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 381,948 reviews, clients rate our Mobile App Developers 4.9 out of 5 stars.I need a location-based geofilter activated on Snapchat for a single venue that serves as our community’s main gathering place. I already have the design concept sketched out; what I’m missing is the technical side—preparing the artwork to Snapchat’s specs, defining the exact geofence around the venue, submitting the filter through the On-Demand dashboard, and confirming it goes live without hiccups. Here’s what I expect from you: • Refine or recreate the artwork so it meets Snapchat’s PNG size, transparency, and resolution requirements. • Configure the geofence precisely around the landmark (I will share the map pin and radius). • Schedule the filter for the dates and hours I provide, submit it, and keep me updated until Snapchat app...
My Android app is finished and I’m ready to see it live on the Google Play Store. I need someone who can take the build I provide (AAB or APK), walk it through every Play Console step, and make sure the first production release is approved without hiccups. What I will hand over: the signed build, app icon, screenshots, description text, privacy-policy link, and any other assets you need. What I expect back: • A properly configured Play Console listing with all metadata completed • Correct bundle signing, versioning, and compliance checks (target SDK, 64-bit, Data Safety, etc.) • Internal test track upload to confirm install, followed by staged rollout to production • Clear notes so I can repeat the process for future updates If you notice anything tha...
My live app on both iOS and Android suddenly stopped talking to its companion website. All users now see loading errors where content used to appear. I haven’t changed the code or any server settings, and I’m not even certain what the original developer used to build the backend—WordPress, a custom stack, or another CMS are all possibilities. What I need is straightforward: diagnose why the mobile clients can’t reach or authenticate with the site anymore and implement a solid fix so content loads normally again on both platforms. You will likely inspect API endpoints, SSL certificates, DNS, hosting logs, or any middleware in the path, then patch or re-configure whatever is blocking the handshake. Once the app is successfully pulling live data on iOS and Androi...

I’m building a mobile app whose sole focus is accurate astrological calculation and prediction. Users will enter their birth data and instantly receive personalised horoscope forecasts generated by an in-app calculation engine. The app must handle ephemeris look-ups, house and aspect calculations, then transform those results into clear predictive text that can be displayed in a clean, modern UI. The core I need from you is the algorithmic backbone—think Swiss Ephemeris-level precision—wrapped in a stable cross-platform shell (Flutter or React Native are both fine; if you have a better suggestion, let’s discuss). While the initial launch centres on horoscope predictions, the architecture should be flexible enough to accommodate future add-ons such as zodiac compati...
We have released a maintenance update to the current internal build of the Golf Club Operations Platform. This update focuses on improving reliability and addressing several minor issues identified during daily staff use. The aim is to make the existing version more stable while we continue developing the expanded web and mobile system. ### Fixes & Improvements **Authentication & Access** * Corrected role permissions so staff now only see modules assigned to their role. * Improved session handling during file uploads. * Fixed the password reset activation link not completing in some cases. **Event & Trophy Records** * Resolved intermittent photo upload errors on mobile devices. * Fixed occasional duplicate entries in trophy history. * Improved saving of event winners to en...

Would like notifications enabled etc and subscriptions to premium so user doesnt see ads, verified creators that get a blue verified star as one of purchase and creator boosts which are like ads that get their content to the front of the line
I’m building a single platform that serves four distinct roles—tenants, owners, property managers and system administrators—each seeing only the information and tools relevant to them. Tenants must be able to: • Pay rent online through an integrated, secure gateway • Submit and track maintenance requests in real time • View current and past lease agreements whenever they need them • Able to view and pay the utility bills e.g. electricity, property tax. Owners should have a dashboard where they can: • Access up-to-date financial reports • Add, edit or archive their own properties • Communicate directly with their tenants from inside the app • View the status of utility payments by tenants. Property managers will need c...
I need a lightweight chat-style messenger built specifically for Android so I can read incoming messages and send quick replies from the same screen. At this stage I only require the core one-to-one text conversation flow; once that is solid I may extend it to voice notes, file exchange, or group rooms, but those extras are not part of this first milestone. Here is what I expect: • A clean Android Studio project written in Kotlin (Java is fine if you strongly prefer). • Real-time send/receive with message status indicators. You are free to choose Firebase, WebSockets, or any other modern backend you are comfortable with—just keep the setup clear so I can run it locally. • Simple authentication (email/password or phone OTP) so users can log in and start chatting i...
I’m ready to move my physical-goods business onto a full-scale digital storefront that feels as smooth and trusted as Amazon, but is entirely branded for us. The core build must include three essentials baked in from day one: a frictionless shopping cart, secure customer account creation, and a robust product-review system that encourages repeat purchases and community trust. Because every item ships from our own warehouse, the platform needs native support for in-house delivery workflows—think real-time inventory, pick-pack-ship dashboards, driver assignment, and order-status updates visible to the customer without leaving the site or app. Expected deliverables • Responsive web storefront (React, Vue, or equivalent) • Companion iOS and Android apps sharing ...

