Quiero desarrollar una aplicación Android que permita al encargado de fábrica llevar el control diario del inventario. La app debe incluir: • Registro de productos: listado mayor donde ver el stock de los mismos • Actualización de stock via excel con lo que el operario va a poder hacer el chequeo visual. Si esta ok la mercaderia, no hace nada, si hay alguna incidencia, la reporta - clickea y pone cuanto stock esta viendo - o si no hay stock. • Mapeo del depósito: un sencillo esquema visual que indique en qué sector se encuentra cada mercadería. • Configuración de parámetros donde se pueda cargar los stocks: quiebre: entre tanto y tanto, bajo stock: entre tanto y tanto, medio stock: entre tanto y tanto, alto stock:...

I want a mobile app that lets me enter a complaint once, choose any contacts already stored in the app, and have that message automatically reach every selected number in one tap—SMS, WhatsApp, or another reliable channel you recommend. Key flow • Create complaint → select contacts → send automatically • App logs date-time and keeps a live counter of “pending days” for each open item until I mark it resolved • Simple list view with filters for open vs. closed complaints and a detail screen showing the running day count There’s no hard deadline, so you can prioritise a clean, maintainable code-base. I’m happy to discuss whether you build natively for Android or use a cross-platform framework such as Flutter or React Native; ...

My app is finished and archived in Xcode, the Apple Developer account is active, and every required asset—icons, screenshots, description copy, privacy policy link—is waiting in a tidy folder. All that remains is the actual submission to App Store Connect and shepherding it through Apple’s review until it appears in the store. Here’s the flow I expect: • Generate the production build with the correct signing certificates and provisioning profiles already sitting in my account. • Set up the App Store Connect record: pricing, territories, app privacy details, compliance questions (no in-app purchases). • Upload the build via Transporter or Xcode, spin up a quick TestFlight group so I can run a last internal test, then move it into “Ready fo...

I’m ready to move an idea from concept to fully-released mobile app and need an experienced developer who can deliver clean, production-ready builds for both Android (Google Play) and iOS (App Store). Here is what I have in mind: • One shared code-base (Flutter, React Native or similar) or two native builds—whichever you recommend for long-term maintainability. • End-to-end support, from initial architecture and UI implementation through testing, store submission and first-release monitoring. • Clear, well-commented source code handed over in a private repository, along with basic setup documentation so I can spin up the project locally. Acceptance will be based on: 1. Stable, crash-free installs on current Android and iOS versions. 2. Successful li...

I’m ready to bring a Google-Store-style shopping experience to iPhone and iPad users first, then scale further once the initial build proves solid. I need a developer who can take the concept from blank canvas to a fully functioning iOS app, guiding me through architecture, UI flow, and App Store submission. The core purpose and feature set are still flexible, so I’ll rely on your expertise to shape best-practice solutions for catalog display, checkout flow, and any integrations that will future-proof the codebase for a possible Android release later. Clean Swift or SwiftUI code, well-commented, and version-controlled in Git are must-haves. Deliverables • Complete Xcode project with readable, maintainable Swift/SwiftUI code • TestFlight-ready build plus assistan...

I need a reliable Flutter developer to give my existing mobile app a quick visual polish and clear out a few lingering bugs. The priority on the design side is refreshing our graphics: the main app icon as well as several background images need to be replaced with new assets I will supply. Please ensure they render crisply on every common device density and appear correctly in both Android launcher and in-app screens. Alongside the graphic swap, I’d like you to track down and solve the minor issues users have reported (occasional crashes on login and a misaligned toolbar on tablets). No new features are required—just clean, well-commented fixes that keep the current functionality intact. Deliverables • Updated app icon integrated into the build • All specified b...

I have a RecyclerView driven by a LinearLayoutManager. Card taps are currently picked up through an OnPress handler, and I already keep the underlying data in a ViewModel. The problem is simple: when a user opens a detail screen from any card and then presses the back button, the list always jumps back to the very top instead of revealing the card they originally tapped. I need the list to remember its exact scroll position so that returning feels seamless. You’re free to solve it however you feel is cleanest—saving and restoring the layout manager state, using the Navigation component’s back-stack handling, or any other proven method—as long as: • the previous scroll position is restored every time, • orientation changes don’t break the fi...

