phone and tablet sizes. • Basic analytics and crash-reporting integration (Firebase preferred) so I can monitor usage and stability after lau...

I’m building a Unity-based virtual surgery simulator in which a robotic arm reacts instantly to my hand movements captured through a standard webcam. MediaPipe must handle the tracking, while Unity (2022 LTS preferred) renders a fully 3D operating theatre that includes a human anatomy model showing detailed individual organs. Hand-gesture control is central, so the following gestures need explicit, low-latency mapping: • Open/close hand – grip or release instruments • Pointing – select targets or modes • Thumbs up/down – confirm or cancel actions • “Surgery” gesture – reserved for an additional context-switch you may propose The simulator should let the user perform these core procedures: • Incisions • Sutu...
I have an existing React web application and a Capacitor-wrapped mobile build called “My Magic Pencil.” It teaches by drawing live illustrations while it explains concepts, and I now need three tight upgrades: First, I want the iOS version shipped to the App Store. That means configuring the Capacitor project for Apple compliance, integrating in-app purchase for the subscription tier, setting up App Store Connect metadata, and guiding it through TestFlight review until approval. Second, the current interface feels rough. Start by manually walking through every feature on the website (this is the priority platform) and correcting any mis-aligned components, sluggish buttons, or visual glitches. Once the web version is spotless, repeat the same hands-on testing and polish for A...

I need someone who can sit with me this afternoon and again tomorrow afternoon in Daman or Vapi and help knock out a very simple Excel task. The file contains mixed data that just has to be copied and pasted into the right spots, then given a quick tidy-up. After a five-minute walkthrough I’ll provide, your job is to: • enter the records exactly where shown, • use basic formatting only—mainly data sorting, filtering, and a couple of straightforward formulas to keep totals correct. No macros, no complex analytics—just clean, accurate entry and a neatly organised sheet by the end of each half-day. Bring a solid grasp of Excel shortcuts, show up on-site for both sessions, and we’re good to go.

I need a cross-platform Flutter application that runs smoothly on both iOS and Android. The core of the project is a full-featured e-commerce experience built from the ground up. Key functionality required: • Product catalog with search and category filters • Shopping cart that updates quantities and totals in real time • Secure payment gateway integration (Stripe or similar) UI should follow current Material 3 guidelines, feel crisp, and load quickly even on older devices. State management with Provider or Riverpod is preferred, but I’m open to Bloc if you make a strong case. Clean, well-commented code and clear folder structure are essential because I will hand this to an in-house team for future updates. Acceptance criteria: 1. Both iOS and Android builds com...
I purchase complete projects from Codecanyon and need each one put into production quickly and cleanly. Your job is straightforward: • Deploy the admin panel exactly as the author documents—no deep code changes, just follow the guide, connect the database and point the domain. • Apply my colours, logo and other branding assets so the back-office and app reflect our identity. • Build the Android app from the same source, generate the signed AAB and publish it in my Google Play console. That flow will repeat for multiple projects every month, so I’m looking for someone who values speed, accuracy and clear communication. If you already work comfortably with typical Codecanyon stacks (Laravel / PHP, Flutter or React Native builds, Firebase push, etc.) you&r...
I am looking for an experienced mobile app/game developer or team to build a hybrid idle mining game combined with optional real cryptocurrency mining integration. PROJECT OVERVIEW: The app is inspired by games like Idle Miner Tycoon, but with optional real-world crypto earning features. The app should feel fun and addictive first, while also allowing users to contribute spare computing power safely and optionally. The platform should support: * idle/incremental gameplay * offline progression * optional background mining * hardware integration in the future * user accounts and cloud saves * crypto wallet functionality * monetization systems * upgrade systems and progression trees IMPORTANT: The app MUST prioritize device safety and transparency. Mining or CPU usage must never happen wi...
I run multiple sites (around 4–5 locations) where vehicles are regularly transporting material for different clients, and I want a simple system (website, or website + mobile app) to record, track, and report this data. 1. Trip / vehicle entry module For every vehicle trip, I need to enter and store the following fields: Site name (which of my 4–5 sites) Vehicle number Entry date Entry time Client name Material name (what material the vehicle is carrying) Permit quantity (total quantity allowed under permit for that client/vehicle) Actual quantity / units the vehicle is carrying (for example MT, CFT, etc.) Price per unit (rate of the material supplied to that client) Total sale amount for that trip (quantity × rate, preferably auto-calculated, but editable) A...

