I need a straightforward mobile app that runs natively on both iOS and Android and lets users start talking to one another the moment they tap a single, clearly labelled tab on the main screen. Once that tab is touched, the interface should reveal the people already using the app and open an instant-messaging view where two-way text chat flows in real time. Because this is for personal use rather than a commercial launch, the interface can stay clean and minimal—just the sign-in screens (email, Apple, or Google are fine), the central “Connect” tab, and the chat view with typing indicator, read receipts, and push notifications. A lightweight real-time backend such as Firebase, Supabase, or a similarly robust service would suit the project well; pick whichever you a...

I’m ready to bring a first-person role-playing adventure to Android and need an experienced mobile game developer to turn the concept into a fully playable title. The core idea is a story-driven RPG where players explore immersive 3D environments, engage in real-time combat, and level up through a classic skill-tree system. Here is what I’m looking for: • A complete Android build (Unity or Unreal Engine preferred) that runs smoothly on current mid-range devices. • Modular, well-documented source code so new quests, items, and locations can be plugged in without major refactoring. • Basic art assets and UI that showcase the gameplay loop—high-end visuals can follow in later phases, but the first milestone must feel polished and fun. ...

I’m ready to build a new mobile app that will launch simultaneously on Android and iOS. The concept itself is already mapped out, but I now need a developer who can turn that vision into a smooth, production-ready application and wire up in-app purchases from day one. Here’s what I’m looking for: • A single code-base approach (Flutter, React Native or similar) is fine, though I’m open to native Swift/Kotlin if you feel it will serve the long-term roadmap better. • Clean architecture, clear state management and readable, well-commented code. • Full integration of Google Play Billing and Apple’s StoreKit, including sandbox testing, receipt validation and graceful handling of purchase failures or cancellations. • App Store an...

I’m building a single shopping experience that runs seamlessly on Android, iOS and the web. The core stack is already chosen—Firebase for real-time data, authentication, cloud functions and Remote Config; Stripe for secure checkout; and DSers for automatic product sync and order fulfilment. Inside the app, shoppers need to browse a live catalogue, open rich product pages, add items to a cart, read and post reviews, then complete payment without ever feeling they left the experience. On top of that foundation I want a playful layer that keeps users engaged: a spin-the-wheel discount game, quick quiz challenges that unlock coupons, time-limited flash-deal races, and room for any fresh game concepts you can suggest. All content and promotions will be driven dynamically f...

Refactored code for speed, stability and maintainability 6. Deployment to the existing Play Store listing and post-launch support for bug fixes What I’d like to see in your bid: experience enhancing or scaling live Android apps with similar feature depth. A concise outline of how you would approach the upgrade will help me gauge fit, but lengthy formal proposals aren’t required at this stage. I will share the current codebase, API docs and full feature map once we agree on the collaboration....

I need an MVP Android application that lets patients view doctor profiles, pick an available slot, confirm the booking, and automatically receive a push or in-app reminder before their visit. The flow should stay friction-free, so skip any sign-up or social login screens; users land straight on the home screen and start searching. Core screens and behaviour • Doctor list with photo, specialty, and quick bio • Appointment calendar per doctor with real-time slot availability • Simple booking confirmation page and success screen • Local notification reminding the user of the upcoming appointment Design can stay minimal—native Material components are fine—but navigation must feel intuitive and responsive across current Android versions.

I have a headshot of myself that was taken with an old Android phone camera nearly 10 years ago, so it's very blurry and pixelated. I would like it updated and made clearer to represent today's professional photography standards and also some small details added, to certain areas, that weren't there before, but in an integrated and very photorealistic style that would give off the illusion that they were part of the original picture as opposed to causing a viewer to think that it was photoshopped. So, it would be the same image and background with more clarity and some modifications. I have more detailed descriptions already written out, a diagram, and visual references, because I've already had 3 different artists attempt to do this but either dropped the pro...

I need an internal mobile app that lets our field sales agents enter data the moment a deal happens and gives management an instant view of overall performance. The app must run natively on both iOS and Android so every agent, regardless of device, can work in the same environment. Core flow • Agents log in with company credentials, open a clean form, and record sales figures alongside essential client information. • Immediately after saving, those records sync to a central database and feed a live dashboard that management can open in a browser or on their own phones. • Agents can also open a personal performance screen to see their numbers in real time, helping them track progress without asking HQ for updates. Key functions for agents – Data entry (...

My mobile app is already live on both iOS and Android, and the next step is to boost high-quality user acquisition. The plan centers on two fronts: • Social media marketing across Facebook, Instagram and Twitter—organic content, smart paid campaigns and community engagement that convert impressions into installs. • Thorough app-store optimization for both Apple App Store and Google Play—keyword research, metadata rewrites, screenshot/video suggestions and review-response tactics that lift search visibility and ranking. Key results I want to see are a measurable jump in daily installs, lower cost per acquisition, and stronger category positioning. Please bring proven experience scaling apps in these channels, the ability to set up tracking links (Firebase, ...

I’m building an AI-driven security solution that watches live video feeds, decides in real time whether something needs my attention, and instantly pushes a mobile notification when it does. The heart of the job is the end-to-end pipeline: ingest the camera stream, run fast and reliable AI inference, and fan out alerts to my iOS and Android app with minimal delay. Every alert should arrive with a snapshot, timestamp, and location tag so I can act immediately from my phone. Low latency, high accuracy, and rock-solid reliability matter more to me than bleeding-edge experimentation. I’m happy for you to choose the framework—TensorFlow, PyTorch, OpenCV, or another stack—as long as the result is well-documented, container-friendly (Docker/Kubernetes welcome), and...

...and event-details pages suffer from overlapping elements, unreadable text, and images that refuse to size correctly. First, I’d like a rapid audit of the current CSS/JS so we can pinpoint exactly why the layout breaks. From there, I expect fixes that make the menus intuitive, align every element, scale the typography for easy reading, and keep visuals sharp and proportionate across iOS and Android devices.
