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.

I want to push Granny 1.8.5 far beyond the vanilla experience while still keeping the original APK intact. The core aim is to expand game content, so every change needs to feel like a natural (yet scarier) extension of what’s already there. Scope of the work • Decompile the IL2CPP APK, extract every model, texture, animation and sound, then rebuild the project in Unity so nothing original is lost. • Add two fully playable floors above the current attic—labelled 5 and 6.

What matters most to me is a clean, modern interface that feels effortless on mobile and loads fast even on slower connections.

I’m ready to launch an online store for my fashion and beauty line—think clothing, accessories, and cosmetic items—and I need a developer who can take the project from concept to a live, fully functional e-commerce site. A clean, modern interface, mobile-first responsiveness, and quick load times are non-negotiable because my audience shops heavily from phones. Core functionality I expect: • Shopping cart with smooth, secure checkout • Customer reviews that display star ratings and written feedback • Wishlist so shoppers can save items for later I’m open to what best fits these requirements, provided it supports scalable inventory management and integrates easily with common payment gateways and shipping APIs. Please factor in: – Intuit...
I’m ready to turn a simple game concept into a playable Android prototype and need a mobile-game developer who can move quickly from idea to on-device build. Here’s what I need at this stage: • A runnable Android APK plus complete source files set up in a common engine or native Android Studio project—your choice, so long as it’s easy for me to open and extend. • One short, self-contained level that shows the core gameplay loop with placeholder art and sounds. • Basic UI flow: splash screen, main menu, in-game HUD, pause/restart, and end-of-level summary. • Clean, well-commented code structured for easy future expansion. • Smooth performance on recent mid-range Android phones. I’m flexible on tools—Unity, Unreal, Go...
I need a small, self-contained Android application that runs only on my phone—no cloud, no remote server. The goal is to catalogue dancer profiles so I can show, search, and share them quickly during auditions. Core workflow • Create a new profile with name, age, height, full measurements, and the city the dancer is based in. • Attach multiple photos to each profile (photos are the priority), with the option to add a video clip later. • Browse or instantly search by city; that is my main way of organising the list. • From any profile, tap a button to share it straight to WhatsApp or Instagram without exposing the rest of the database. • Keep everything offline in an on-device database (Room or SQLite is fine). A simple “Backup / Restore&rdquo...

A new health & beauty brand is ready to go direct-to-consumer and the store must feel as clean and calming as the products themselves. The job is to design and configure a Shopify site that keeps the visual language minimalist—ample white space, restrained colour palette, crisp typography—while still guiding shoppers smoothly from discovery to checkout. Core requirements • Theme selection or custom theme that supports a stripped-back, content-forward look on desktop and mobile • Built-in customer reviews on every product page, styled to match the overall aesthetic • Collection and product filtering kept subtle and intuitive (native Shopify options are fine; no heavy apps that bloat load times) • Complete page set-up: home, collections, individual ...
I want to bring a very focused Android app to life: its single goal is to help people relax by letting them browse and play short, soothing sound effects. Think of rain drops, crackling fire, or soft wind—nothing fancy beyond an intuitive catalogue and crisp, uninterrupted playback. Here’s what I need built: an Android application (Kotlin or Java, your choice) whose core functionality is sound playing. The user opens the app, taps a tile or button representing a specific sound effect, and the audio starts instantly. They can pause, stop, or switch sounds without lag. No social networking, e-commerce, or bulky productivity suites—just a clean, lightweight relaxation tool. Deliverables • Complete Android Studio project with well-commented source code • Signe...
I’m putting together a small indie game and need another pair of hands on the development side. Although the form asked about “design help,” what I truly need is practical game-development support—from building core gameplay mechanics and refining level flow to troubleshooting code or integrating art and audio that I already have. The project is still in its early stages, so I’m hoping for someone happy to contribute voluntarily while we shape the prototype. Unity, Unreal, Godot, or another modern engine is welcome; I’m flexible as long as we can iterate quickly and keep version control tidy (Git or Perforce preferred). You’ll have room to suggest features, refactor existing scripts, and generally steer the technical direction. If you like ex...

I want to launch a clean, user-friendly mobile application that lets customers in Saudi Arabia book limousine services directly from their phones. The app’s sole focus, for now, is booking rides. Users should be able to choose between two ride types—single trip or round trip—and confirm each reservation instantly within the app. A seamless, secure payment gateway is essential.

I’m opening a closed beta on Google Play for my new educational app and need 100 real users to join the tester program, download and install the current build, then exercise it for at least a couple of sessions. The insights I’m looking for focus on overall app functionality, so please keep an eye on how smoothly the navigation flows, how quickly each screen loads, and whether any errors or crashes appear.

I’m building a Nirbhay-style flow on my Shopify store where a vehicle owner scans a QR code fixed to the car or bike, pays through a mobile wallet, receives an SMS-based OTP, enters it, and sees an instant “Activated” screen.

I’m embarking on an ambitious project to launch a pair of operating systems — one for mobile devices and one for desktop / laptop computers.

The mobile side will be entirely Custom, so we’re starting from a clean slate and can define the kernel, UI layer, and security model exactly as we want. Here’s the flow I have in mind. First, we’ll specify hardware targets and draft the architecture (kernel type, driver model, boot process). Next comes a minimal viable OS for each platform: the desktop build must boot, recognise core peripherals (storage, networking, disp...
I’m taking my neighbourhood kirana shop online and need a compact e-commerce site that feels effortless on any phone. The core of the job is a modern, clean design that loads fast and makes ordering as simple as walking to the counter. Day-to-day I’ll be adding or removing items as stock changes, so a straightforward dashboard where I can upload photos, prices and quantities from my phone is essential. At checkout we’ll start with a single payment method—Cash on Delivery—yet the flow should still look professional, send order confirmation emails and record each sale in the back-end. Customers may check out as guests or create an account to track past orders; please wire the site so both journeys work without friction. I’m flexible on the underlying sta...