I need a complete ride-hailing ecosystem built from the ground up. The passenger app must work seamlessly on both iOS and Android, offering real-time geolocation, Razorpay/Paytm payment processing, and automatic fare calculation that factors in tolls, airport parking, border taxes, service tax, and our commission. On the driver side, an Android app should mirror the same map accuracy, display the live fare breakdown, and accept rides pushed either manually or through automatic dispatch logic. A web-based admin panel will give me full control over pricing rules, driver onboarding, fleet categories (hatchback, sedan, SUV), and promo codes, while a separate dispatcher console must allow staff to assign or reassign trips instantly. All data and media will sit on an AWS stack that you configur...
I’m prototyping a mobile serious-game that will ship on both iOS and Android, and the next milestone is all about animation. The character artwork is already designed, fully rigged, and waiting for you inside a Rive file (no design / no extra rigging required) What I need I have a list of 46 specific exercise moves and reference clips that blend strength and flexibility work. Your job is to translate each of those movements into a smooth, loop-ready animation on the existing rig. Every clip should feel natural and sit comfortably in the 2–6 second range so I can trigger them in-game without visual hitches. Deliverables • 46 individual .riv files (one per exercise) OR combined into one file with State Machine or Timelines • Ready to use via React Native to call ea...

I already have the entire content strategy mapped out and polished UI/UX screens supplied as responsive HTML files. Now I need someone to transform those assets into a production-ready mobile application that runs smoothly on both iOS and Android. Scope • Translate the provided HTML designs into native or cross-platform code, preserving the “bite-sized, scrollable card” experience users will swipe through for various learning topics. • Build and wire up the complete backend: REST or GraphQL API layer, business logic, and database. I’m open to the stack you feel most comfortable owning—just make sure it’s scalable, smooth and maintainable. • Implement secure Email/Password login; the architecture should leave room for social • Stand ...
Browser Reflex Clicker Game (MVP) Budget: Starting from $30 NZD | Timeline: 3–5 days | Scope: MVP only Overview I need a simple, browser-based reflex/clicker game. Think the Chrome dinosaur game — lightweight, instant to play, no install needed. One endless round that speeds up over time, 3 lives, game over when all lives are gone. This is an MVP — working and playable is the goal, not a polished product. What I Need (MVP Scope) Gameplay: Enemies move toward a fortress on screen. The player clicks/taps them before they reach it. Each enemy that gets through costs a life. Lose all 3 and the game ends. Enemy Spawning: Single enemy type only. Enemies spawn at a fixed rate that gradually increases over time. Some randomness in spawn position and timing is fine, but nothing...
I have a set of semi-realistic, AI-generated character sprites for my upcoming visual novel and I need each one resized to a very specific, custom resolution so they can be dropped straight into Unity with no extra tweaking. I already know the exact width and height in pixels and will share those dimensions as soon as we start. Beyond the precise resize, I’m looking for minor cleanup where needed—crisp edges, consistent transparency and colours locked to sRGB—so the images import cleanly as 2D sprites. If you’re used to Unity’s sprite-mode settings, pixels-per-unit values and tight packing, that experience will help everything slot in smoothly on my end. Acceptance criteria: • Every file matches the custom dimensions I provide. • Images open in...
I’m building a cross-platform mobile app whose main value is productivity through smarter commuting. The core of the product is a ride-sharing experience built specifically for carpooling. I need an experienced mobile developer (or small team) to take the idea from wireframes to a polished release on both the Apple App Store and Google Play. Here’s what I already know I want: • A clean, intuitive flow that lets users either offer or request a ride, match them in real time, and confirm seats. • Live GPS tracking so riders can follow the driver’s route and ETA. • Simple scheduling screens—think quick “create a ride” or “join a ride” actions that feel like a productivity tool rather than a taxi meter. • Secure sign-up and in...
Create a subscription-based app for both Apple Store and Google Store and also get those apps uploaded to those stores. I have created an app using Base44 AI which I am happy with as far as the appearance and function. However, they don't have to tools to enable the subscription-based function. The app is very basic, I created an Excel worksheet that performs simple functions and the app is to present that data, along with ability of the user to input background information that the worksheet utilizes to make the calculations. It's essentially a tool that gives real estate beginners the ability to input variable info in order to determine if the property is a good deal. The app needs to be visually professional, easy to read/display, and also include a pdf download capability...
I want to build a full-featured telemedicine application that runs smoothly on iOS and Android smartphones, scales to tablets, and offers a companion web experience for desktop users. The core flow is straightforward: patients should be able to request a check up, get health metrics captured and automatically store in their profile. I will rely on you for both the mobile clients and the entire backend—including real-time video, encrypted messaging, user authentication, and a simple admin dashboard where clinicians can review session history and manage availability. A clean, modern UI, push notifications, and solid error handling are must-haves so the app feels polished from day one. Deliverables • Native or cross-platform iOS and Android builds ready for App Store & Play S...
I’m building an Android application that gives equal weight to fast, accurate order taking and reliable billing. On the front end I want a single, intuitive workflow: staff select items, totals calculate instantly, and a receipt can be issued or saved without bouncing between screens. Two user roles are essential from day one—Admin and Employee. Admin must be able to manage the entire catalogue, set prices or taxes, view every transaction in real time and pull daily reports. Employees only need the streamlined order-entry and payment screen plus a read-only view of their own sales history. If you can keep the architecture flexible enough to add a Cashier or Customer role later, that’s a bonus. Authentication should be simple and secure with email-and-password login. No ...
I need a compact Android app written in Java (Android Studio) that starts itself as soon as the phone boots, locks on to a high-accuracy GPS fix, and posts that latitude-longitude pair to my REST endpoint. The server’s JSON reply carries a single integer—how many minutes the app should wait before the next post—and the app must respect that interval for every subsequent transmission while the phone is on. Key behaviours • High-accuracy location only: use the fused-location provider with GPS priority. • Runs completely in the background, surviving task-kills and device reboots (JobScheduler / WorkManager or a foreground service with a silent notification—whichever meets current Play-services constraints). • If a fix is impossible, simply retry a...
Looking for a freelancer to design and develop a 2D RPG fantasy mobile game. The project includes game design, coding, character creation, and overall development. Ideal skills include experience in mobile game development, 2D animation, and RPG mechanics.
I’m spinning up a large-scale event marketplace and need a full-stack engineer who’s already walked this road. The core build looks like this: • Robust user registration and profile system that relies on email sign-up first; social or phone options can follow later, so the architecture has to stay flexible. • Seamless payment processing with Stripe (credit/debit cards) and PayPal from day one, written so that adding crypto gateways later won’t require a rewrite. • Organizer-friendly event management tools—create, edit, publish, ticket tiers, capacity limits, analytics, the usual essentials—exposed through a clean dashboard and mirrored by solid APIs for mobile apps. I’m looking for production-ready code, clear documentation, and a pa...
Saya mencari pengembang aplikasi berpengalaman untuk membangun sebuah aplikasi Android bertema media sosial/jejaring sosial dari nol.

