We are seeking an experienced mobile app developer to build a performant, cross-platform chess application focused on [insert unique value proposition, e.g., AI-guided blunder training / chess roguelike mechanics / gamified daily challenges]. The initial phase is an MVP designed for fast market validation and user retention. Core Scope & Deliverables: Frontend: Built with Flutter, React Native, or Unity for smooth 60fps board rendering, piece animations, and drag-and-drop mechanics. Chess Logic & Engine: Integration of the open-source Stockfish engine (or / custom rule validator) for move generation, legal move validation, FEN/PGN import-export, and dynamic AI difficulty levels.

I already run a fully-functioning progressive web app and now need it packaged as a native iPhone application so it can be listed on the App Store. The web code stays almost exactly as it is; what I’m looking for is an Xcode project that cleanly wraps the PWA (WKWebView or similar), respects Apple’s guidelines, and passes App Store review. You will receive my existing, detailed UI assets and brand files, so no visual work is required—just make sure the wrapper matches what users currently see in the browser. Along the way I’ll rely on you to configure the correct entitlements, set up app icons and launch screens, handle any required offline caching permissions, and generate the final .ipa ready for TestFlight and public release. When you hand over the project I ex...

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 ...

Flutter App → Google Play Store Publishing & Release (Firebase Backend) I have a completed Flutter camera/photo-editing app (Android, with a Firebase backend — Auth, Firestore, Storage, Hosting) that's feature-complete and needs to go through Google Play publishing. The app was built with AI-assisted ("vibe coded") development — the codebase is functional and extensively commented, but if you prefer projects with fully manual/traditional development history, this may not be the right fit. Looking for someone experienced with Play Console submissions and Firebase project administration to handle the release process end-to-end. What's already done: Release signing keystore configured and working Production Firebase environment separated from dev Pr...

I already have an MVP in hand and am about to launch this brand-new venture, so what I need next is a complete App Store Optimization and visual branding package that makes a strong first impression on both Google Play and the Apple App Store. Your role will be twofold: 1. Refine the store listings so they rank well and convert: keyword research, titles, subtitles, descriptions, tags and any other metadata each store rewards. 2. Create all visual assets in a consistent, cool-toned palette (blues, greens and purples) that reflects the fresh, trustworthy feel I want for the brand. Deliverables • App icon and primary logo in required resolutions • Feature graphic (Play Store) and promotional artwork (App Store) • Full set of high-impact screenshots/preview images for...

I operate a U.S.–based auto-parts store on Shopify and need every completed order to trigger an automatic SMS that delivers the customer’s invoice. The invoice is already generated by Shopify and stored in the usual places; what’s missing is a reliable gateway that can take that data the moment the sale closes and push a text message to a U.S. phone number. Here’s the outcome I expect: • The solution taps directly into my Shopify store (webhooks, Flow, or an app script—whatever is most efficient) and captures order data the instant it becomes “paid.” • A short, TCPA-compliant SMS containing the customer’s name, order number, and a secure link to the PDF invoice is sent through a U.S. gateway such as Twilio, Plivo, or a compara...

I need a small Android-only solution that keeps a field employee’s GPS location streaming in real time for a full 10-hour shift. The phone should start tracking with a single tap, run quietly in the background, and push live latitude-longitude data to an endpoint I can inspect as it happens—no cell-tower or Wi-Fi fallbacks, pure GPS. Please build a lightweight app or service that: • Requests the necessary foreground/background location permissions once and keeps them alive. • Publishes location updates continuously (no noticeable gaps) for up to 10 hours without killing the battery or losing accuracy. • Lets me specify the update frequency before deployment—default can be every 5–10 seconds. • Saves a local log as a safeguard if the conne...

