I’m building an on-premise platform that runs physics-informed digital twins on high-performance, specialized Edge AI computers already installed throughout a commercial building. The goal is simple: reduce energy use while keeping occupants comfortable, all in real time. Here is what I need from you: • A complete autonomous control loop that ingests live sensor data, runs the digital twin locally and pushes commands back to HVAC and lighting subsystems. • Digital-twin models able to deliver all three key functions: ‑ Predictive maintenance ‑ Energy consumption analysis ‑ Environmental monitoring • Code written primarily in Differential Swift. If a low-level module truly benefits from C, C++ or Python, I’m open to mixed-language solutions, but S...

I'm looking for an experienced app developer to create an application for both iOS and Android platforms. The specifics regarding the type of app and key features are yet to be defined, so I'm open to suggestions and insights from experts in the field. Ideal skills and experience: - Proven expertise in developing cross-platform mobile applications. - Strong understanding of both iOS and Android design guidelines and best practices. - Experience with user authentication, in-app purchases, and push notifications. - Ability to provide insights on app type and essential features. - Excellent communication skills and a collaborative approach. Please share your portfolios and any relevant projects you've worked on.

I’m building a fresh social platform aimed squarely at teens and young adults and I need an experienced iOS developer to turn the concept into a polished Swift app. The core of the product is familiar social networking flow—create a profile, discover new people, share moments—but I want it to feel fast, modern and unmistakably native to iPhone. At this stage I’m keeping the initial feature set tight on purpose. The app must open with a smooth, secure user-authentication flow (email, Apple ID and ideally social log-ins). Once a user is in, the focus is on the timeline: post, like, comment, follow. Push notifications and in-app purchases can come later; right now I’d rather perfect the foundation for a young, trend-sensitive audience. I value clean, well-docum...

I’m ready to bring my concept to life as a dedicated iOS application, launching first on iPhone and iPad before we even think about any other platform. I’m looking for someone who can own the full build in Swift or SwiftUI, follow Apple’s Human Interface Guidelines, and keep the codebase scalable so a future Android or web version remains an option rather than a rewrite. After we sign an NDA I’ll share wireframes, a feature list, and REST-based API specs. Your role will cover architecture, clean UI implementation, secure data handling, push notifications, basic analytics, and a smooth App Store submission flow. Throughout the project I expect regular TestFlight builds so we can iterate quickly on feedback. Deliverables (all must be met): • Xcode project com...

I want to build (or license) an AI-driven workflow that can turn written concepts into finished, ready-to-stream TV-show style videos for my OTT platform. The core need is a system that can: • Accept a short brief or script and automatically create full-length episodic video content – visuals, voice-overs, music, basic edits and captions included. • Export in broadcast-ready resolution so the episodes slot straight into my OTT catalogue, while also letting me pull shorter cuts that suit social-media teaser posts. • Let me tweak pacing, voice style, branding graphics and end-slates without touching a traditional editing suite. I’m open to whichever combination of tools you prefer (Runway, Pika, Stable Video, Synthesia, custom Python, etc.) as long as you d...

I have a fully-developed Ionic / Capacitor project that compiles cleanly on the web. What I now need is your help taking that code all the way to App Store Connect. Here’s exactly what I expect you to do: 1. Fork or export the current repository to your own GitHub account, pull it locally, and run npm install so every dependency is identical to mine. 2. Add the iOS platform with npx cap add ios (if it isn’t already there) and keep it current by running npx cap update ios after each pull. 3. Produce a production build (npm run build) and follow it with npx cap sync so Capacitor copies everything into the iOS container. 4. Open ios/App/ in Xcode, sign in with the Apple Developer credentials I provide, and choose the correct development team. 5. Apply the specific signin...

I'm looking for a skilled mobile application developer to assist with the creation of an application focused on generating extra income. The app should primarily focus on: - User Profile Functionality: The app should allow users to create and manage their individual profiles. The user interface should be user-friendly and appealing. The ideal freelancer for this project should have previous experience in developing mobile applications with user profile functionalities. A portfolio of past projects related to income generation or finance apps would be an added advantage. I value great communication and commitment to quality. If you can deliver this with a clear strategy, I want to hear from you.

A customized app that will allow for one-on-one consulting between a person seeking advice from an expert that they can choose from based on the experts’ profiles. The session will use audio/visual or chat technologies. The app will enable the seeker to pre-purchase a 30-minute (maximum) session for a stated amount that will be charged against the seeker’s credit/debit card. The app must provide for the experts to show their “availability calendar” so that the seeker can choose the consulting session by day/time. The session will automatically terminate at the conclusion of the session timeframe.

I have a small MacOS-only project already packaged as a .zip. When the user opens it, two consecutive pages appear and the same button must be pressed on each page before the flow can continue. I want that step removed from the user journey: the button has to be clicked automatically, on both pages, without any extra input. The target is straightforward: • Detect the page load, • Locate the identical button (its selector/identifier is the same on both screens), • Fire the click event twice—once per page—so the process moves forward exactly as if the user had pressed “Continue”. Any approach that works natively on MacOS is acceptable—AppleScript, Swift with the Accessibility API, a lightweight shell/osascript wrapper, or an embedded automation ...

