Από 229,121 αξιολογήσεις, οι πελάτες αξιολογούν τους iPhone Developers με 4.9 από 5 αστέριαI'm looking to create an engaging tycoon game on Roblox. Ideal Skills and Experience: - Proven experience in Roblox game development - Strong background in tycoon game mechanics - Proficiency in scripting, building, and UI design on Roblox - Ability to showcase past work related to Roblox games, especially tycoon genres Please include relevant past projects in your application. I’m looking for a Roblox developer/team to build the full game, not just individual scripts. The game is a Mutant Zoo where players spin for animal DNA, combine two DNA samples in a mutation machine, collect the resulting mutants, place them in their zoo, and earn cash per second. I need someone who can handle the main gameplay systems, RNG/rarities, inventory, mutation system and timers, zoo/animal p...
I need a complete mobile app that runs smoothly on both iOS and Android and showcases advanced facial-recognition capabilities. The core of the build is a camera workflow that can: • Face identification • Emotion detection • Age and gender estimation Those three features must fire quickly on-device (or via a lightweight cloud microservice if latency is acceptable) and return an easy-to-parse JSON result I can feed into future modules. The interface should feel modern and sleek with clean typography, subtle animations and dark-mode support. You’ll own the full stack—from selecting the best SDK (e.g., Apple Vision, Google ML Kit, OpenCV, or a custom model in TensorFlow Lite / Core ML) to wiring up the UI in Swift/Kotlin or a unified framework like Flutte...
I'm building a mobile racing game that puts players right inside the cockpit: a pure first-person experience. The core is straightforward racing, but it must ship with three distinct modes—quick Time Trial laps, real-time Multiplayer, and a progressive Campaign that unlocks new content as players advance. Unity or Unreal expertise is fine, as long as the vehicle physics feel authentic, the touch/tilt controls stay responsive, and mid-range devices maintain smooth frame rates. Online features such as matchmaking, leaderboards, and cloud saves should plug into a backend like PlayFab or Firebase. Visually, I’m open to either realistic or stylised art; the key is that speed and clarity in the cockpit come through. Deliverables • Playable first-person build featuring at ...
I need to move a published Android app from one Google Play Console account to another. I already have full access to the source account and will supply access to the destination account as soon as we start. The goal is to transfer only the app itself—no user data, analytics, or auxiliary assets need to follow it. Your job is to handle every step of Google’s official “App Transfer” procedure: preparing the app (package name, payments profile, policy status), submitting the transfer request form, and confirming successful migration when Google completes the switch. Please keep a concise record of each action and any messages from Google so I can archive them. Acceptance criteria • Google’s confirmation that the transfer is approved • The app appea...
I have an iOS prototype written entirely in SwiftUI that’s almost ready for prime time, but a few pain-points are holding it back from the App Store. Right now I’m seeing: i made it in openai-codex- i need someone look at the prototype i made, make sure no bugs, all smooth, works well and launch it in the app store - i also need the code from them and access in order to maintain it myself - make sure its all working well efficiently and clean. Launch in app store. then give me code and all for it to maintain myself. Also want someone who can do it in one chunk and happy pay the one off. not paying hourly or extras. • Crashes in several flows • Performance lags on older devices • UI/UX problems that make some screens feel rough Your mission is to hunt ...
The mobile app is already well underway, but I now need a seasoned developer to take it across the finish line for both iOS and Android and, at the same time, give the iPad layout the attention it deserves. Here’s where things stand and what I expect next: – Core functionality is largely in place, yet a handful of screens and background services still need wiring up and thorough testing on iPhone, iPad, and the most common Android devices. – The iPad build runs, but the interface is still iPhone-sized; I’d like a clean, adaptive layout that feels native in both portrait and landscape modes, with smooth split-screen behaviour. – Once the last pieces are coded, I’ll need you to run a full QA pass, resolve any crashes or UI glitches, and prepare c...

I’m putting together a simple mobile app for a personal family event and I want it to run on both Android and iOS from a single code-base. The app’s main purpose is entertainment: I need a built-in game that guests can play during the gathering—think light, fun and quick to learn. Everything else is secondary. Platforms Feel free to use Flutter, React Native, Unity, or any other framework you trust for shipping clean builds to Google Play and the App Store. Stability and fast loading times are more important than the specific stack. Core Feature • One self-contained game themed around the event, including basic UI, sound, and score tracking. I’ll supply artwork ideas; you handle coding and polish. Nice-to-haves (quote separately) • Simple schedule...
AURA began as a neighbourhood grocery store in Kaliyaganj, West Bengal, and I now want to give it a digital life that truly fits non-metro India.

