Develop a small android application

Hi FLs, I am looking for a simple Android Application (which should be scalable to develop iOS in future) with a clean and sleek design as per latest standards. The app will have following features: 1. User Sign Up using First Name, Last Name, Mobile number, Email Address and Password - You have to verify email address on submit. 2. User login using email and password. There will be two modules in the app: 1. To upload Bills using real time camera. 2. Fuel Tracker - This will help user to track KM travelled using GPS. He will click on START, app will ask to enable location (if not active), GPS will fetch the start location/coordinates and track KM travelled until he clicks END. App Development: 1. You will first create the application design and workflow and share with me for approval. 2. You will start coding it. Note - Code should have proper comments for easy reference. Your Proposal: 1. It should start with "Bella Ciao". All other proposals will be rejected. 2. Share you previous work link. 3. Timeline to build the app. 4. Total Cost Note - This is the basic app and we will be updating it in future. Hence, you can expect a long term job. Good Luck! Thanks