I’m looking for a complete solution that can run full engine, transmission and electrical system diagnostics on my vehicle and compile the findings into a clean, share-ready PDF report. All interaction has to happen through a mobile app, so I can start a scan, watch live data and pull historical reports right from my phone. Here’s what I need delivered: • Mobile app (Android and/or iOS) that connects to the vehicle, triggers the scans and displays live data • Automated generation of a well-formatted PDF report after each scan, including error codes, brief explanations and recommended actions • Option to save, email or export those PDFs directly from the app • Source code, build instructions and a short user guide so I can maintain or extend the solu...

I need up to ten outdated product entries removed from the live catalogue in both the iOS and Android versions of my app. The items are no longer sold, so they must disappear from every user-facing screen, search index, and in-app notification feed without disturbing the rest of the inventory. You will have access to our Firebase-backed admin panel as well as the Git repositories for each platform. The task should include cleaning any linked images or metadata on the server to avoid orphaned assets and making a quick sanity check on the build after the change so the next App Store / Play Store release goes smoothly. Deliverables: • Removal of 1-10 specified listings from production databases • Verification that they no longer appear in either iOS or Android builds (simulator ...

I need a simple Power Apps form that walks a user through a checklist of fewer than twenty questions. The list mixes Text input, Multiple choice, and Yes/No fields, so the control types must switch cleanly as the user moves down the form. Only the Text input questions should reference history. For those, I want the most recent submitted value to appear next to the field where the new answer needs to be submitted, giving users an at-a-glance reminder of what they entered last time without overwriting the editable box. The finished app has to save each run as a new record while still being able to pull the prior value for the relevant text fields when the same user—or any user, if that is easier—opens the checklist again. As long as the experience looks tidy on desktop and mobi...

I know AI will be used for this project, I am totally OK with that, but that's the reason I am not paying a lot of money FastMike — Complete Project Specification 1.

I need a specialist who can create a brand-new Google Play Developer account under my details and walk it all the way through to live publication. All the required personal, payment, and contact information is ready on my side, so there is no paperwork delay—what I lack is time and expertise. The work does not stop at account creation. Once the developer console is active, I also want the first app submitted, its store listing fully optimized (text, screenshots, feature image, tags, keywords), and the dashboard configured for smooth, ongoing account management. Deliverables • New Google Play Developer account, verified and transferred to my ownership • First APK/AAB uploaded and approved, including content rating and policy declarations • Store listing copy &...

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’m ready to build a full-featured concierge mobile application and need an experienced developer who can take the idea from concept to launch on both iOS and Android. The core experience is simple: users open the app, reserve a service or time slot, and pay securely without ever leaving the platform. Here’s what I have in mind: the interface should feel effortless, guiding guests to choose a service, confirm availability in real time, and complete payment using a modern gateway such as Stripe, Apple Pay, Google Pay, or a similar secure solution. I’ll provide brand assets, flow sketches, and a draft design of the app; I’m counting on you for polished UI/UX execution, cross-platform coding (React Native, Flutter, or native if you prefer), and a lightweight backend...

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 want a mobile app that lets me enter a complaint once, choose any contacts already stored in the app, and have that message automatically reach every selected number in one tap—SMS, WhatsApp, or another reliable channel you recommend. Key flow • Create complaint → select contacts → send automatically • App logs date-time and keeps a live counter of “pending days” for each open item until I mark it resolved • Simple list view with filters for open vs. closed complaints and a detail screen showing the running day count There’s no hard deadline, so you can prioritise a clean, maintainable code-base. I’m happy to discuss whether you build natively for Android or use a cross-platform framework such as Flutter or React Native; ...

My app is finished and archived in Xcode, the Apple Developer account is active, and every required asset—icons, screenshots, description copy, privacy policy link—is waiting in a tidy folder. All that remains is the actual submission to App Store Connect and shepherding it through Apple’s review until it appears in the store. Here’s the flow I expect: • Generate the production build with the correct signing certificates and provisioning profiles already sitting in my account. • Set up the App Store Connect record: pricing, territories, app privacy details, compliance questions (no in-app purchases). • Upload the build via Transporter or Xcode, spin up a quick TestFlight group so I can run a last internal test, then move it into “Ready fo...

