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.

Core concept — it's a metronome built specifically for dancers. Instead of just a click or beep, it speaks counts aloud ("1, 2, 3, 4") or calls out dance-specific cues ("Slow, Slow, Quick, Quick") timed to the beat. Think of it as a rhythm coach rather than a musician's tool. The main features planned: Metronome with voice counts — numerical ("1, 2, 3…") or ballroom-style ("Slow"/"Quick"), where a Slow = half note and Quick = quarter note Move builder — users can sequence counts together to define a named dance move (e.g. "Foxtrot Basic: Slow, Slow, Quick, Quick"), tag it by dance style (Salsa, Waltz, Tango, etc.), and save it for reuse Umbrella sequences — group moves together into a full routine (e.g. "Rumba Basic Sequence" = Basic Square + Underarm + Crossover) Training modules — Step, Rhythm, and Freestyle modules with progressive learning, including biomechanical reminders ("Shoulders down", "Butt tucked in") and footwork diagrams Audio file player — upload a music file, adjust its speed, loop sections, and layer in voice callouts over it Goal tracking — log classes attended, moves learned, social dances, performances, etc. User accounts — login, subscriptions (monthly or annual), demographic profile (dance style, level, lead/follow), and progress memory across sessions Multi-device — phone, tablet, laptop, and TV casting In short: it's a dance training app that wraps a smart metronome with voice coaching, move choreography tools, and progress tracking — aimed at dancers from beginner to pro level across Latin, Smooth, and other styles.

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.

We're a small US-based bread-baking app launching on Google Play. We need 12+ paid testers to install our app from a Closed Testing link, run through the core flow once, and stay opted-in for 14 days so we can satisfy Google's Personal Account testing requirement. WHAT YOU'LL DO (~30 minutes total) 1. Install our app on your Android phone via a Google Play Closed Testing link we provide. 2. Open the app, tap Library in the bottom bar, pick one of the 11 built-in starter recipes, and run it through the Plan flow (no typing required). Take a screenshot of the Plan result. 3. Run the Log flow: upload a photo of any real bread you have on hand (a finished bake, store-bought bread, a slice of toast, a bagel — anything bread-like), submit, then tap Share at the end and save the generated bake share card to your phone. 4. Optionally try the Check flow (take a quick photo of dough or any close-up object as a stand-in). 5. Submit a short written feedback note (what worked, what didn't, anything that broke or felt off) along with BOTH screenshots — the Plan result and the bake share card — attached to your Upwork reply. WHAT YOU'LL KEEP DOING (the 14-day part — this is the critical bit) Stay opted-in to the Closed Testing track for 14 days from your install date. You don't have to use the app during that window. You just have to not uninstall it and not opt out of the test. We can see opt-in status in our developer dashboard. PAYMENT $25 fixed-price, split: - $10 released after you submit your feedback note within 48 hours of being hired - $15 released at the 14-day mark, after we verify both required screenshots are attached to your reply AND you're still opted-in If you opt out, uninstall, or fail to attach both screenshots before 14 days, only the first $10 applies. WHO WE'RE LOOKING FOR - At least 50 completed Upwork jobs - 4.7+ star rating - Prior mobile app testing or QA testing experience preferred - Native or fluent English (feedback note is in English) - A personal Android phone running Android 10 or newer with a Google account WHO WE'RE NOT LOOKING FOR - iPhone-only testers — we need actual Android install behavior - Anyone who can't commit to the 14-day opt-in window HOW TO APPLY In your cover letter, please include: 1. Confirmation that you have a personal Android phone and a Google account ready to use 2. One sentence on the most recent mobile app you tested and what you found That's it. We'll hire fast — first 14 qualified applicants get the gig.

I need a React Native developer to help complete and stabilize my social media app, QueFlic, before QA and beta launch. This is not a full rebuild. The app is already built, but it needs missing flows completed, smoother user experience, error handling, and final pre-QA fixes. The app is a social media platform with photo posts, video posts, Live Photo posts, music/location/tag overlays, WordBox polls/Q&A/reactions, comments, messaging, and sharing. Main work needed: 1. Error management Add clear signup/login errors for username already taken, email already used, wrong password, failed login, and network errors. Add upload and post creation error messages. If upload fails, user should see a retry option. If publishing fails, app should not create ghost posts. Permission errors for camera, photos, location, and music should show clear messages instead of crashing or silently failing. 2. Landing pages / overlay destinations Create or complete a music/sound page where users can see posts using the same song or sound. Create or complete a location page where users can see posts tagged at the same location. Make tagged users open their profile. Make WordBox open the correct poll, Q&A, or reaction page. Each page needs clean back navigation. 3. Smooth post creation flow User should be able to upload media, edit, add overlays, preview, publish, and return to the feed/timeline. User should not get stuck in editing screens. New posts should appear correctly after publishing. Basic delete post option should work for the post owner. 4. Live Photo flow Smooth the Live Photo feature so users can add photos into a video timeline, preview the final Live Photo, pause/play, go back to edit, and publish without freezing or getting stuck. 5. QF logo / watermark playback controls Tap QF logo once to pause video or Live Photo. Tap QF logo again to resume/play. Double tap QF logo to restart the video or Live Photo from the beginning. 6. Basic social actions Delete post. Comment on posts. Message option if already built. Share post using the phone’s native share sheet so users can share to Instagram, TikTok, YouTube, text message, or copy link. I want this handled as a fixed-price, milestone-based sprint. First milestone should be a code/app review and written fix plan. After that, we can move into implementation. Budget is $1,000–$1,500 depending on what can realistically be completed. I am looking for someone experienced with React Native, Firebase, media uploads, social app flows, iOS/TestFlight, and Android/Google Play testing. No full upfront payment.
