Product scoping
We start with who the app is for, which OS they use, and what v1 must do — not a stack logo slide.
Home / Mobile App Development
iOS, Android, and cross-platform — scoped before we build
Mobile App Development Services
Mobile app development for startups and businesses: we agree the platform, features, and store requirements first. Our public portfolio is web; mobile work is planned per engagement. India-based team, worldwide clients.
How we approach mobileWhat this
What this
covers
An overview of mobile work. Android, iOS, and cross-platform each have their own page.
Start this engagement
Android or iOS first
When budget forces a sequence, we help you pick a first store based on your users, not a résumé.
Cross-platform when it fits
A shared codebase is a choice after we know the UI and device features. It is not automatic.
API and backend
Mobile apps need a server. We can plan that API with the same Node.js approach we use on web products.
Interface design
Mobile-width UX is part of scoping. Native UI conventions are agreed before visual polish.
Store submission
We plan for Play Store or App Store requirements as part of the project, not as a surprise at the end.
Why FastUI Labs
Why FastUI Labs
Honest about what is live today versus what we will scope with you.
Web proof, mobile by engagement
Our five public case studies are websites and web applications. We do not invent native apps that are not in the portfolio.
Same product discipline
Discovery, planning, design, development, QA, launch — the same six steps as our web work.
No fake stacks
We will not list Kotlin, Swift, or Flutter as shipped expertise until that work is public.
Backend we have shipped
If the app needs accounts, payments, or maps, we already do that class of API on the web.
Clear recommendation
Native vs cross-platform is a decision, not a slogan. We will say when a mobile web app is enough.
Worldwide clients
India-based team, English-language delivery.
Process
How we build mobile apps
Mobile uses the same six steps. Platform and store details are decided in planning.
Discovery
We learn the users, devices, and jobs the app must do.
Planning
We choose Android, iOS, both, or cross-platform, and what is in v1.
UI/UX Design
We design the mobile flows before committing to a framework.
Development
We build the client and the API the scope includes.
Testing & QA
We test the agreed flows on devices we have access to. No invented device lab.
Launch & Support
We help with store submission and stay available for the next release.
Technologies we use
Modern tools we use to design, build, and ship reliable digital products.
FAQFrequently Asked
Frequently Asked
Questions
Straight answers about scope, process, timelines, and how we work with clients worldwide.
The public case studies are websites and web applications. Mobile app work is scoped per project. We will not present a web product as a native app.
Discovery, platform choice, UI, the application itself, and the API it needs. Store listing work is part of launch when you want us to submit.
Often yes, if the job can be done in a browser. See web development and web application development. We will say if a store app is not justified yet.
Yes. FastUI Labs is based in India and serves businesses worldwide.
