从235,540个评价中,客户给我们的 iPhone Developers 打了4.9,共5星。I’m ready to turn my idea, “Yono,” into a polished mobile title that runs flawlessly on both iOS and Android. The core requirement is a game that offers a satisfying single-player journey but can also switch seamlessly into multiplayer sessions. I’m open on genre—puzzle, adventure, or even action—so long as the concept feels fresh and the mechanics stay intuitive for touch controls. You would handle the full development cycle: refining the concept with me, producing art and audio that match an upbeat, modern aesthetic, building the core mechanics, and implementing reliable real-time or turn-based multiplayer. A lightweight back-end for player accounts, matchmaking, and basic stats is essential, whether you prefer Firebase, PlayFab, or a similar service....
I’m building the first product for my health-tech startup: a cross-platform mobile app focused on continuous patient monitoring. The core workflow is simple—patients pair their wearable or connected device, the app streams real-time health data to a secure cloud, and both patient and clinician receive instant, actionable insights. Key functionality • Real-time data tracking pulled from Bluetooth-enabled wearables or manual input, visualised in clear, trend-based dashboards. • Alert notifications that trigger when readings leave predefined thresholds, with configurable urgency levels for patients and care teams. • Doctor-patient communication via in-app, encrypted chat and optional teleconsultation hooks so clinicians can respond to critical alerts immediat...
Across my web applications, internal network infrastructure, desktop endpoints, company phones, and public social-media profiles, I need a full-scope security examination. The engagement must blend hands-on penetration testing with a structured security audit so that both technical weaknesses and policy gaps are captured in one clear deliverable. Scope • External and internal testing of web apps, network segments, desktops, mobile devices, and social-media assets • Manual and automated discovery using industry-standard tools such as Burp Suite, Nmap, Metasploit, Wireshark, Nessus, Kali Linux, and OSINT/social-engineering toolkits • Coverage of OWASP Top 10, SANS Top 25, common mobile attack vectors, and configuration hardening checks Deliverables • Comprehen...
I need a full-featured mobile shopping experience that runs smoothly on both iOS and Android. Core requirements are straightforward: customers must be able to browse a catalog, add items to a cart, and check out securely with popular payment gateways. A clean product search, push notifications for order updates, and basic account management round out the MVP. I will supply brand assets, product data in CSV, and API documentation for our existing inventory system. Your job is to design the UI, wire the front end to those APIs, and ensure the app sails through App Store and Google Play review. I’m comfortable with React Native or Flutter, but if you have a different cross-platform stack that hits the same quality bar, let’s discuss it. Source code, build scripts, and a brief &l...
I want a lightweight mobile app that sends one plain-text push notification to every user each day on both iOS and Android. Inside the app, the user should be able to turn the alert on or off and choose the exact time it arrives; all of this can live in a simple settings screen and be stored locally—no back-end accounts or web portal are needed for this first release. Core scope and deliverables • Universal build for iOS and Android (native, Flutter, React Native—use what lets you move fastest) • Push service configured with APNs / FCM so the alert fires even when the app is closed • Minimal UI: welcome/info screen plus a settings screen for the daily time picker and on/off toggle • Local storage of the preference and correct handling of time-zone c...
I need working Flutter code that lets a single deep-link URL open my app (or the web build) and take the user straight to a predefined screen. The same link must behave correctly on Web, Android (AOS) and iOS. The job is straightforward but time-critical: • Configure and wire up the deep-link handler so that the route is captured at launch or from the background and the target screen loads with the right state. • Supply concise setup steps for each platform (Android manifest / iOS , Apple App Site Association file, web rewrite rules, etc.) so I can reproduce the result in my own project. • Give me a minimal example project or the relevant Dart files plus platform configs, along with a short README explaining how to test the link end-to-end. I’m ready to revie...

Saya ingin mengembangkan sebuah aplikasi mobile berbasis AI untuk kebutuhan pengembangan produk. Aplikasi ini harus bisa berjalan mulus di iOS dan Android sekaligus, sehingga satu basis kode lintas-platform—misalnya React Native, Flutter, atau teknologi serupa—akan sangat membantu efisiensi.

