I want a lightweight Kotlin-based Android app that lets me test SMS delivery through our own workflow. The interface can stay basic and functional: a single screen for server settings and a task list, another for simple settings where I can type or paste the whitelisted numbers myself. Typical flow I have in mind • I key in the server’s IP and port. • The app calls my REST endpoint (Retrofit / OkHttp) and pulls any pending test messages. • Each task shows the destination number and the body text. • Tapping Send launches the system SMS composer with ACTION_SENDTO—no background sending at all. • When I come back, I tap Sent, Skipped, or Failed and the app pushes that status back through another REST call. Login is not strictly required, yet ...

I’ve just released a secure messaging app for individual users and I want to scale installs quickly through Google App campaigns. Because my own Google Ads account is still in the learning phase, I need the campaign to run from your well-established account so it benefits from your higher quality score and existing spend history. Your task is straightforward: create, launch, and optimise an App-Install campaign whose sole KPI is the lowest possible cost-per-install while maintaining download quality. All assets—logo, screenshots, promo text, Firebase SDK, and the Google Play link—are ready for you. Key points • App type: secure messaging (not gaming, e-commerce, or productivity) • Target audience: individual consumers who value privacy • Primary goal: max...

I need an Android TV application that lets me use my television as a full-screen security monitor for my ONVIF-compatible cameras. The core requirement is reliable discovery, pairing and display of multiple cameras with smooth switching between feeds. Beyond the live view, I also want the same interface to handle recorded content, so please integrate both live streaming and video-on-demand playback. If you prefer ExoPlayer, VLC SDK or another library that handles RTSP / HLS well, just tell me why—it only has to be stable and lightweight on Android TV. Functionality I expect: motion-responsive live view, optional PTZ controls where the camera supports it, and a simple grid/thumbnail view so I can jump to any camera instantly with the TV remote. A neat extra would be a timeline s...

I have an Android-only social media application that is ready for a thorough shake-down before the next release. I need fresh eyes to hunt for anything—from a misaligned icon to a performance hiccup—and document it clearly so my dev team can replicate and fix the problems fast. Scope of the test • User interface: check every screen, button, gesture, dark/light mode, and different screen sizes for layout breaks, visual glitches, and navigation dead-ends. • App performance: measure launch time, scrolling smoothness, memory/CPU usage, battery impact, and behaviour on weak networks (3G/Edge) or with background apps running.

I have an already made Android-ready Godot project, “FlappyBoat,” and it is time for the 1.1 update release. The core gameplay is finished; what I need now is solid Facebook / Meta ad monetisation without disturbing the tight, fast-paced feel players already enjoy. Note : Don't place any low bidding amount for catch , just bid the exact charges , otherwise you'll be rejected. Scope • Integrate two to three Facebook Ads SDK packages. • Serve Banner Ads and Interstitial Ads. • Show them at the start of a run, after a game-over screen, and during level transitions. • Hand back a clean, well-commented Godot project plus an APK or AAB that I can drop into Google Play.

I have a concept for a standalone utility app that will run exclusively on Android, and I need a full-stack developer who can take it from idea to Play-Store-ready release. The job covers everything: designing the front-end interface users will interact with, building the back-end services the app calls on, and wiring the two together so the experience feels fast, stable, and intuitive. Because it is a utility tool, the core feature set is compact but performance-critical. I need clean, maintainable code (Kotlin or Java on the client is fine; the server side can be Node, Python, Go—whatever you’re most productive in as long as it is well-documented). You’ll set up the database, create any required APIs, implement basic analytics, and prepare a simple admin panel for conf...

I need a mobile application that turns everyday walking or running into a real-world incentive. The concept is strictly step-based: the phone’s pedometer records each stride, converts it into reward points, and lets users cash those points out for digital gift cards. Core workflow • Walking or running only—no cycling or general fitness modes in this release. • Reliable step tracking that resists spoofing and feeds a secure points ledger on the backend. • Points redemption through an in-app catalogue of gift cards (e.g., Amazon, Apple, major retailers) with automated code delivery. Admin requirements An internal dashboard should allow me to set step-to-point ratios, upload new gift-card SKUs, and view usage analytics. Deliverables 1. Native or c...

I’m handing over the full Android Studio project for my Java-based wallpaper app and need a developer who can jump straight into small-scale, UI-centred refinement. The core functionality—wallpaper loading, favourites, watermark, maintenance and force-update modes—already works; what I lack is the last layer of polish, stability and optimisation. The area where I need the most help is pure UI development and performance tuning. Expect to focus on tightening the RecyclerView experience, trimming any sluggish interactions and making sure everything feels smooth on a range of screen sizes. Key interface touch-ups I’d like delivered: • Navigation layout improvements • Visual design tweaks (no full redesign) • Responsive design adjustments Beyon...

