Mobile App Development is the creation and development of phones, tablets, personal digital assistants, and other devices that have operating systems. It involves creating software applications for the devices, such as games, utilities, and sometimes even simple to-do lists. These applications are created using programming languages such as HTML5 and JavaScript, which allow developers to create a good user interface. Mobile App Development requires both specific and hard skills from developers, from debugging existing applications to creating entirely new ones.

A great benefit of having a Mobile App Developer on your side is the knowledge and experience they can provide to make your business grow. In addition to creating mobile apps that are good for the user experience, Mobile App Developers can help you with backing up the data from your application securely, modifying an existing app to meet new requirements, troubleshooting any current issues in your application, setting up a server for your application and so much more.

    I need a straightforward way to pinpoint where a specific mobile number is during standard business hours. GPS tracking is the preferred method, and I only need periodic location updates rather than a constant real-time feed. The end goal is to improve our customer service workflow: when a caller rings in, I want to know the current area of the handset, the registered owner’s name, and the business name (Darren) so my team can respond accurately. Please outline the steps, tools or APIs you’ll use for GPS-based positioning, how frequently you can push those updates, and how you will present the data—map view, simple coordinates, or a brief report are all acceptable as long as it’s clear and reliable. If you’ve implemented similar tracking or geofencing solut...

    I need a very small Android application whose only job is to launch and immediately play a single MP4 video in full-screen. As soon as the user taps the app icon, the video should start on its own—no play, pause, seek bar, or any other controls visible.

Please package it inside the APK, so the app works offline with no additional downloads. Android Studio, Kotlin or Java, and the built-in VideoView or ExoPlayer are all fine as long as start-to-finish playback is seamless on Android 8.0 and above.

    My production Flutter app has begun to misbehave on Android 14, 15 and 16 preview builds. The root cause is obvious: the codebase is still on an older Flutter release and the underlying Android SDK has marched on. I need the entire project migrated to the latest stable Flutter version, compiled against the newest Android SDK, and thoroughly tested so it works smoothly on those three OS versions. The scope is simple but critical: upgrade the Flutter framework and all dependent packages, refactor any deprecated APIs, fix compile-time warnings, and resolve run-time crashes or layout glitches that appear only on the newer Android versions. Afterwards I expect a clean, reproducible build (Android App Bundle) plus a short changelog summarising what was updated and why. Deliverables • Up...

    I have an existing Android app that is stable but still very lean on features. The immediate goal is two-fold: first, roll out a new “upload” capability inside the app (users need to be able to select a file—primarily images or PDFs—from local storage and send it securely to our backend); second, compile, sign, and publish the updated build to the Google Play Console so the change is live for all users. The current stack is Kotlin with standard Android Jetpack libraries; the backend is ready and exposes a REST endpoint for the upload, so the mobile side only needs to handle file selection, progress indication, and a simple success/fail response.

The initial release needs three core modules developed from scratch: task management, calendar integration and note-taking. I’m open to your suggestions on extra workflow boosters, but these three must ship fully polished, tested and production-ready. Code quality, readable commits and automated unit/widget tests are non-negotiable. I already have backend APIs in place, so the work focuses on UI/UX, state handling, offline support and integrating the existing REST endpoints. You&...

    Necesito desarrollar una aplicación móvil disponible tanto en iOS como en Android. El corazón del proyecto es la integración con redes sociales: los usuarios deberán poder iniciar sesión con sus cuentas existentes, compartir contenido dentro de las principales plataformas (por ejemplo Facebook, Instagram o Twitter) y ver sus propios feeds o perfiles enlazados desde la app. Cuento con la idea general y algunos bocetos iniciales; requiero que conviertas esos conceptos en una aplicación funcional y estable. Aprecio sugerencias sobre el stack más eficiente (Swift + Kotlin nativos, Flutter, React Native u otra alternativa multiplataforma) siempre que garantice buen rendimiento y una experiencia uniforme entre ambos sistemas operativos.