CalAI app we need a cloone that runs smoothly on both iOS and Android All features must be made. so to get no confusions ALL features are needed! The core experience must feel just as effortless: a user points the camera at a plate, snaps a picture, or scans a barcode, or simply types a quick meal description and—within moments—sees an accurate calorie count plus full macro and micronutrient breakdown.

We're looking for someone who has done this before and can turn our rejection into an approved resubmission. This is not a development job — you will not be writing app code. It is hands-on QA on real devices plus producing the review documentation Apple asked for. About the app — an AI video studio. Users write prompts and get short-form videos/reels, then refine them in an on-device editor (timeline, trim, layers, audio, export). Built with Expo 54 / React Native 0.81, Skia-based rendering, Auth0 login, iPhone + iPad support. Target audience: brands, marketers, and creators producing short-form social video without a traditional editing suite. We will provide a TestFlight build, demo account credentials, and a walkthrough call so you're not guessing at the flows...

I’m planning a full-cycle mobile app build and I need an experienced developer or small team to take it from concept to launch. The core requirement is clear: this is a mobile app development project. I’m open to suggestions on whether the best route is native iOS, native Android, or a cross-platform framework—convince me with your preferred stack, past results, and the advantages you see. At this stage I’m still refining the exact feature set, so your ability to guide discovery, propose architecture, and flag potential pitfalls will be valuable. Expect to collaborate on wireframes, iterate through milestones, and hand over clean, well-documented source code along with basic test coverage. If you’re comfortable setting up an admin panel or analytics hooks, pl...

I’m ready to commission a focused productivity app for iPhone and iPad that does one thing exceptionally well—let me capture and organize notes in every format I use during my day. The scope is strictly iOS for this first release; Android or desktop versions can wait until the iOS experience is polished. Core requirements • Rich note editor that accepts typed text, embedded images from the camera or photo library, and in-app audio/video recordings. • Seamless playback or viewing of those media files inside the note without forcing users out to another app. • Search that returns results from both text and media metadata so I can instantly find a snippet or recording. • Clean, distraction-free UI that feels native to iOS 17+ and adapts to both light a...

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. Workflow I am after • The user opens the app, sees brief on-screen text prompts, and is guided to keep the device at the right distance and speed; if they drift too far or move too quickly the UI flags it instantly. • While the scan is running, the app automatically records twelve girth measurements around key points of the foot and traces the dorsal outline for pattern work. • Approximately twenty-four still photos are grabbed d...

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. All development must be native for iPhone/iPad, using Swift and the latest Xcode tool-chain to guarantee long-term maintainability and full compliance with Apple’s guidelines. Please show me examples of past work that demonstrate clean code structure, thoughtful interface design, and successful App Store deployment. I’ll review those portfolios closely before we discuss milestones, timeline, and any additional resources you might need. The final hand-off should include: • A fully functional, test-flight-ready iOS applicati...

I’m ready to commission a mobile video editing app inspired by the core, non-AI editing experience of CapCut, built to run smoothly on both iOS and Android. The goal is to give users an intuitive editing workspace for importing, trimming, splitting, arranging and enhancing video clips and photos. Users should also be able to import photos or footage directly from supported social/media accounts where platform APIs permit it—import only, with no direct posting or publishing required. The app should focus on reliable, user-friendly editing tools rather than AI-powered functionality. AI features such as AI generation, AI effects, automatic editing, AI avatars, AI background removal, or similar AI capabilities are not required. Core Features * Video and photo import * Multi-cli...

I’m planning a mobile application that will pair job seekers with job offers on both Android and iOS. The core build must include robust user profiles, along with a fast, accurate job-search experience supported by filters such as location, role … In-app messaging is still open for discussion, so I’m interested in hearing how you would implement or improve that layer while keeping the platform secure and scalable. The app will run dual-sided: one workflow for seekers and another for offers, each with its own dashboard and feature set. I value clean UI/UX, solid documentation, and maintainable code (React Native, Flutter, or Swift/Kotlin native—whichever you feel best fits the brief). Please share at least one live link or store listing of a similar app you crea...

I’m maintaining the open-source iOS project hosted at and need an experienced Swift / Objective-C developer to focus exclusively on bug fixes. The code builds, but several runtime issues and edge-case crashes are holding back a stable release. Scope • Pull the repo, build it with the latest Xcode and iOS SDKs, and reproduce any crashes or malfunctions you encounter. • Trace the root cause in code, patch it cleanly, and document the change in concise commit messages. • Where a fix touches multiple modules, write unit or UI tests that prove it works across those sections. • Submit a pull request so I can review the diff and run the CI pipeline before merging. Deliverables 1. Fork/branch with all resolved bugs committed. 2. Test cases (XCTest) coveri...

I have a fully-functioning e-commerce web application and an Apple Developer account that is already active and verified. What I now need is a specialist who can turn that site into a compliant iOS submission and push it live on the App Store. You will be responsible for: • Wrapping the web app in an Xcode project (WKWebView or an approach you know will pass review). • Creating all required certificates, identifiers, and provisioning profiles. • Configuring the App Store Connect record, including metadata, categories, age rating, and any required privacy details. • Uploading the build through Transporter/Xcode and guiding it through App Review until it is approved and listed. The web content, domain, and payment workflows are already in production; no code...
