My iPhone running iOS 15 was recently stolen, and I need a security professional who can ethically gain access to it, uncover its current location, and pull a full copy of the data still stored on-device or synced to iCloud. The priority is threefold: pin down the handset’s live coordinates so I can share them with the authorities, retrieve every message and call log for evidence, and recover all photos and videos that may not yet be backed up. Any lawful, forensically sound method is acceptable as long as it keeps my Apple ID credentials secure and preserves the chain of custody. Deliverables (all in encrypted containers): • Verified GPS location (lat/long + timestamp) • Complete message and call-log extraction (including deleted items if possible) • Full photo...
My iPhone is missing and, although Find My iPhone was enabled, every attempt to track it through iCloud returns “offline.” I need an experienced, verifiably ethical security professional who can go beyond the standard Apple toolset and pinpoint the handset’s current or last-active location so I can pass accurate information to local authorities. The phone runs the latest public iOS release, Find My iPhone was active, and I still have full access to the associated Apple ID, IMEI and carrier account. What I need from you is technical know-how: advanced iCloud forensics, OSINT, cell-tower or Wi-Fi-probe analytics—whatever lawful methods can surface a usable latitude/longitude or provable last-seen data. Deliverables (concise and clear): • A verified location c...

I work with an agency that regularly launches mobile titles and we are ready to partner with someone who already uses a Google Play Console account frequently and is comfortable publishing games. Your console must be verified, in good standing, and old enough that new releases pass review without extra testing hoops. Here’s how the collaboration will run: you keep full ownership of the account. I send you the prepared APK/AAB, assets, and listing text each week. You provide managed or supervised access (or simply handle the upload yourself), we go through the standard publishing flow together, and once Google confirms the release, I trigger payment immediately through Freelancer. The arrangement repeats weekly, so you can expect a steady cadence of uploads and payments as long as ev...
My existing Flutter codebase already builds and runs, but it now needs both extra functionality and a polish pass. The tasks are straightforward: • Add user authentication that supports secure sign-in and keeps sessions persistent across both Android and iOS. • Wire up in-app purchases so that users can buy consumables as well as subscriptions inside the app. • Enable push notifications, ideally through Firebase Cloud Messaging, and show them reliably when the app is in foreground, background, or killed state. • Resolve performance slow-downs (notably long startup times and sluggish list scrolling) and fix the UI glitches that cause occasional mis-alignment and flicker on some screens. I will provide the current Git repo and a brief walkthrough of the architectu...
I’m planning a new web application and need a seasoned full-stack partner to carry it from idea to launch. The core product will be a browser-based app, but I want it engineered responsively so users on both iOS and Android enjoy a native-like experience the moment they open it. I’m flexible on timeline—quality is more important than speed—so you’ll have room to make thoughtful architectural decisions. I expect you to handle everything from setting up the back-end (database design, APIs, authentication) through the front-end (modern JavaScript framework of your choice, clean component structure, mobile-first styling) and deployment to a cloud host. Please share links to previous web apps you built that behave flawlessly on mobile, and outline the tech st...

