Necesito desarrollar una aplicación móvil disponible tanto en iOS como en Android. El corazón del proyecto es la integración con redes sociales: los usuarios deberán poder iniciar sesión con sus cuentas existentes, compartir contenido dentro de las principales plataformas (por ejemplo Facebook, Instagram o Twitter) y ver sus propios feeds o perfiles enlazados desde la app. Cuento con la idea general y algunos bocetos iniciales; requiero que conviertas esos conceptos en una aplicación funcional y estable.

I need our web-based CRM, currently built in React, re-implemented as fully native apps for both iOS and Android. The existing REST and GraphQL endpoints are stable, so the job is mostly about translating interface logic and screens into Swift (or Objective-C) and Kotlin/Java while keeping parity with the browser version. Core functionality to reproduce • Secure user authentication with profile management • Full customer management workflow (create, edit, segment, assign, delete) • Analytics and reporting dashboards identical to the web charts and tables Design requirements The mobile UI must replicate the current design pixel for pixel. All colours, typography, spacing, and animations already exist in Figma; simply mirror them exactly so our users experience no ...

I am commissioning a bilingual iOS application—Arabic first, English second—that delivers live Bitcoin and selected-coin data with a professional, sleek interface entirely in Swift and SwiftUI. The app’s core revolves around real-time price feeds, historical price charts, and razor-sharp alerts that keep users ahead of major market moves. Arabic users will enjoy a true RTL layout, while English users see a standard LTR presentation, all driven by Apple’s native localization tools. Key functionality I need implemented: • Current price updates streamed from a reliable REST source • Historical price charts for deeper context • Push notifications for major price changes via Firebase Cloud Messaging • In-app alerts that surface whale activity...

I want to ship a lean Android + iOS application that can 1) establish a Bluetooth Low Energy link to my peripheral and move data back and forth, and 2) instantly push out a user-defined BLE packet the moment the phone detects an incoming call. The BLE work is classic data-transfer: discover the device, pair, subscribe to characteristics, then read/write packets on demand. Stability in the background is critical; the link must stay alive (or reconnect quickly) when the screen is off. When a call arrives the app should listen to the system broadcast (Android) or CallKit/VoIP push workaround (iOS), pull the string the user previously defined, and write it over the existing BLE connection without visible delay. Please send a concise, detailed project proposal outlining: • your ...

I’m ready to commission an Android-only audiobook application and need an experienced mobile developer to take it from concept to Google Play release. At its heart, the app must stream and locally cache audiobooks, let listeners drop unlimited bookmarks while they listen, and handle one-tap downloads for fully offline playback. Monetisation is essential: new titles will be sold individually, so please wire the catalogue to Google Play Billing for in-app purchases. Authentication will be straightforward email-and-password login—either a lightweight back-end you spin up or a Firebase Auth integration works for me so long as it’s secure and quick for the user. Core flow I have in mind • Launch ➜ user signs up or logs in • Library screen lists available au...
My Flutter app is finished and tested on my end; what’s left is to get it live on both Google Play and the Apple App Store. I already have active developer accounts for each platform and all listing assets—screenshots, icons, long/short descriptions—are prepared. I simply need someone who knows the submission pipelines inside-out to take the project across the finish line. Here’s what I’m looking for: • Build & sign the final release packages (AAB for Google Play, IPA for iOS) or validate the ones I provide. • Upload everything through Play Console and App Store Connect, filling in required metadata, privacy labels, content ratings and policy declarations. • Set up closed/internal testing: Google now mandates tester access prior to pu...
source code: My current code-base is written entirely in Swift and already live in Xcode; however, it now needs a solid refresh. I want the project audited, improved, and extended where sensible—this may include streamlining the UI, tightening performance, or wiring in a few new features that have been on the backlog. You’ll start by reviewing the repository (Git), reading the short README I’ve written, and walking me through any questions so we can prioritise tasks together. Once the roadmap is clear, go ahead and: • refactor or redesign modules that slow the build or affect user experience, • implement the agreed-upon feature enhancements, • tidy up comments and add inline documentation where the logic is non-trivial, • deliver a concise ...
I need a straightforward mobile application that lets my team and I handle property inspections, repairs, and routine maintenance right from our phones on both iOS and Android. Each form should include Yes/No checkboxes, a comment area, and the option to attach photos so we can quickly document issues like a leaky faucet or damaged flooring. Real-time sync is essential: when one of us completes or edits a checklist, everyone else must see the update instantly. I’d like the data stored in the cloud—Firebase, AWS Amplify, or a similarly reliable backend—so nothing sits only on a single device. A second core feature is tenant-initiated work orders. Every unit should have a unique, scannable QR code. When tenants scan it, they’re taken to a simple screen (or a p...
Project Description I am seeking a high-level mobile app designer & developer (or a strong team) to build a multi-livestock management application inspired by the “Mqane” app, but with a much broader scope and stronger foundation.

I already own a full, unmodified copy of the WoWonder PHP script plus the matching Android Timeline App (a release from within the past year). All I need is an expert who has done this exact job before to turn that code into a Play-Store-ready build. Here is what has to happen: 1. Connect the Android source to my live WoWonder PHP site, including any custom server tweaks the API needs. 2. Reskin: swap in the new app name, splash screen, logo (I will supply the artwork) and adjust the primary colours so the interface matches the brand. 3. Change the package name to a unique identifier. 4. Produce a signed APK and an AAB bundle I can upload straight to Google Play. 5. Send brief notes on anything I must replicate if I update the code later. The server runs a customised configurati...

