The ultimate guide to building a mobile app
Got a great idea for an app? Need a new way to grow your business? We tell you everything you need to know about building a mobile app in 2020.
Mobile App Development is the creation and development of phones, tablets, personal digital assistants, and other devices that have operating systems. It involves creating software applications for the devices, such as games, utilities, and sometimes even simple to-do lists. These applications are created using programming languages such as HTML5 and JavaScript, which allow developers to create a good user interface. Mobile App Development requires both specific and hard skills from developers, from debugging existing applications to creating entirely new ones.
A great benefit of having a Mobile App Developer on your side is the knowledge and experience they can provide to make your business grow. In addition to creating mobile apps that are good for the user experience, Mobile App Developers can help you with backing up the data from your application securely, modifying an existing app to meet new requirements, troubleshooting any current issues in your application, setting up a server for your application and so much more.

From 380,372 reviews, clients rate our Mobile App Developers 4.9 out of 5 stars.I’ve started building a sports-focused mobile application in Flutter and now need a creative UI/UX specialist to bring the interface to life. The core audience is athletes, so every screen should feel performance-oriented, data-driven, and quick to navigate even when they’re on the move or mid-training. What I expect from you: • A full set of production-ready Flutter widget screens that cover onboarding, dashboard, detailed activity pages, and any ancillary flows we identify together. • Consistent use of modern design patterns, thoughtful micro-interactions, and a colour palette that resonates with competitive users. • Pixel-perfect implementation in Flutter (no separate mock-ups that then have to be rebuilt). I’ll supply the functional requirem...
Hazırda həm iOS, həm də Android üçün inkişaf etdirilən bir mobil tətbiqin tam vizual kimliyini yaratmaq istəyirəm. Əsas funksional axın – istifadəçi qeydiyyatı – maksimum rahat və intuitiv görünməlidir, buna görə login, qeydiyyat, profil tamamlanması kimi ekranların hər detalına xüsusi diqqət yetiriləcək. Rəng palitrasını, şriftləri və istinad nümunələrini moodboard şəklində təqdim edəcəyəm və iterativ geri-bildirim dövrü ilə işləyəcəyik. Sənə etibar etdiyim digər məqamlar: • Wireframe-dən yüksək dəqiqlikli mockup-a qədər bütün ekranların hazırlanması • Figma (istəyə görə Sketch) mənbə faylları və kliklənə bilən prototip • Komponent kitabxanası, həm iOS Human Interface Guidelin...
I already have a live Flutter app and an active AdMob account. I now want Google AdMob Native (In-Feed) ads woven into my main listing feed, very similar to the way OLX sprinkles promotions between items. Here’s the flow I’m aiming for: after every five feed items a native ad should appear, matching the app’s current look and feel so users experience it as part of the content rather than a banner. I do not yet have the specific Native ad-unit ID, so I’ll need you to walk me through creating it in the AdMob console and wiring it up in code. The project is straightforward: plug the Google Mobile Ads SDK into my existing Flutter codebase (Dart), build a widget that pulls and renders the Native ad, place it in the list adapter, then verify that test ads show up reli...
I need a developer who can take our existing whole-home scent diffuser hardware and give it a fresh, branded mobile experience on both iOS and Android. The current units already pair over Bluetooth and can switch to Wi-Fi once configured; the new app must replicate that connectivity, then layer in a cleaner interface and a few extra smarts that set us apart from the generic software we use today. Core features we have in mind: • Customizable scent schedules that let users pick days, times, and intensity levels • Real-time usage statistics so homeowners can see oil consumption and filter life at a glance • Full remote control—start, stop, boost, or mute a diffuser from anywhere once Wi-Fi is enabled The firmware and protocol documentation are ready, and I can su...
I need a fully featured casino experience that launches simultaneously on Android and the web. The core catalog should open with two classic options—slot games and card games—plus a cricket-themed title to appeal to our local fan-base. Real-time play is essential, so the architecture must support live multiplayer tables and rooms with low-latency communication. Players must be able to transact seamlessly through in-app purchases, and talk to one another via integrated text chat during matches or spins. A single-codebase approach (e.g., Unity, Flutter, or similar) that compiles cleanly for both targets is preferred, provided the final builds feel fully native on each platform. Back-end services need to handle secure user accounts, RNG-verified game logic, payment processin...
Project Goal Build a mobile-first digital payments app that allows users to send, store, convert, and spend crypto-backed USD with extreme simplicity, comparable to Zelle or Venmo — while crypto remains largely invisible to the user.

I have two signed Android APKs that share the same brand: a Chinese-language build that already handles user registration smoothly, and an English-language build that currently lacks this flow. My goal is to extract every user-management API call from the Chinese APK—endpoints, headers, payload structures, encryption or signing logic—and transplant that functionality into the English APK so both variants register users in exactly the same way. What I can provide: • The release APKs for both language versions • Valid test accounts and server access for live registration checks • Any additional assets the Chinese build relies on (native libraries, certificates, config files) What I need from you: • Decompile, inspect and document the Chinese APK (jadx, a...
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 looking to develop a language learning app focused on speaking practice for advanced learners.