I am building an AI-driven solution that lets takeaway and restaurant staff see incoming orders in real time, have those orders routed intelligently to the right driver, and record the exact cash or card amount collected on every drop-off without anyone keying numbers in by hand. The system must run seamlessly as both a web application for the restaurant dashboard and a companion mobile app that drivers carry on the road. Core workflow • Orders arrive from the POS or online channel and appear instantly on the web dashboard. • A routing engine evaluates driver location, capacity, and estimated delivery time, then assigns the job automatically. • When the driver marks the delivery complete in the mobile app, the order status closes and the cash balance for that run is log...
I need a speech-to-text application that operates on both iOS and Android platforms. The app should support English for speech recognition. Ideally, when user hits specific physical device button combination, the app will take over the “text input” underlying OS routine and a pop-up will come up From there, speaker is on, and user dictates what needs to be typed. It shows real time what user is “saying” through device built in microphone and shows text within the popup. User can then choose to edit the text using standing keyboard interface … OR… hit OK. Front there, the “text” is passed back to original OS routine (which for interrupted) and ENTRR button with is automatically hit
I need an app developed for both iOS and Android platforms that converts my existing Excel spreadsheet program.

I’m expanding an in–house mobile application that lets users register, track, and manage their physical payment cards from one place. The codebase is already in Flutter, and I want to keep the momentum going with a senior-level developer who is comfortable applying Clean Architecture and true Domain-Driven Design principles. What you’ll be diving into • A cross-platform Flutter project that must compile flawlessly on both iOS and Android. • Refactoring existing modules to align with layered, testable architecture. • Building new card-management features (activation, balance fetch, transaction lists, in-app notifications). • Integrating secure REST/GraphQL APIs, local persistence, and state management (preferably Riverpod or Bloc). How we&rsqu...
I’m ready to launch a basic yet scalable digital platform where homeowners can browse local handyman services. I’m flexible on whether this should start life as a responsive website or a dedicated mobile app; if you recommend the latter, it must run on both iOS and Android from day one. Core scope • Service listings are the only mandatory feature right now—clean categories, search, location-aware results and an easy way for me to add or update providers from an admin panel. • I want solid foundations so future modules such as booking calendars or user ratings can slot in without rewriting the whole codebase. What I’d like from you 1. A brief tech-stack rationale (e.g. React / , Flutter, React Native, Laravel, Node, Firebase—use what you&rs...
​"In a Zero-Trust DePIN environment, how do you ensure the 'Integrity of Result' from an untrusted provider? If the computation happens inside an AMD SEV-SNP enclave, how do you architect a 'Remote Attestation' flow that proves to the client the data was processed by the correct binary without exposing the client's raw input to the provider's OS?"
​"We are dealing with a real-time stream of 100,000 packets per second. If the user triggers a complex filter on a 10-million-record heap, how do you prevent Main Thread 'Jank' (frame drops) while maintaining a 60FPS UI? Specifically, how would you handle memory management to avoid Garbage Collection spikes?"
I have already wrapped my website in WebView projects—one in Android Studio and one in Xcode—and completed most of the groundwork. Certificates and provisioning profiles for both stores are in place. What’s holding me back from submitting is a round of final adjustments on both iOS and Android so the builds meet App Store and Google Play guidelines. I’ll send you the existing Android Studio and Xcode projects immediately. Your job is to refine any layout quirks, loading indicators, splash screens, or minor styling inconsistencies that could trigger a rejection. After that, compile release-ready builds (AAB for Google Play and an IPA or Xcode archive for the App Store) and return the updated source. Deliverables • Polished Xcode and Android Studio projects ...
Project Title Desktop App for Automated Surgical Video Editing (MVP – Video Processing) ⸻ Project Description I am a surgeon developing an innovation project focused on surgical education. I am looking for a developer (or small team) to build the MVP of a desktop application called SurgeCut, designed to automatically condense long laparoscopic surgery videos into short educational highlights. ⸻ Project Context Laparoscopic surgeries are recorded in full (1–6 hours), often split into multiple video files totaling 1–5GB (HD or 4K). Manual editing is time-consuming and inefficient. The goal is to create a desktop app that: • Merges multiple video files automatically • Detects low-activity moments (“dead time”) • Removes those segments ...

