iOS + Android
We design and build cross-platform mobile apps for startups and small businesses in the US, UK, Canada and Australia. You get a fixed price before work starts, a written MVP scope, about 7 weeks to the stores, and the code and store accounts in your name.
Quick answer
At WebStackRank a cross-platform iOS and Android MVP costs from USD 4,500 (≈ GBP 3,402, ≈ EUR 4,016) at a fixed price. It includes sign-up and login, a REST API, push notifications and App Store and Google Play submission, and goes live in about 7 weeks. Payments, admin panels and integrations are priced line by line in the proposal.

Typical published estimates start in the tens of thousands of dollars because they assume two native apps, a multi-person agency team and an open-ended scope. We build one React Native codebase, write a tight MVP scope before any code, and work as a small founder-led team with no sales layer and no US or London office rent. You get a first version that does a few things well. When you need more, every extra feature is priced up front.
A minimum viable product is the smallest version of the app that does its main job well enough for real users to rely on it. Version 1 should have one core job (book a slot, log a visit, order a product, track progress), the screens that job needs, sign-up and login, notifications that bring people back, and nothing else. For most apps that is 8 to 12 screens.
Everything you are unsure about (referral programmes, social feeds, complex settings) waits for version 2, when usage data tells you whether it is worth building.
Yes. We build one React Native codebase that ships as a native app to both the App Store and Google Play. For bookings, marketplaces, member apps, field tools and most business apps, users cannot tell the difference, and you maintain one codebase instead of two.
Native development is the better choice for heavy 3D or games, advanced augmented reality, long-running background audio, and watch or car apps. If your idea depends on one of those, we will say so before quoting.
Stack
We build in React Native, and here is why. It produces real native interfaces on both platforms from one codebase, it shares a language (TypeScript) with the web dashboards and APIs we build around it, and it has a large pool of developers, so you are never locked in to us. Flutter is a capable alternative with its own rendering engine; fully native Swift and Kotlin apps give the deepest device access at roughly twice the build and maintenance effort.
| Option | Strength | Trade-off |
|---|---|---|
| React Native (what we build) | one TypeScript codebase, native UI, shares code with web | very device-specific features may need native modules |
| Flutter | consistent custom UI on every device | Dart language; separate from your web stack |
| Native (Swift + Kotlin) | full device access and platform polish | two codebases to build and maintain |
Process
We work remotely across time zones: live calls in your morning or our evening, and written updates and test builds in between, so the work moves while you sleep.
Yes. Most apps need a server: user accounts, data, notifications, payments and an admin panel where your team manages content and customers. We build it on Laravel or Node from USD 3,500, or connect the app to an API you already have. See custom web application development.
Payments
It depends on what you sell. Apple and Google generally require their own in-app purchase systems for digital goods and subscriptions used inside the app, and take a commission. Physical goods and real-world services, such as a delivered product or a booked appointment, can usually be paid with a provider such as Stripe. The store rules change, including in the US, so we check Apple’s and Google’s current guidelines for your exact model at scoping and write the chosen approach into the proposal.
Both stores require you to declare what data the app collects: Apple’s App Store privacy details and Google Play’s Data safety form. We fill them in from what the app actually does, add in-app consent where GDPR or UK GDPR applies, and include a privacy policy link and an account-deletion option, which both stores expect for apps with accounts. We prepare the submission so review questions are answered before they are asked.
Apps that handle protected health information need extra care under HIPAA; talk to us before scoping one, so hosting and vendors are chosen for it from the start.
We list app types, not industries we claim to know: the scope is written around your business, whatever sector it is in.
We haven’t published a mobile app case study yet, so we won’t show you mock-ups dressed as client work. Our published case studies are web platforms we built and run ourselves (see the portfolio). Our app portfolio is available on request, and on a call we walk you through our process, scope template and a sample proposal.
Hiring
| Option | How you pay | Best when | Watch out for |
|---|---|---|---|
| Hourly freelancer | by the hour | small fixes, a known developer | availability, handover, no QA |
| Staff augmentation | monthly per developer | you have a product manager and tech lead | you manage the work and the risk |
| Fixed-scope studio (us) | fixed price per written scope | you want a finished app and a known cost | changes become new priced lines |
About 7 weeks for the MVP after the scope is signed. What moves the date: the number of screens and user roles, integrations with other systems, how quickly designs and content are approved, and store review, which usually takes days but can take longer for a first submission.
Expect a few running costs: the Apple and Google developer accounts, hosting for the API, and any third-party services such as SMS, email, maps or payments. Apps also need updates when Apple and Google release new OS versions. Support after launch is written into the proposal; after that, updates and new features are fixed-price blocks, with no retainer.
About us
WebStackRank is a founder-led studio in Dubai. Muhammad Waleed, founder and lead developer, scopes every project (LinkedIn). We have no US or UK office or entity; we work remotely, with contracts and a written scope, 50% to start and 50% at launch. Businesses in the UAE can see our mobile app development in Dubai and the UAE page.
You do. The Apple and Google developer accounts are opened in your name, the repository can live in your GitHub from the first commit, and the code transfers in full on final payment. We never publish your app under our own developer account.