I need a sharp-eyed Flutter / Node.js troubleshooter to pinpoint and fix an intermittent signup failure in my mobile app. The OTP step completes successfully, yet many users (on both iOS and Android) hit a wall when the form tries to create the account. No explicit error is returned to the UI, but the account never appears in the database. Here is what I can share right away: • Front end: Flutter 3.x, using MSG91 for phone-based OTP. • Back end: Node.js (Express) REST API, MongoDB. • Flow: user enters phone → receives OTP → OTP verified → form posts profile details → failure occurs after the POST. What I need from you is a fast, reproducible diagnosis, a clean code fix (whether in Dart, the REST endpoint, or both), and a short hand-off note so my te...
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...
I want to bring a brand-new social networking idea to life on Android. The concept, user flows, and core screens are already sketched; now I need a developer who can turn them into a polished, production-ready app. Here’s the outline of what I’m after: • Full Android build in Kotlin (Java is acceptable if you have strong reasons). • Standard social features—secure sign-up/login, user profiles with photos, a simple post feed, likes/comments, and real-time chat or messaging. • Cloud-based back-end: I’m leaning toward Firebase for authentication, Firestore/Realtime Database, and push notifications, but I’m open to alternatives if you can justify them. • Clean architecture, modular code, and clear naming so another dev can jump in later if nee...

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...
I own a licensed copy of the Dooo Movie Streaming Android source code and now need it running live on Google Play. The current project refuses to compile because of dependency issues and an outdated SDK. Here’s what I need from you: • Open the project in Android Studio, upgrade it to the latest stable SDK/Gradle versions, and cleanly resolve every dependency conflict so the APK builds without warnings. • Configure package name, signing key, Firebase/Ad-mob (if present in the code), and any other runtime settings the template requires. • Run a full device/emulator test to confirm login, streaming, search, and push-notification flows all work exactly as in the template demo. • Generate release AAB/APK and guide me through—or directly handle—th...
I'm looking for an experienced app designer for IOS and Android, to help redesign my existing app. The goal is to improve usability and add new features.

I’m ready to move forward with a project that pairs a full-featured Android app with a matching website. The core requirement both share is secure, reliable user authentication—think sign-up, login, password reset, and the usual account-management flows. Everything else about the product’s purpose, design language, and long-term roadmap is still flexible, so I’d like to refine those details together once you’re on board. I don’t have a fixed technology stack in mind; whether you prefer Kotlin in Android Studio, Flutter, React Native, or another modern framework on the mobile side—and Django, Laravel, Node.js, or something cloud-native on the web side—I’m open to your recommendations. What matters most is clean architecture, maintainabl...
We need a Unity developer to build a WebGL configurator (URP) for yachts.

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...
I need a clean, modern website where I can publish my dealership’s vehicles, attaching multiple photos and a video to every listing without fuss. The entire experience must feel seamless on a phone—image galleries should swipe smoothly, video playback must be instant, and buttons and forms have to fit comfortably on any small screen. Key points I care about: • A straightforward back-office that lets me add, edit or remove vehicles and drag-and-drop both photos and videos (common image formats + MP4 or YouTube/Vimeo links). • Lightning-fast, mobile-optimised front-end with clear calls to action for potential buyers. • Clean code and a framework or CMS that makes future updates easy for someone non-technical. • Final hand-off on my server, plus a quick ...

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’m ready to move my site () from Divi 4 to the current Divi 5 beta and would like a specialist who can handle the upgrade smoothly while giving the design a subtle but noticeable facelift. Here’s what I need done: • Build the entire site (all pages) on Divi 5 beta, setting up a child theme renamed to “TRsites.” • Recreate every page using global settings wherever possible—primary and accent colours, typography, header, and footer all controlled from one place. • Retain all existing images exactly as they are while introducing modern, sleek fonts, more whitespace, and an overall cleaner, templated look. • Ensure the layout is 100 % mobile-responsive; I want it to look spectacular on phones and tablets, not just desktop. • Lev...

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...

Drivers should be able to enter delivery quantities and basic details, supervisors should be able to verify entries and manage site-level...
I’m building a small bionic butterfly that “flips” in mid-air, powered by an ESP32-S3 Super Mini. What I still need is the full control system: firmware for the board plus a cross-platform mobile app that drives two micro-servos through a joystick interface. Here’s the flow I’m picturing: • The ESP32-S3 runs custom firmware (Arduino IDE or ESP-IDF—whichever you prefer) advertising itself over BLE. • The mobile app—working on both Android and iOS—connects, shows a virtual joystick, and streams position data in real time. • The board translates that data into precise PWM signals so each servo can beat the wings smoothly and synchronously. I will supply the hardware (ESP32-S3 Super Mini and servos) for your testing if nee...
