    I need a straightforward Android MVP that streamlines day-to-day PG / hostel operations. The single most crucial feature is a one-tap approval workflow so the owner can instantly accept or reject any tenant request. Around that, build: • QR-based forms for onboarding, offboarding and rent/payment submissions • A lightweight owner dashboard showing dues, cleared payments and tenant details in real time • Optional WhatsApp or SMS notifications, wired so they can be switched on later with minimal code changes The goal is proof of concept and speed of execution rather than extensive UI polish. Think of RentOk or SpaceBasic as reference points—but do not clone their flows. Preferred stack is native Android in Kotlin or Java, with Firebase (or any rapid back-end you t...

    I have an existing Flutter code-base that needs to be pared down to a fast, order-only experience. The goal is to let users scroll through products, pick quantities, and submit an order—nothing more. What has to change • Product list – Display just one item per row with its image stretched full width. – Place a “- 1 +” quantity selector and an “Add to Cart” button right on that row; no tap-through screens or pop-ups. – Scrolling must stay buttery-smooth even on long lists (no freezes, jank, or frame drops). • Login – Keep mobile-phone OTP verification only. Strip out social, e-mail, or any other methods. • Checkout flow – Eliminate all payment screens and gateways. After the cart, users simpl...

    I need an app for android and apple. The app is basically an agenda for my small forkforce of 10 people, with specific tasks for specific users with deadlines, notifications to user of pending tasks, notification to all when a user has completed his task, biweekly (every two weeks) agenda for the whole workforce. Two categories of users: administrator and common user Administrator has access to all the users, to assign or modify their tasks, send reminders and change the task priority to “regular” or “urgent”. The administrators setup the biweekly agenda, or modify it. The home page should have buttons for each user, when clicked, the users tasks should show up, in order of priority and date of creation of the task, with a color showing how close is the task to t...

    I have a Flutter app (currently Android-only) that is almost ready for release, but the sign-up screen throws “An internal error occurred [Configuration_Not_Found]” every time a new user registers. The Firebase project is already created, is in the codebase, and the API keys are in place. The only Firebase service I need right now is Authentication, with App Check switched on. I’m looking for someone who can trace the misconfiguration—whether it’s a missing SHA-1/256, an App Check setting, or a console rule—and get the authentication flow running smoothly. Acceptance criteria • A test build registers and logs in a new user without errors. • Firebase Authentication and App Check dashboards reflect the activity. • You give me a co...

    Ich plane eine neue Mobile App, die von Anfang an sowohl auf iOS als auch auf Android läuft. Das grobe Konzept steht – jetzt suche ich jemanden, der daraus eine funktionsfähige Anwendung macht und mich dabei Schritt für Schritt begleitet. Was mir wichtig ist • Native Performance mithilfe von Flutter, React Native oder einer vergleichbaren Cross-Platform-Technologie – ich bin hier offen für Empfehlungen , weil mir das gar nichts sagt; übernommen aus dem Template. Scheint wichtig zu sein. • Ein sauber strukturierter Code, der später leicht erweitert werden kann. • Klare Dokumentation: kurze Setup-Anleitung, Architektur-Übersicht und Hinweise zu Drittanbieter-Bibliotheken. • Regelmäßige Builds, damit ich den ...

    I have an ongoing project that has stalled and I need a fresh pair of expert hands to carry it over the finish line. All core requirements, partial assets, and existing documentation are ready for you—what’s missing is the execution to bring everything together, polish the rough edges, and ensure a smooth, on-time delivery. Here’s what I can share upfront: • Current status: key components are half-built; code and design files are organized in a private repository. • Scope flexibility: whether your strengths lie in web development, app development, or graphic design, I’m open to tailoring the remaining workload around your expertise. • Collaboration: we’ll work iteratively, with quick check-ins and milestone reviews to keep momentum high. You&r...

    I need a small iPhone app that takes a URL I enter and, the moment I launch it, starts reloading that page on its own. A simple text field (or saved preference) for the address and a slider or input for the refresh interval is all the interface I’m after. If it can keep running while the screen is on that’s perfect; background refresh is a plus but not essential. Notifications about each refresh or when the page actually changes would be nice to have, yet I’d like them to stay optional so I can toggle the feature off when I don’t need alerts. I haven’t decided whether to ship this to the App Store, so please build in a way that lets me choose later. A TestFlight or side-loadable build is fine for the first delivery, but I’d welcome your advice on the q...