    I’m building an end-to-end lending experience for iOS that feels as smooth as Slice or Moneyview. The job covers both sides of the stack: a sleek native iOS front end and a secure, scalable back end with the APIs that power it. On the user side the flow is simple but must be rock-solid. A new customer signs up with email/password, can just as easily use a social account, and once inside can enable Face ID or Touch ID so returning is frictionless. They complete a loan application form, the system instantly checks eligibility, returns an approved amount (or declination), shows a clear repayment schedule, and later lets them review every past loan in a dedicated history screen. I need the full technical delivery: • iOS app (Swift or SwiftUI preferred) that implements the entire j...

    Quiero trasladar mi página de inventario a una app Android nativa que trabaje exactamente con la misma base de datos: ni copias, ni sincronizaciones externas, sino conexión directa para que todo cambio se refleje al instante entre web y móvil. El usuario ya ingresa en la web con su correo y contraseña, así que el flujo de autenticación debe mantenerse idéntico en la aplicación. Necesito que la app reproduzca las funciones que hoy ofrece el sitio —gestión de productos, movimientos de stock, reportes y cualquier otra vista crítica— con la misma lógica de negocio y sin perder velocidad. Si en el proceso puedes añadir notificaciones en tiempo real o mejoras de usabilidad, serán bien recibi...

    Android Task Management App

    Cont confirmat

    I need a clean, native Android application that works as a focused productivity tool centred solely on task management. The core flow is simple: users create tasks, edit them, mark them complete, and view an always-updated list of what still needs attention. Fast load times, smooth transitions and a clutter-free Material-compliant UI matter more to me than a long feature checklist. Key features and behaviours • Add, edit, archive and delete tasks locally (Room or Realm preferred, but I’m open if you can justify another lightweight on-device store). • Optional grouping or tag system so users can sort their list quickly. • Swipe or long-press gestures for common actions. • Due-date picker with basic notifications. Push is not required at launch; local ale...

    I have already wrapped up all product design, UX, and UI work for my new Android app and now I need the engineering muscle to bring it to life. Your main mission is two-fold: first, build system-level battery-optimization enforcement so the app behaves responsibly in the background without being killed by Doze or aggressive OEM policies; second, hook the project into Firebase. On the Firebase side, the app must support Authentication and Realtime Database right out of the gate, with Cloud Messaging for push notifications and Remote Config for on-the-fly feature tuning. For sign-in flows, I only need email-and-password and Google Sign-In. You will be working from a clean, well-commented repository that already contains the complete UI layer. I’ll provide the Figma files, current Gra...

    I am looking to build a custom SaaS web application that works smoothly on desktop and Android devices (mobile browsers). The website is only a functional reference for user flow and features. Design, code, branding, and content must be completely original. This is NOT a clone. The system must be built in a flexible and modular way, so that in the future I can change the business model (for example, shifting from Android services to selling digital products or gift cards) without rebuilding the platform from scratch. ⸻ PLATFORM REQUIREMENTS • Fully functional on desktop browsers • Fully responsive and optimized for Android mobile browsers • Clean UI/UX suitable for future mobile app integration • Scalable architecture (No native Android app required at this st...

    Driver App with Waze Integration -- 4

    Cont confirmat

    I am building a React Native or Flutter driver application—think Uber’s driver app, but with no payment or passenger-matching logic. The core requirement is a smooth integration with Waze for turn-by-turn navigation, wrapped inside a secure, professional-grade driver experience. The scope in a nutshell • Account & authentication: drivers create a profile that they can unlock via Face ID, password or fingerprint. During first-time setup the Face ID photo must be matched against the photo on the driver’s license (you may rely on any reliable on-device comparison API or a lightweight server call—open to your recommendation). • Daily workflow: once logged in, the driver starts a “shift”, completes a short pre-trip vehicle checklist, licens...

    I have mapped out a new productivity-focused mobile app and now need a UI/UX specialist to turn my sketches and user stories into a polished, intuitive experience. The scope is end-to-end: establishing the visual language, defining smooth user flows, and delivering a clickable prototype that I can pass straight to developers. The ideal match is someone who lives in Figma, Sketch, or Adobe XD and can back up their approach with solid human-centred design rationale. When you apply, please link to past mobile projects that best highlight your process—from wireframes through high-fidelity screens—so I can see how you translate complex workflows into clean, engaging interfaces. Core deliverables: • Low- and high-fidelity wireframes for each key screen • A cohesive UI k...