I want to replace manual spreadsheets with a straightforward mobile solution focused on data entry. The app’s sole purpose is data collection, so the interface should open directly to a clean form where users can type values, scan barcodes, attach photos, and tag GPS coordinates if available. Core requirements • Runs smoothly on Android; an iOS build is a welcome bonus. • Customisable form fields that I can add, reorder, or hide without editing code. • Offline capture with automatic sync to a lightweight cloud database (Google Sheets, Firebase, or another simple option you propose). • Export options to CSV or Excel so I can review the raw data anytime. • Basic user authentication—email + password is enough—to keep entries separated by u...
I am starting a green-field project that includes both a cross-platform mobile app and a companion website focused on clear, engaging information delivery. The two fronts must share a single code-friendly backend and integrate machine-learning algorithms at their core. Mobile side The app needs seamless user authentication, real-time push notifications, and an in-app analytics layer so I can monitor engagement patterns from day one. While I am open to React Native or Flutter, I expect smooth performance on iOS and Android with clean, modern UI components. Web side The website’s main job is to present our content elegantly and quickly—think blog posts, tutorials, and white-papers—with the same login system the app uses. A responsive front-end framework (, Nuxt, or simila...

Quiero convertir la experiencia de Solo Leveling en una aplicación Android que impulse a los usuarios a “subir de rango” en la vida real. La idea es reproducir el famoso tablero interactivo del anime: allí se mostrarán sus estadísticas, avances y recompensas mientras completan misiones diarias y objetivos de largo plazo. La lógica central parte de una base de datos que almacene: • los niveles y rangos, • las habilidades y conocimientos declarados o evaluados, • los puntos que cada usuario obtiene al cumplir retos. El sistema tiene que evaluar tres ejes principales ―conocimientos, habilidades y entrenamiento físico― y conceder puntos adicionales por actividades como lectura de libros o la realización de cursos...

I want to bring a full-scale “CRMP” experience to mobile, so the game has to feel as lively and flexible as titles such as RP Grand Mobile—but run smoothly on both Android and iOS. Multiplayer functionality, an open-world environment, and deep role-play systems are the three pillars of the project. You will take the idea from first prototype all the way to App Store and Google Play release, including the server back-end that keeps sessions persistent and handles everything from chat to economy. I’m open to your preferred stack—Unity, Unreal, or a custom engine—as long as the end result delivers a stable, cheat-resistant experience and can be updated over time. Key deliverables • Detailed game design document that captures mechanics and progres...
I’m building a mobile companion that teaches golfers to perfect their swing through on-screen drills, instant feedback and progress tracking. The app must ship on both iOS and Android from a single codebase, so I’d like it developed in React Native. If you can demonstrate clear advantages, I’m willing to consider a Flutter approach, but React Native is the baseline expectation. App will help golfers record and analyze their swinging on phone screens What I need you to tackle: • Implement core screens (on-boarding, video-capture, swing analysis, drill library, progress stats) following the Figma wireframes I’ll supply. • Integrate basic analytics, in-app purchase hooks and secure cloud storage (Firebase preferred). • Package and hand over prod...

I need a straightforward mobile application whose single purpose is to buzz at times I specify. The app will let me enter reminders manually, store them locally, and then play a loud, unmistakable buzzer sound when each reminder is due. No voice control, no preset schedules—just a clean screen where I can add, edit, and delete reminder times and short labels. I’m after a polished, glitch-free build that runs on modern smartphones, with an intuitive layout and standard notification permissions so the alert pops even if the phone is locked or the app is in the background. A quick settings panel for volume and repeat interval would be useful, but simplicity is more important than feature bloat. Deliverables: • Fully compiled mobile app (Android, iOS, or a cross-platform pac...
I’m building an online “rental boyfriend” platform and need both a full-featured website and companion mobile apps (iOS and Android). The core of the product is simple: visitors browse verified profiles, check availability, and place a booking—nothing more elaborate for now.

I need a mobile developer to bring my existing app up to the latest platform version and smooth out any issues the update introduces. This first step is strictly a maintenance pass—no payment is attached to it. Once the upgrade is stable, I will open a paid phase to add new AI-driven matching features.

I need a mobile application that lets me watch my CCTV system in real time and review recorded footage from anywhere. The app has to run smoothly on both iOS and Android and should connect to my existing NVR/DVR or IP cameras over a secure, encrypted channel. Location Preference: Developers based in Bangalore, Karnataka are preferred. Anyone from Bangalore Can DM Core scope • Live View: a low-latency stream that opens quickly every time. I am open to your advice on extras such as multi-camera grids, PTZ control, or motion-triggered push notifications if you have proven approaches. • Playback: scrubbing through the timeline, pausing, and jumping to specific times must feel instant and intuitive.