I value solutions that keep data light for patchy networks, support multilingual UI and allow easy geogr...
I’m building a lightweight video-calling application that runs smoothly on both iOS and Android. The initial release is focused entirely on crystal-clear one-on-one calls, so latency, connection stability and efficient bandwidth handling sit at the heart of this project. Users will authenticate exclusively through phone-number verification; no email or social logins are planned for this first phase. A simple, secure workflow—OTP text, automatic read where allowed, and fallback manual entry—will be needed. The interface should feel native on each platform yet share as much code as practical. Whether you prefer Swift with Kotlin, React Native, Flutter, or another modern stack, I’m open as long as the finished product delivers a polished UX and leverages proven r...
Version 1.0 of my SwiftUI app Cut The Line LLC is already on the Store, yet Apple rejected version 1.1 under Guideline 5.1.2 (privacy / tracking). I do not collect or track any user data, so the issue lies in the way my privacy settings are declared. What I need: • Audit the Xcode project (Swift 5, Xcode 15) and ensure any AppTrackingTransparency strings, keys, and data-collection flags are fully aligned with the real behaviour of the app. • Cross-check every data type I selected in App Store Connect and correct anything that might imply tracking. • Prepare a clean, signed build under the existing bundle ID , upload it through Transporter or Xcode, and walk me through the re-submission steps. • Reference the detailed rejection notes I’ll provide so your f...

My web platform is already live and humming; now I want the same experience packaged as native iOS and Android apps. The core features you will bring over include event discovery and multi-type ticketing (QR codes generated in-app), venue booking and management, and a full creator marketplace with enquiry and chat capability. Three role-based dashboards—organiser, venue owner and creator—must mirror the existing web functions while feeling truly mobile. I am comfortable with either React Native or Flutter, provided that Razorpay remains our payment gateway and Firebase continues to handle real-time data, notifications and analytics. You’ll receive Figma screens, brand assets, and detailed REST API documentation the moment we sign the NDA. Beyond the build itself, the s...
I have a fully-formed concept for an iOS e-commerce application and I’m ready to move from idea to App Store listing. I need a developer who can guide the project end-to-end—shaping the user experience, writing clean Swift/SwiftUI code, connecting to the necessary back-end services, and ultimately handling the submission process so the app is live and compliant with Apple’s guidelines. You will start by translating my functional outline into low-fidelity wireframes, iterate into polished UI designs, and then build the production app. Throughout the build we’ll keep each feature shippable, use TestFlight for staged releases, and track issues so nothing slips through the cracks. I’ll provide product requirements and timely feedback; you’ll bring technical...

The scope covers everything from the first line of code to store submission, so I need a developer who can handle design, front-end and back-end work, testing, and deployment in one rapid cycle.

Essential deliverables • Complete, well-structured source code • Builds ready for TestFlight and internal Android...
I want a single, fully-automated application that lets customers in multiple cities book our on-site services—painting, home cleaning, plumbing, and electrician work—while also letting them purchase industrial safety goods that ship from our main warehouse.

Customers will browse services or products, lock in a slot or place an order, pay online, and receive an invoice generated automatically in Zoho Books. As soon as a job is confirmed it should flow to the nearest available Gig Worker, who will see it in real time, accept or reject, navigate to the address, update job stages, add photos, and close the task.

Core expectations • Complete end-to-end build: UX/UI, coding, basic QA, and a ready-to-publish package for both iOS and Android (I’m flexible on native Swift/Kotlin versus a cross-platform stack like Flutter or React Native—use whichever lets you ship fastest without sacrificing quality). • Clean, maintainable code and concise documentation so future iterations are straightforward. • A blazing-fast turnaround; I’m looking to move from kickoff to first test build ASAP.

I need an Android application that allows people to join real-time voice chat rooms, exchange short voice messages, and build public or private groups around shared interests. Every user should have a rich profile (avatar, bio, follower count, etc.) that is visible inside and outside rooms. Access & security Sign-in must happen exclusively through Gmail-based email login, using Google OAuth so the flow stays familiar and frictionless. No phone or other social options are required at launch, though the architecture should leave room for them later.

I’m building a mobile-first fintech app for cab drivers and delivery riders that gives them access to a credit-based wallet. In the first release the wallet must let users draw and spend fuel credits only, yet the codebase has to be flexible enough for us to turn on insurance and utility credits with minimal rework. What I need is the complete product journey: an iOS and Android app for the workers, a slim merchant view so fuel stations can accept payment, and a secure backend that approves credit, settles transactions in real time, and tracks repayments. KYC, instant balance updates, push notifications, and straightforward spending analytics all belong in the core scope. Use whatever modern stack you are fastest with, provided it integrates cleanly with common payment rails and ide...

I need a mobile app that lets users earn real cash by completing missions—starting with the simplest one: watching videos. The flow is straightforward: a user signs in, selects a video task, watches to the end, and instantly sees the reward credited to an in-app wallet that can later be withdrawn to their bank or e-wallet of choice. Core features I have in mind include a smooth task feed, a timer or proof-of-watch mechanism, a secure wallet with withdrawal options, a simple referral code system, plus a small admin panel so I can upload new video campaigns and set reward values on my own. You are free to suggest extra earning mechanics later, yet the first release must focus on the “watch video, earn money” experience and keep everything lightweight for low-end Android de...
An end-to-end mobile commerce experience is needed to showcase and sell physical goods on both iOS and Android. The project covers everything from UI/UX design to secure checkout and order tracking.