I need a concise, highly watchable demo that captures how users move through Ikration on both iOS and Android. The video should feel casual—think YouTube walkthrough rather than a stiff corporate tutorial—yet still guide viewers clearly from the Registration/Login screen to the Main Dashboard and into the Settings & Preferences area. Smooth transitions, on-screen callouts, and a friendly voice-over (or captions) will make the journey easy to follow. Alongside the video, I also want a small set of branded visuals: banners for the app store pages, annotated screenshots that highlight key taps or swipes, plus any icons or overlays you plan to drop into the edit. Canva, Photoshop, Figma, Premiere Pro, Final Cut, Camtasia—use whatever combination you’re comfortable ...
I need an iPhone-ready application that shows a clean list of downloadable audio files and lets users save those tracks locally for offline listening. The screen can be as minimal as a table or collection view; what matters is that each row presents a track name, a short description, file size, and a visible progress indicator while the file is coming down. The catalogue itself will live on a remote endpoint that returns basic JSON. I will provide the final URL and the exact fields; expect typical values such as id, title, url, and size. Pull the list on launch (with pull-to-refresh for good measure) and cache it so the user still sees something when the device is offline. Key interactions • Tap a row → start download in the background and update progress live. • Complet...

I want a single code-base app (React Native or Flutter is fine if it meets Apple and Google policies) that lets my users save any public video or audio they encounter online—Instagram Reels, YouTube clips, Facebook posts and beyond—directly to their device. The app must automatically detect the highest available quality, then offer MP4 for video and MP3 for audio before placing the file in a tidy, built-in library. The admin could see each user link they downloaded in a admin dashboard where he could see all people whom they are using the app. Core flow • Paste or share a link into the app • Choose format (MP4 or MP3) and resolution/bitrate • File downloads in the background, lands inside an in-app folder structure the user can rename, move or delete &bu...

I need an end-to-end delivery application that ships simultaneously on iOS and Android. The product will serve two audiences—customers who place and track orders, and couriers who accept jobs and update their status—so the UX must switch cleanly between those roles. Core features are non-negotiable: live GPS tracking that remains accurate to the meter, a secure in-app payment flow (card and wallet support preferred), and automated push notifications at every key milestone from pickup through drop-off. I’m comfortable with React Native, Flutter, or any other modern cross-platform stack as long as performance is smooth and native APIs for location, payments, and notifications are handled properly. Please structure the build so I receive: • Production-ready iOS and ...
I’m ready to move my physical-goods store onto mobile and I need a developer who can deliver a polished, full-featured e-commerce app for both iOS and Android. Core buying flows must feel fast and familiar—browsing catalogues, adding items to a shopping cart, checking out through a secure payment gateway, and leaving product reviews once orders arrive. Beyond the standard shop functions, two extra capabilities are critical: • Quotation sharing – users should be able to receive quote inside the app, and forward or save it with a tap. I’m open to the framework you think best suits a dual-platform launch (React Native, Flutter, or native builds), as long as the result is smooth, scalable, and easy for me to update with new inventory down the line. Delive...
I need a Flutter iOS developer to fix two small but visible issues in my live app and then push the corrected build to the App Store. First, the “Share Invites” and “Invite Guest” buttons are currently unresponsive on iPhone; the dialog flashes on screen and closes immediately. I need that behavior fixed so the pop-ups remain active and function as intended. Second, within the attendance workflow I want a third RSVP choice. Right now users can tap only “Yes” or “No.” Please add a “Maybe” option wherever an RSVP update is made. Simply, fixes needed: 1 - Share invites (csv) 2 - Invite guest 3 - Maybe (guest invite) If you have recent experience with Flutter apps on iOS and can turn this around quickly, let’s get started...
I need a straightforward way to pinpoint where a specific mobile number is during standard business hours. GPS tracking is the preferred method, and I only need periodic location updates rather than a constant real-time feed. The end goal is to improve our customer service workflow: when a caller rings in, I want to know the current area of the handset, the registered owner’s name, and the business name (Darren) so my team can respond accurately. Please outline the steps, tools or APIs you’ll use for GPS-based positioning, how frequently you can push those updates, and how you will present the data—map view, simple coordinates, or a brief report are all acceptable as long as it’s clear and reliable. If you’ve implemented similar tracking or geofencing solut...
I am kicking off Phase 1 of the Expressions app exactly as defined in the signed Phase 1 SOW, Annex B, and Annex B-2.

The keyboard must: • Enforce the system-level identity lock, • Invoke backend AI execution to generate anchor- and burst-style emoji outputs, and • Surface generated results in real time within the keyboard experience. Authentication must rely on Sign in with Apple and Sign in with Google. The application must deny access, or selectively restrict features, when a user’s subscription status is not validated....
I’m looking for an experienced mobile QA tester to test a dating app on both iOS and Android. This is not a “click around and say it works” role.

I’m building a secure, full-featured e-commerce solution that runs smoothly on iOS, Android, and the Web. The core stack can lean on Python for the API layer, with Java or C++ wherever high-performance modules make sense, but I’m open to a workflow you can justify that keeps code clean, well-documented, and easy to maintain. Core scope The first release must cover user account management (registration, login, password reset, profile editing) and end-to-end payment processing with major gateways. A responsive storefront, basic product catalogue, and an admin dashboard will round out the MVP.