Deliverables I will be expecting: • A concise test plan outlining device/OS coverage before you begin • Clear, reproducible defect reports in JIRA (or Excel if you prefer) with screenshots or short videos • A final test summary confirming all critical paths are green and any outstanding issues are classified by severity Acceptance criteria: all high- and medium-severity issues must be doc...
I need a complete, production-ready marketplace where local service providers—plumbers, electricians, carpenters, pandits, tutors and similar trades—can sign up under clearly defined categories and sub-categories while customers discover and contact them instantly. The build must ship native apps for both iOS and Android. For users, the experience centres on a fast search and filter workflow that lets them narrow providers by category, sub-category, rating or distance and then reach out through one-tap phone or WhatsApp. A clean, lightweight UI is essential so the first result appears within seconds of launching the app. Providers will manage their own presence through a dedicated app. They must be able to create and edit a public profile, add or remove the services they offe...
CASPO – FULL PRODUCT EXPLANATION FOR DEVELOPERS 1. What CASPO Is CASPO is a mobile-first real estate marketplace application designed to work like Instagram, but instead of social posts, users interact with real estate listings. The core idea is: Agents/proport owners post properties the same way they post photos or video on Instagram, and people searching for places interact, message, and find housing faster. 2. Main User Types & How: Customers / Renters / Students These users: - Create an account - Browse property listings in a feed - Send direct messages to property owners or agents - Receive notifications when new matching properties are posted - Post a property request (order) describing what they need 2.3 Agents / Brokers Agents: - Register as agents - Define c...
I want a clean, cross-platform grocery store app built with Flutter that runs smoothly on both Android and iOS. The scope is intentionally compact—about seven or eight screens—but each must feel polished and production-ready. Here is the core flow I need: • Splash → Mobile-number OTP login (no email, social, or multi-language layers—just a straightforward phone-based sign-in) • Product catalogue with search and category filters • Cart review and quantity update • Checkout that accepts online-banking payments and offers Cash-on-Delivery as an alternate option • Delivery or in-store pickup selection with status tracking • Order confirmation & basic profile / past orders screen I will provide branding assets and a simple RES...
I need a polished mobile app (iOS and Android) that lets clients leave and browse reviews for independent hairstylists across NYC and NJ. The core experience revolves around collecting and displaying feedback, so every stylist profile must show star ratings, written comments, and photo uploads in a clean, intuitive layout. Discovery is equally important. Users should be able to: • search a stylist by name and social media handles, • browse nearby options through location services, • and apply filters for specific services. I have an early Flutter codebase, yet I’m flexible—React Native, Swift/Kotlin, or a fresh Flutter rebuild are all acceptable if they help us reach a smooth UI/UX. Integrated location handling, thoughtful interface design, and a future-ready a...

I need a hands-on evaluation of popular digital lending services in India. You will download the mobile apps, visit the corresponding web portals and walk through a full loan application.

My Flutterflow project has drifted from the original designs and, on top of that, parts of the navigation stack no longer behave as intended. I need a capable Flutter / Flutterflow developer to jump in, tidy things up, and return a clean, working build. Here is what’s currently wrong: • Layout problems: several screens have elements that don’t respect safe areas, text overflows, or stretch oddly on tablets. • Broken design elements: buttons that lost their styles, gradients that vanished, icons mis-sized. • Navigation issues: taps sometimes open the wrong page, the back button gets stuck on certain flows, and bottom-nav state is inconsistent after deep links. What I expect from you: • Update the affected pages directly in Flutterflow so the finished pr...

The core of the project is straightforward: shoppers open the app, browse the menu, create an account, and place an order.

I already have a playable prototype of an educational endless runner for kids; the core loop—auto-run, jump, obstacles, and simple quiz moments—works fine, but it still feels like a prototype. I now want to transform it into a production-ready mobile release. Performance is the top concern. In-game lag and sluggish restarts appear after extended play, so the end goal is a rock-solid 60 fps that holds after long sessions and multiple resets on mid-range Android and iOS devices. Next comes architecture. The current code grew quickly and now shows its seams, especially around animation handling. I need it refactored into a clean, modular structure that’s easy to expand and maintain. The game’s feel also needs attention. Character movement must be snappy and visually...

I’m building a cross-platform inventory application that talks directly to NFC tags so that stock can be added, counted, and located with nothing more than a phone.

The scope right now is an MVP for both iOS and Android. I already have the product vision, rough wireframes, and a shortlist of cloud back-ends—Firebase and Supabase are front-runners, but I’m open if you have a strong preference. What I need is a developer who can turn those screens into a fast, stable mobile experience, handle the low-level NFC read/write flows, and guide our release into TestFlight and Google Play’s internal testing tracks. ...
