    I have a small, single-purpose accounting app that lets me record daily credit-debit entries. The current build was compiled years ago, so Android now blocks the installation outright on recent versions. My goal is simple: make the same APK install and run flawlessly on the latest Android release without losing any existing features or data formats. You will be working only with the APK package I provide; no original source code is available. That means the job will probably involve decompiling, updating the target/compile SDK level, handling any permission or file-storage changes introduced since Android 11, rebuilding, and signing the package again. Once installed, the app should still open its main ledger screen, allow new credit/debit entries, and save them exactly as before. Deliver...

    We are a nonprofit organization that connects volunteers with elderly and disabled homeowners who need help with lawn care. We operate on a "labor of love" model and are making a significant investment to automate our backend operations. We are looking for a Technical Project Manager + Developer (or a small, tight-knit agency) to build our new volunteer management web platform. We have an existing WordPress website that serves as our public-facing marketing and intake site, and an existing SQL database on our VPS that contains all our current volunteer, homeowner, and request data. We are building a custom mobile-responsive web application to handle the complex logistics of volunteering. Note on Infrastructure: We are NOT using Supabase. Our backend already exists—we have a...

    I’m an experienced C/C++ developer with a master’s in computer science who’s now shifting to Flutter. My goal is to become fully productive on both Android and iOS, with a special emphasis on getting UI and UX right. I learn fastest through hands-on work, so I’d like you to guide me while we build a small but complete app together. The core feature we will implement is OCR-based scanning that reads both vehicle VINs and driver’s-license data. I’m open to whichever route you recommend—Google ML Kit, Tesseract, commercial APIs, or even a custom model—as long as you show me how to wire it into Flutter cleanly and make the scanning flow feel native in both ecosystems. Here’s how I picture our collaboration: • You provide a well-stru...

    I’m putting together a small, close-knit team to bring a new Hospital Roleplay experience to life on Roblox. The project is still in concept-planning, so this is the moment where every idea can shape the final game. Co-Game Designer You’ll work shoulder-to-shoulder with me on storyline development—crafting the plot, writing engaging dialogue, and mapping out mission designs that keep players coming back. Expect plenty of brainstorming sessions and collaboration on the overall vision as we refine mechanics, pacing, and player progression. Lead Scripter If Lua is second nature, you’ll build the core systems that make the hospital feel alive: admission queues, patient AI behaviours, medical equipment interactions, and game-loop rewards.

    I need an end-to-end e-commerce solution built from scratch—a modern, responsive website paired with native-quality apps for both iOS and Android (I will need the final IPA and APK files ready for store submission).

    Hear Boost MP3 Opening Fix -- 2
    6 días left

    I have an MP3 that refuses to open inside the Hear Boost app on my mobile phone. The same track plays fine elsewhere, so the problem seems specific to the way the file and Hear Boost interact on Android/iOS. I need someone who can quickly pinpoint the cause—whether it’s a metadata glitch, codec or bitrate incompatibility, file-header corruption, or a quirk in the latest Hear Boost release—and get it playing normally in the app. A step-by-step explanation of what you did (or what I should do) to resolve the issue must be included so I can repeat the fix on other files if necessary. Please be ready to work with a test copy of the MP3 and share any small utility scripts, command-line options (ffmpeg, mutagen, etc.), or in-app settings changes you rely on. I’ll co...

    I need a polished mobile application released on both iOS and Android stores. At a minimum the build must include secure user authentication, reliable push-notification handling, and a clean flow for in-app purchases that passes Apple and Google review. I am open to the framework you prefer—whether that’s native Swift/Kotlin, React Native, Flutter, or another modern stack—as long as performance is solid and the UI matches the platform guidelines. I will provide branding assets; you will handle everything from architecture and coding through to submitting the binaries and guiding me through the store-listing steps.

    Flutter InDriver Source Code $16

    Verificado

    I need a fully working, ready-to-compile Flutter ride-hailing app that mirrors InDriver’s core flow. The driver and passenger features must already coexist inside the same codebase, and the project must build for both iOS and Android out of the box. I’m not commissioning new development—only share the complete source code you already have on hand. Essential deliverable: • Full Flutter project folder with driver and passenger modules included. Nice to have but not mandatory: • Brief setup notes so I can run flutter pub get, add my Firebase keys (or your placeholder back-end), and generate builds without extra paid plugins. If your code matches these points and is immediately available, send it over; otherwise, please do not bid.