I want to get an Amazon Appstore developer account fully opened, verified and ready for future releases, then have a simple non-game test app created and published so I can see the whole flow end to end. I do not yet have any code, so you’ll handle the lightweight build (a basic utility “hello world” is fine), package it as an APK/AAB that meets Amazon’s guidelines and walk me through each submission screen until the listing goes live. Key steps I expect: • Guided creation of the Amazon developer account, including any certificate, tax or policy sections. • Development of a minimal, clean test application suitable for public release (no gaming elements needed). • Store-compliant assets, screenshots and a short description so the app passes review. &b...

I need a complete ride-hailing ecosystem built from the ground up. The passenger app must work seamlessly on both iOS and Android, offering real-time geolocation, Razorpay/Paytm payment processing, and automatic fare calculation that factors in tolls, airport parking, border taxes, service tax, and our commission. On the driver side, an Android app should mirror the same map accuracy, display the live fare breakdown, and accept rides pushed either manually or through automatic dispatch logic. A web-based admin panel will give me full control over pricing rules, driver onboarding, fleet categories (hatchback, sedan, SUV), and promo codes, while a separate dispatcher console must allow staff to assign or reassign trips instantly. All data and media will sit on an AWS stack that you configur...

I already have the entire content strategy mapped out and polished UI/UX screens supplied as responsive HTML files. Now I need someone to transform those assets into a production-ready mobile application that runs smoothly on both iOS and Android. Scope • Translate the provided HTML designs into native or cross-platform code, preserving the “bite-sized, scrollable card” experience users will swipe through for various learning topics. • Build and wire up the complete backend: REST or GraphQL API layer, business logic, and database. I’m open to the stack you feel most comfortable owning—just make sure it’s scalable, smooth and maintainable. • Implement secure Email/Password login; the architecture should leave room for social • Stand ...

Create a subscription-based app for both Apple Store and Google Store and also get those apps uploaded to those stores. I have created an app using Base44 AI which I am happy with as far as the appearance and function. However, they don't have to tools to enable the subscription-based function. The app is very basic, I created an Excel worksheet that performs simple functions and the app is to present that data, along with ability of the user to input background information that the worksheet utilizes to make the calculations. It's essentially a tool that gives real estate beginners the ability to input variable info in order to determine if the property is a good deal. The app needs to be visually professional, easy to read/display, and also include a pdf download capability...

I want to build a full-featured telemedicine application that runs smoothly on iOS and Android smartphones, scales to tablets, and offers a companion web experience for desktop users. The core flow is straightforward: patients should be able to request a check up, get health metrics captured and automatically store in their profile. I will rely on you for both the mobile clients and the entire backend—including real-time video, encrypted messaging, user authentication, and a simple admin dashboard where clinicians can review session history and manage availability. A clean, modern UI, push notifications, and solid error handling are must-haves so the app feels polished from day one. Deliverables • Native or cross-platform iOS and Android builds ready for App Store & Play S...

I’m building an Android application that gives equal weight to fast, accurate order taking and reliable billing. On the front end I want a single, intuitive workflow: staff select items, totals calculate instantly, and a receipt can be issued or saved without bouncing between screens. Two user roles are essential from day one—Admin and Employee. Admin must be able to manage the entire catalogue, set prices or taxes, view every transaction in real time and pull daily reports. Employees only need the streamlined order-entry and payment screen plus a read-only view of their own sales history. If you can keep the architecture flexible enough to add a Cashier or Customer role later, that’s a bonus. Authentication should be simple and secure with email-and-password login. No ...

I need a compact Android app written in Java (Android Studio) that starts itself as soon as the phone boots, locks on to a high-accuracy GPS fix, and posts that latitude-longitude pair to my REST endpoint. The server’s JSON reply carries a single integer—how many minutes the app should wait before the next post—and the app must respect that interval for every subsequent transmission while the phone is on. Key behaviours • High-accuracy location only: use the fused-location provider with GPS priority. • Runs completely in the background, surviving task-kills and device reboots (JobScheduler / WorkManager or a foreground service with a silent notification—whichever meets current Play-services constraints). • If a fix is impossible, simply retry a...

I have a complete sample bubble-shooter APp and I need an experienced game developer to recreate it for Android, matching the gameplay, art style, and user flow one-to-one. The finished build must also run smoothly on current Android phones and tablets. The game is reward-based: players earn in-game currency as they clear stages.