I need a brand-new IPTV application built from the ground up (this is not a simple re-skin). Phase one targets both Android phones/tablets and iOS devices; if things go smoothly we can later talk about Smart TV ports, but they are outside this brief. Core functionality I must see in the first public build: • Live streaming with minimal start-up latency • Full VOD / Series library support, including fast seek and resume • Accurate EPG that syncs seamlessly with live channels • Optional subtitles on both live and on-demand content - with option to link to online subtitles services • Multi-server capability so users can view multiple different source URLs without reinstalling the app or swapping server. • Token-based authentication for every request (no...
Every Monday our pull-requests pile up and I need a battle-tested iOS Tech Lead—someone who has spent at least a decade deep in both Swift and Objective-C—to give them a sharp, independent review. The scope is straightforward: open the Git repository, step through the outstanding PRs, and leave clear, actionable comments that raise our bar for code quality and standards, tighten performance, and surface any security weaknesses you detect. No mentoring sessions or team training are required; the goal is strictly to refine code, flag problems, and suggest solid fixes before we merge. Typical Monday workflow • Clone or pull the latest branch updates from Git • Review each PR line-by-line, checking architecture choices, memory management, threading, and API usage ...
I’m building a cross-platform matrimony service that feels fresh, colourful, and instantly intuitive. The platform must run seamlessly on the web and on today’s popular mobile devices while keeping every step of the journey— from sign-up to payment—simple, secure, and engaging. Authentication • Only phone number verification will be used, so the flow must include OTP generation, delivery, and reliable fallback handling. No email or social media sign-ups will appear in the UI. Core experience The heart of the service is smart matchmaking. I will need a robust profile-matching algorithm that can evolve; please come prepared to discuss the logic you suggest, the data points you’ll ingest, and how you will keep it both scalable and transparent to users....