I’m looking for a developer who can build a clean, intuitive application devoted entirely to personal note-taking. My goal is a distraction-free space where I can quickly jot ideas, organise them in a logical structure, and retrieve them just as easily. Platform choice is flexible—desktop, mobile, or a web-based hybrid—so feel free to recommend the stack you think suits a personal workflow best. Key considerations • Speed and simplicity: the interface should load fast and stay out of the way while I write. • Local data ownership: notes must remain private, with any optional cloud element clearly explained and under my control. • Future-proof code: well-commented, modular, and easy for another developer (or me) to extend later. When you respond, show me ex...

I will send you the complete ChaloTrain source as a ZIP. Your first task is to open the project in Android Studio, iron out every build error and bug, and verify that the app name, icon, package ID and other Android-specific settings are correct. Once the code compiles cleanly I need both a release-signed APK and a Play-ready signed AAB. I have gone through Play Console once before, so I know the basics, but I’d like you to take the lead this time—create or update the listing, upload the bundle, handle content ratings, privacy policy links and any review feedback, and stay on the job until the status reads “Published”. Deliverables • Project configured and building without errors • Release-signed APK and AAB provided • App successfully uploa...

I’m at the very earliest stage of building a social-networking app that revolves around creative content sharing, specifically photos and short videos. Before any design or code starts, I need a solid concept document that clarifies what the product will be, why users will care, and how the core flow should work. Here’s what I expect from you: • A concise product vision that frames the app as a social network built for visual creators. • Detailed descriptions of the must-have screens and interactions for seamless photo/video posting, discovery, and engagement. • User personas, key use-cases, and an outline of the viral loops that keep people coming back. • Rough user-flow diagrams or low-fidelity wireframes (Figma, Sketch, or even Miro is fine) to il...

I’m building a language-learning app aimed at teenagers and I want its first release to feel as engaging and game-like as Duolingo. To get there, I need two things developed in parallel: • A complete English-learning curriculum broken down into XP-style skill trees, each packed with varied question types (multiple-choice, tap-match, type-what-you-hear, fill-in-the-blank, etc.). Every unit should clearly state its grammar or vocabulary target and come with enough graded questions to support spaced repetition. Deliver the content in a clean spreadsheet so I can import it directly into my CMS, along with a concise guide explaining the logic behind the difficulty curve and any media assets (audio snippets, sample sentences) you create. • A fresh, memorable app logo that speak...

My ecom iOS application is feature-complete and ready for release; all that’s missing is an Apple Developer Account to launch it. I will hand over the full Xcode project, app icon, screenshots, name, and any other required assets.

My iOS e-commerce application is fully developed, archived with Xcode and ready for App Store distribution. What I lack is an active Apple Developer account and access to App Store Connect, so I need a partner who already has that infrastructure in place and is comfortable submitting on behalf of a third-party project.

The build compiles cleanly for iOS 17 and below, uses only Apple-approved payment APIs, and has been verified against App Store Review Guidelines. What I need from you • Add me as an App Store Connect user (or handle the inputs yourself) so the build can ...

I’m looking for a straightforward app built on Emergent that lets our employees key data into a 14-column table, search or filter any of those fields on demand, and immediately view the results in an interactive dashboard. Here is what matters to me: • A clean, employee-friendly data-entry screen with validation for each of the 14 columns (I’ll supply the exact field names and rules once we start). • A query function—simple text or drop-down filters are fine—that can pull records instantly. • An interactive dashboard generated from the same dataset so staff can spot trends without exporting to Excel. You’re free to organise the underlying database as you see fit so long as every column remains searchable and the whole solution stays ...

I’m ready to bring a brand-new iOS application to life and need a developer who can guide the idea from concept through App Store launch.

At this stage I have the overall product vision and basic workflow sketched out, but I’m counting on you to help shape the technical architecture, recommend best-practice UI patterns, and flag any potential pitfalls before we dive into code.

I need a clear, actionable strategy for push notifications in my fashion shopping app. The focus is on NEW ARRIVALS alerts that fire the moment a user browses a specific category—no delays, the message must go out immediately.
