Need help creating a mobile app from scratch that will take over an entire market. I have no experience but I've been working with Codex and such to give myself a MVP is you want to call it that. The app must be user-friendly, scalable, and innovative, with a strong focus on user engagement and retention. I am looking for a developer who can guide me through the process and ensure the app meets high standards, has the ability to update it whenever I get a business on and honestly help me like a co founder. If you're willing to be that important of a role.

Hello Upwork Developers! This app will be a critical tool once it's finalized. Looking for an experienced, supportive, and communicative developer in the Sacramento or San Francisco Bay area.

Notifications (Optional) Email notifications Push notifications (if determined needed; nice to have) In‑app alerts Push notifications require: Firebase setup Apple/Google certificates 8.

Maintainability Requirements The app must be built so I can: -Add fields -Edit forms -Add pages -Update logic -Manage Supabase -Publish updates -Debug issues This is why FlutterFlow and post-app training is essential, so I can reliably handle the maintenance aspect of taking over control.

Seeking an experienced mobile app developer to create a fully functional MVP that combines social features with an AI chat component. The app should be clean, stable, scalable, and ready for early user adoption, not just a clickable demo. Specific details about the app’s concept and logic will be shared under NDA. This project has a clear roadmap and strong vision for launch, and we’re looking for a thoughtful, skilled developer who can help architect and build a production-ready product with strong user experience, reliability, and performance. Complete UI/UX designs and flows have already been created in Figma, so this role is focused primarily on development, backend architecture, integrations, and implementation rather than design. Preference will be given to developers located in the DC, Maryland, or Virginia (DMV) area for easier collaboration and communication throughout the project, and occasional in-person meetings if needed. Deliverables & Requirements • Develop a cross-platform mobile app using Flutter or React Native • Build secure user authentication, profiles, friend systems, and group chat functionality • Integrate AI chat features via API with moderation and safeguard controls to prevent misuse • Implement reliable push notifications and time-sensitive user interactions across iOS • Set up scalable backend architecture and database infrastructure • Translate existing Figma designs into a polished, responsive mobile application • Conduct testing, debugging, and QA to ensure app stability and performance • Experience with Firebase, Supabase, WebSockets, or similar real-time technologies preferred • Deliver a functional app ready for deployment to the App Store

4 WATCHES MOBILE APP CONCEPT AND FUNCTIONS: I created a 14 year calendar that begins on September 23, 2017 and ends on September 23, 2031. The calendar is linked to a clock that's equally divided into four equal sections. Each of the 4 sections represents 1,260 days. The movement of the clock is clockwise, and it begins at the 6PM position. Each of the four sections is divided into 12 sub-sections called "houses." Each of the 12 houses represents 105 days. I have a very rough draft of the app cover page. There will be 8 or 9 tabs total. A "blinking" red block advances clockwise every 105 days to highlight the current position of the 48 houses. MOBILE APP TABS: TAB #1/HOME CURRENT 4 WATCHES "CLOCK" POSITION. Also Shows Current Date, Current "Watch", Current "House" & Current Time of Day. TAB #2 ABOUT THE FOUR WATCHES OF THE NIGHT TAB #3 DAILY CALENDAR: This is an actual functioning calendar app. Users are encouraged to post significant news events that occurred each day; TAB #4 14 YEAR CALENDAR. This tab breaks out to a list of 14 sub-tabs for the years 2017 thru 2031. These 14 sub-tabs break out to 12 more sub-tabs for each month of the corresponding year. This calendar can be edited by the user. TAB # 5 LIST OF THE 48 HOUSE NUMBERS AND THEIR DATES. This tab simply shows a list of the 48 Houses and their dates. For example: #1 September 23, 2017 - January 5, 2018 #2 January 6, 2018 - April 20, 2018 TAB #6 TO BE DETERMINED... TAB #7 Jump To House [1 to 48] This page allows users to enter numbers 1 through 48 to view the 105 day span of each "house" set against the calendar year. TAB #8 Jump To Any of the 5040 days [1 to 5040]. This page allows users to enter a number from 1 to 5040, to jump to that particular calendar day within the 14 year calendar. TAB #9 MERCH/SHOPPING

We have a substantially built, test-covered React Native (Expo) + Supabase mobile app. This is NOT a greenfield build. The core is done, including a solid architecture and a good test suite. We need a developer to enhance the app, focusing on performance, reliability, and user experience. The ideal candidate will have experience with React Native and Supabase, and be able to work independently to deliver high-quality results.

I currently have a digital sticker app called, Pixel Parade App which is "supposed" to be available on iTunes and google play - it features in app purchases of various digital sticker collections. The current developers cannot service my app due to internal reasons I was told bandwidth issues. I have had nothing but problems with this development team for many years trying to get this app to the market place. I need someone that can maintain this app so it is available and working as well as update the app as needed with additional features in the future. I am a designer and not a coder - I believe the app was created with Flutter. I could be wrong.

I need a simple mobile app MVP built and published to iOS and Android. The app is a basic platform where users can sign up/login. One type of user creates an account, uploads photo (s) of the item being shipped and completes the purchase. Another type of user is the driver who picks up the orders. The driver will need back end access to view the route, order, order status, email, etc ( whatever is needed). Plain and simple. The goal is to keep version 1 simple and scalable. The app must be built using Flutter (single codebase for iOS and Android) and use Firebase for the backend (no custom backend). It should include basic features like user authentication, a dashboard, ability to post and browse items, accept items, and a simple profile page. Stripe or Square to process homeowner payments. Calendar or built-in booking to let homeowners request services. I also need help submitting the app to the Apple Itunes and Google Play. I’m looking for a developer who has experience with Flutter + Firebase and has published apps before.