I’m ready to launch a full-scale adult live cam platform focused on real-time streaming. The core experience must let viewers watch models broadcast live with minimal latency, so a modern WebRTC or HLS set-up that can handle thousands of concurrent sessions is essential.

Think recurring subscriptions for premium, pay-per-minute private sessions, and a flexible tipping ...
I’m building a complete digital-health backbone that lets clinicians and patients connect seamlessly by phone or tablet while handling all billing inside the same experience. The mobile app must launch on both iOS and Android from a single codebase if possible, giving users identical functionality on either platform. Core communication features include: • real-time video consultations that feel as smooth as popular conferencing tools, • secure text chat for follow-up questions, and • file sharing so results, images, or prescriptions can move instantly between parties. For payments, I want a proven third-party gateway (Stripe, PayPal, or a similarly trusted provider) wired directly into the app. Patients should be able to settle consultation fees in-app with...
I’m building a mobile application that guides users through their personal health-recovery journey. The vision is a clean, motivating space where people can set goals, log daily progress, and see their improvements over time. I’m still refining the final feature list, so I want a developer who can both advise on best practices and then turn the agreed scope into a reliable, cross-platform product. What the project needs • A polished iOS and Android build (React Native, Flutter, or native—open to your recommendation) with secure user accounts, cloud data storage, and push notifications. • An intuitive onboarding flow plus a dashboard that lets users record activities and track milestones with ease. • Clear, well-commented code and brief documentation ...
I need an Android app that lets me film a commercial train wagon and, in real time, capture its key data. While the camera is rolling, the app should log the wagon’s details, pull any identification numbers or labels it detects, and give me a quick way to note its visible condition and maintenance status. Think of the smooth, guided workflow used in QCR-style inspections—tap to confirm, swipe to move on—only tuned for rolling stock. As soon as I finish recording, a neatly laid-out A4 PDF must be produced automatically. One wagon per page, with a frame grab of the video, the captured fields already filled, and space left for handwritten or typed comments. The PDF has to save locally and be shareable through the Android share sheet, ready to print without scaling issues. ...

I’m reaching out to get some advice regarding a mobile app project I developed back in 2020 — Hola Rider and Hola Driver, originally built for the Sri Lankan market. The system includes the driver app, rider app, booking website, driver registration portal, and a full admin dashboard. The project was about 90% complete and at the testing stage, but due to COVID we had to pause everything. At that time, I stopped the Azure server and related subscriptions. I still have all the source codes and assets. The apps were developed using React Native for both iOS and Android, and React JS for the website and affiliate portals. The Admin Panel features include: • Dashboard with daily/monthly registration stats and graphs • Agent details (affiliate marketers/stakeholders) &b...
I need a bespoke inventory management system that sits on a cloud-based database and is accessible from web, mobile, and desktop interfaces. The core workflow is straightforward: record quantities of materials as they arrive on site, let each team log usage in real time, and then surface the data through clear, filterable reports. Access will be split between two levels—admin and standard users—so the application must include a simple yet secure role switch along with audit logging of every stock adjustment. Because we operate in the field, speed and offline resilience on mobile are important. I’m happy with any stack you are comfortable with, provided the back end is robust, well-documented, and future-proof. Deliverables • Fully functional cloud-hosted d...

I have an internal voter-engagement app already running on AppSheet that holds roughly 175,000 records. Ten team members use it today, and I expect that number to reach about 500 over the next twelve months, so stability and performance at scale matter. The next phase of work focuses on three areas: • Data & workflow upgrades – Revamp the existing forms to capture mobile numbers and related voter details more quickly and accurately. – Build advanced reporting and analytics views so campaign managers can see real-time progress without exporting to external tools. – Strengthen user-level access controls to keep sensitive data visible only to the right internal audiences. • Interface polish – Streamline navigation so first-time users ca...
I’m building a new mobile app that helps users organise and complete remote tasks, and I need a cohesive set of realistic illustrations that will give the interface a polished, trustworthy feel. Each illustration should align with common in-app moments—onboarding screens, empty states, success messages, and quick tutorials—so users intuitively understand what to do next. Here’s what I have in mind: • Consistent style: clean, realistic visuals (no cartoon exaggeration) with a balanced, modern colour palette that translates well on both light and dark themes. • Mobile-first sizing: SVG or high-resolution PNGs optimised for scaling across multiple screen densities. • Seamless hand-off: layered source files in Adobe Illustrator or Figma so my deve...
