Mobile Apps
Mobile App Development Company
RedZen is a mobile app development company that takes a business app from idea to the App Store and Google Play — design, build, backend, testing and launch, with one senior team the whole way and a fixed price agreed before work begins.
iOS + Android
Native or cross-platform, whichever fits your budget and timeline.
Fixed price
Cost and delivery date agreed before we start — never hourly.
Store launch handled
Builds, signing and submission to both stores are our job, not yours.
Why business apps stall
A freelancer who disappears mid-build, leaving an app no one can finish.
An agency that overbuilds a bloated v1 that costs a year and ships late.
A prototype that works in a demo but cannot survive real users or the store review.
No one who owns the App Store and Google Play submission, so launch drags for weeks.
One senior team scopes a focused first release, builds it properly on both platforms, and handles the store launch — so you get a live, maintainable app instead of a stalled project.
What you get
iOS & Android
Native builds for each platform, or one cross-platform codebase when that fits your budget and timeline better.
Design included
We map the flows and design every screen, or build from designs you already have. See app design.
Backends & APIs
We build the server side too — accounts, data, payments — or connect cleanly to systems you run.
Store launch
We handle builds, signing and submission to the App Store and Google Play so the launch is not your problem.
Built to last
Sensible architecture and testing so the app stays maintainable as it grows, not a rewrite in a year.
Senior, accountable
A studio you can reach, not a freelancer who may vanish — continuity for an app that matters to the business.
Apps live in the stores
We ship our own apps to the App Store — Aether, Tafaseer and CaliTrack are RedZen builds — so store review and real-device release are routine, not a first for us.
- A mobile app on iOS, Android, or both
- The design and the backend or API it needs
- Test builds (TestFlight / Play internal testing)
- Source code and the published store listings
How we work
Scope
We agree the core feature set for a first release worth shipping — focused, not bloated.
Design
Flows and screens so you can feel the app before a line of code is written.
Build
Development in testable increments, with builds you can run on your own device.
Launch
Real-device testing, store submission, review handling and go-live.
Hire mobile app developers
If you need to hire mobile app developers rather than assemble and manage a team, RedZen is the alternative: one senior team that covers iOS, Android, design and the backend, engaged on a single fixed-price agreement instead of per-head contracts.
You get the continuity of an in-house team without the hiring, onboarding, or bench cost — and the code and store listings are yours to keep.
Enterprise mobile app development
For an established business, a mobile app usually has to fit existing systems — accounts, data, an ERP or CRM, single sign-on — not stand alone. We build the app and the integrations together, with the security and maintainability an internal tool needs to survive past launch.
The result is an app your team and customers can rely on, built to be handed over and extended rather than rebuilt.
Common questions
What is mobile app development?
Mobile app development is the design, build, testing and store launch of an application for iPhone or Android. See our guide on whether your business needs an app for the informational version.
How much does it cost to develop a mobile app?
It depends on scope, so we give a fixed price after a short scoping conversation — the cost and delivery date are agreed before any work begins, and neither moves. We never bill hourly.
How do I choose a mobile app development company?
Look for a senior team you can reach directly, real apps shipped to the stores, ownership of the code, and a fixed price rather than open-ended hours. We answer this in full on the blog.
How do I hire mobile app developers?
You can hire individually and manage them, or engage one senior team like RedZen on a fixed-price agreement that covers iOS, Android, design and backend — no hiring or bench cost.
Should I build native or cross-platform?
For demanding apps we lean native; for a tighter budget that needs both platforms, cross-platform can be the smart call. We talk through the trade-offs honestly for your case rather than defaulting.
Do you build for both iOS and Android?
Yes — either or both. Many clients start on one platform to validate, then add the second once the app is proven.
Do you handle the App Store and Google Play submission?
Yes. We manage builds, signing, store listings and the review process end to end, so launch is handled for you.
Can you take over an existing app?
Often yes, after a short code review to understand its state and what it needs.