I need a complete visitor management solution delivered as a mobile app for both iOS and Android. When someone arrives, they will scan a dynamically generated QR code on a kiosk or reception tablet, then fill in their name, company, host, reason for visit, and any custom fields I define. The moment they submit, the system records an exact check-in timestamp; on departure they scan again for the checkout timestamp, closing the visit record automatically. Administrative access to the dashboard must be secured with two-factor authentication so only authorised staff can review real-time visitor logs, export reports (CSV/PDF), and manage the QR codes. Push notifications or email alerts to the host on visitor arrival are essential. Core deliverables • Universal iOS & Android apps bu...
I have an “audio social party” app that targets both iOS and Android, and I’m ready to take it live. Most of the groundwork is done, but two key elements still need to be wrapped up before submission: the random-matching call and random-matching chat features. Once these are integrated and tested, I want the builds prepared, signed, and successfully published on the Apple App Store and Google Play. Here’s what I expect: finish those final features within the existing codebase, make sure everything passes Apple’s and Google’s latest review guidelines for audio and social interaction apps, then handle the entire deployment flow—store-listing metadata, screenshots, TestFlight / closed testing, bundle uploads, and the inevitable round of reviewer ques...

I’ve just released my iOS and Android app and I’m ready to drive real traction with Meta ads. All the raw materials are in place—promo video, screenshots, and several copy variations I’d like to test—yet I need a skilled hand to turn them into high-performing campaigns aimed squarely at generating installs. The app is called Carbsequence ( http:// ) it is an AI food tracker, but the uniqueness of it is that it ties your calories and macros to the exercise you do (this is unique and no one does this) so when you eat something, it tells you how much activity you need to burn it off. It also tells you how it affects your blood sugar. My priority is simple: app downloads. Because my audience is interest-based rather than tied to a strict age bracket or location...

Project Title: Fix OTP Country Code Issue in Mobile App (Wrong Country Code Sent) Project Description: Hello, I need an experienced mobile app developer to fix an OTP issue in my application. Problem: When users select their country and request OTP verification, the app always sends the phone number with country code +91 (India) instead of the country code chosen by the user. Example: If user selects Iraq (+964), Kuwait (+965), or any other country, the app still sends OTP only with +91. What I Need: - Check and fix country code picker / phone input logic - Make sure selected country code is passed correctly to backend/API - Fix OTP sending process for all countries - Test with multiple countries - Ensure app works properly on Android / iPhone (if applicable) Please Apply If You Ha...
I have an almost-ready iOS app sitting in Xcode with every certificate and provisioning profile already in place. What’s left are the final two tasks inside App Store Connect to push the build live. Alongside that, there’s an older version of the same app already available on the App Store. I need a knowledgeable iOS release specialist to: • Review the live build versus my new build, explain the pros and cons of submitting the fresh version as an update or publishing it as a brand-new app listing. • Complete the submission flow (screenshots, compliance forms, version notes, release configuration) and trigger the release so it reaches the store without rejection. Everything has been compiled with Xcode for iOS only, distribution method set to “App Store,&...
I’m ready to bring a sleek, community-driven marketplace to life—think the discovery experience of Deliveroo or Uber Eats, but tailored for any trusted local service or business. The goal is a polished, repeat-use platform that lets users browse by category, land on engaging business profile pages, watch short intro videos, and complete bookings or online orders in just a few taps. Core scope • Native apps for both iOS and Android, built from the same scalable codebase so we can grow fast without duplicate maintenance. • A premium design system that reinforces credibility through smooth navigation, refined typography, and consistent branding elements. • Business profile pages with embedded intro videos as the hero feature, supported by ratings, reviews, pr...
I’m ready to build the first-generation mobile app for our golf company and want it released simultaneously on iOS and Android. In this initial version the priority is straightforward functionality, not flashy extras. Here’s what Gen 1 must do: • Pull live information from the Google Sheets we already use for player notes and make it easy for a coach or athlete to browse and update those records on their phone. • Store and display fitness data so users can track workouts, mobility routines, and training metrics alongside their golf notes. • Let me upload short swing videos or screen-recorded tips and have them play smoothly inside the app. Access will be secured with a simple email-and-password sign-in; no social logins for now. I’ll supply the c...

I need a full mobile app built from the ground up that lets users connect, share content and chat in real time. The final product must run smoothly on both iOS and Android, so feel free to suggest whether you prefer a single codebase approach (React Native, Flutter, etc.) or separate native builds in Swift and Kotlin—what matters is reliability, speed and a modern UX.
