Products & ventures
We're product builders, not just a service provider
We invest in and operate our own mobile apps. It keeps our instincts sharp — and means we feel your users' pain firsthand.
How we work
A clear path from idea to launch
A proven, transparent process. You always know what's happening, what's next, and why.
- 01
Discovery
We align on the problem, users, and success metrics — then pressure-test scope so we build the right thing first.
- 02
Planning
Architecture, roadmap, and a clickable design direction. You leave with a clear plan and a realistic timeline.
- 03
Development
Weekly shippable increments in React Native, with backend and AI built in parallel and visible progress every sprint.
- 04
Testing
Automated tests, device-lab QA, and beta builds via TestFlight and Play Console to catch issues before users do.
- 05
Launch
Store listings, review submission, and a coordinated release. We handle the App Store and Play Store end to end.
- 06
Support
Monitoring, iteration, and a maintenance plan that keeps your app fast, current, and ahead of OS changes.
Why MobileDevSimplified
A partner that thinks like a founder
We pair deep React Native expertise with a real product mindset — and we stick around for the long haul.
Deep technical expertise
Senior engineers who live in React Native and Expo — performance, native modules, and the gnarly edge cases included.
A product mindset
We operate our own apps, so we obsess over outcomes and UX, not just tickets. We'll tell you what not to build.
Startup speed
We've shipped under real deadlines and constraints. Weekly increments, fast feedback, and momentum from week one.
End-to-end delivery
Design, mobile, backend, AI, and store launch under one roof — no hand-off gaps, no finger-pointing.
Long-term partnership
Most of our work is repeat work. We optimize for relationships and maintainable code, not one-off projects.

Testimonials
Teams keep coming back
The clearest signal we're doing it right: founders and engineering leaders who choose to work with us again.
“They shipped our wallet faster than we thought possible — and the code was clean enough that our team could own it afterward.”
“It felt less like an agency and more like a founding engineering team. They pushed back on scope and saved us months.”
“Their engineers embedded into our team and immediately raised the bar on our React Native architecture and release process.”
“Offline-first is hard. They made it look easy and our field teams finally trust the app in the middle of nowhere.”
Let's build something people keep on their home screen.