I’m ready to move an idea from concept to fully-released mobile app and need an experienced developer who can deliver clean, production-ready builds for both Android (Google Play) and iOS (App Store). Here is what I have in mind: • One shared code-base (Flutter, React Native or similar) or two native builds—whichever you recommend for long-term maintainability. • End-to-end support, from initial architecture and UI implementation through testing, store submission and first-release monitoring. • Clear, well-commented source code handed over in a private repository, along with basic setup documentation so I can spin up the project locally. Acceptance will be based on: 1. Stable, crash-free installs on current Android and iOS versions. 2. Successful li...

I’m ready to bring a Google-Store-style shopping experience to iPhone and iPad users first, then scale further once the initial build proves solid. I need a developer who can take the concept from blank canvas to a fully functioning iOS app, guiding me through architecture, UI flow, and App Store submission. The core purpose and feature set are still flexible, so I’ll rely on your expertise to shape best-practice solutions for catalog display, checkout flow, and any integrations that will future-proof the codebase for a possible Android release later. Clean Swift or SwiftUI code, well-commented, and version-controlled in Git are must-haves. Deliverables • Complete Xcode project with readable, maintainable Swift/SwiftUI code • TestFlight-ready build plus assistan...

I need a reliable Flutter developer to give my existing mobile app a quick visual polish and clear out a few lingering bugs. The priority on the design side is refreshing our graphics: the main app icon as well as several background images need to be replaced with new assets I will supply. Please ensure they render crisply on every common device density and appear correctly in both Android launcher and in-app screens. Alongside the graphic swap, I’d like you to track down and solve the minor issues users have reported (occasional crashes on login and a misaligned toolbar on tablets). No new features are required—just clean, well-commented fixes that keep the current functionality intact. Deliverables • Updated app icon integrated into the build • All specified b...

I have a RecyclerView driven by a LinearLayoutManager. Card taps are currently picked up through an OnPress handler, and I already keep the underlying data in a ViewModel. The problem is simple: when a user opens a detail screen from any card and then presses the back button, the list always jumps back to the very top instead of revealing the card they originally tapped. I need the list to remember its exact scroll position so that returning feels seamless. You’re free to solve it however you feel is cleanest—saving and restoring the layout manager state, using the Navigation component’s back-stack handling, or any other proven method—as long as: • the previous scroll position is restored every time, • orientation changes don’t break the fi...

DO NOT RESPOND USING AI. I WILL AWARD THE PROJECT TO A PERSON THAT RESPONDS WELL WITHOUT THE USE OF AI AND SHOWS ME THEIR PAST EXPERIENCE WITH A VIDEO SIMILIAR TO THE BELOW.

I’m looking for a developer who can build a clean, intuitive application devoted entirely to personal note-taking. My goal is a distraction-free space where I can quickly jot ideas, organise them in a logical structure, and retrieve them just as easily. Platform choice is flexible—desktop, mobile, or a web-based hybrid—so feel free to recommend the stack you think suits a personal workflow best. Key considerations • Speed and simplicity: the interface should load fast and stay out of the way while I write. • Local data ownership: notes must remain private, with any optional cloud element clearly explained and under my control. • Future-proof code: well-commented, modular, and easy for another developer (or me) to extend later. When you respond, show me ex...

I will send you the complete ChaloTrain source as a ZIP. Your first task is to open the project in Android Studio, iron out every build error and bug, and verify that the app name, icon, package ID and other Android-specific settings are correct. Once the code compiles cleanly I need both a release-signed APK and a Play-ready signed AAB. I have gone through Play Console once before, so I know the basics, but I’d like you to take the lead this time—create or update the listing, upload the bundle, handle content ratings, privacy policy links and any review feedback, and stay on the job until the status reads “Published”. Deliverables • Project configured and building without errors • Release-signed APK and AAB provided • App successfully uploa...
