I need an iOS app that turns any LiDAR-enabled iPhone or iPad into a professional-grade foot scanner for custom bootmaking. The core of the job is a highly detailed 3-D capture that preserves every contour—bunions, hammertoes, callouses, blisters, overlapping toes, ingrown nails—so I can print an accurate STL file for each client.

Hi, You should have mac, xcode, iphone. I need to control your pc remotely.
I want to bring a fresh, well-designed iOS application from concept to App Store release. The core idea and feature set are still flexible, so I’ll rely on your guidance in shaping the technical architecture, UI flow, and overall user experience.

I need a single cross-platform trading application that can execute five distinct strategies covering algorithmic trading, high-frequency trading, and options trading.

I’m building a real-time live-streaming social app that runs smoothly on both iOS and Android. Viewers must be able to watch a host go live, type comments that appear instantly, send virtual gifts that trigger on-screen animations, and play with fun AR filters or effects while broadcasting. All users should be able to create an account with whichever method suits them—classic email/password, one-tap social login, or phone number verification—then switch devices without losing data. A straightforward profile page, text chat outside the stream, push notifications for when favourite hosts go live, and a simple in-app wallet for gifts are also part of the plan. While I’m flexible on the tech stack, I do expect: • Mobile builds for iOS and Android, approved for A...

I’m rolling out a web application with online payment capability and I need fresh eyes from Romania who can run focused functional tests on an iPhone. Here’s what I expect back: screen recording, plus a screenshot. I’ll provide a test account and tell you how to do it; you simply follow it, explore beyond it, and flag anything unexpected. Because regional factors such as language settings and local payment gateways matter, you must physically be in Romania and perform the test on an actual iPhone (no simulators). If that matches your setup, I’m ready to send credentials and get your first run scheduled immediately.
I need a fast turnaround on a set of up to ten lightweight Unity games for mobile. We will begin with one title and, once that is signed off, roll straight into the remaining nine. Reference: The core puzzle-solving mechanic stays, but everything the player sees or hears must feel brand-new. Think bright, cartoonish characters, playful animations, and a smoother overall flow. I will supply mood-boards and specific animation references so you can focus on execution rather than guessing the style. Scope of work • Code the entire game in Unity so it runs smoothly on both Android and iOS. • Produce all new 2D/3D assets, UI, and animations in a cohesive cartoon style. • Create or license light, upbeat SFX and music that fit the theme. • Integrate ads (AdMob or U...

Key requirements • Platforms: A single codebase that deploys to iOS and Android. Feel free to suggest Flutter, React Native, Kotlin Multiplatform, or any stack you’re comfortable proving production-ready. • Features: Effects and filters are the star of the show—think color LUTs, text overlays, glitch transitions, speed ramps, etc. No trimming, multi-track timelines, or audio studio complexity is needed for this first release. • UI: The interfa...
I need a seasoned mobile QA who can run a full round of tests on both my iOS and Android builds before the next release. The focus is three-fold: make sure every feature works as intended (functionality), verify the overall experience feels intuitive to a new user (usability), and push the app hard enough to surface bottlenecks, crashes, or memory leaks (performance). You will receive the latest TestFlight build for iOS and an APK for Android, along with a concise feature list and current known issues. After that, I want you to explore every screen, action, and edge case, document what you find, and back each issue with steps to reproduce, screenshots or screen recordings, and any relevant logs. Feel free to lean on tools such as Xcode, Android Studio, Firebase Crashlytics, Charles Proxy,...

I run a local e-commerce shop with its own mobile app and I’m ready to turn Instagram into our main growth engine. I need a marketer who lives and breathes the platform and can move quickly from strategy to execution.

I have an idea for a fast-paced third-person action title built specifically for iOS and Android. I’m looking for a developer who can take the concept from a rough design document all the way to a polished APK/IPA that passes store submission. Core mechanics will centre on short, intense combat encounters, fluid character movement and a progression loop that keeps players coming back. You will need to handle character control, enemy AI, level spawning, UI, basic VFX/SFX integration and in-app purchases. I expect a build that runs smoothly on mid-range devices without sacrificing visual flair, so optimisation experience for mobile GPUs is important. I’m open to Unity or Unreal—choose whichever engine you feel delivers the best performance for a third-person camera system,...

I want to recreate the Social App experience on both iOS and Android, keeping the focus tight on the two features my audience values most: rich user-generated reviews and an interactive map that lets them discover venues visually.

The build has to be fully bilingual (English plus the ability to drop in additional language files easily), so please structure strings for effortless localisation. Users must be able to sign up and log in with either classic email+password or their preferred social account; a lightweight onboarding flow is essential.
