Cross-platform apps with React Native
One TypeScript codebase for iOS and Android, built with Expo for faster builds and over-the-air updates.
Hire mobile app developers for iOS and Android
TintSol builds iOS and Android apps with React Native and Expo when one codebase fits, and with Swift and Kotlin when the app needs native code. You can hire React Native developers or native iOS and Android developers for a fixed-scope project or an ongoing retainer.
What our engineers build
Work you can hand to this team.
Native iOS apps
Swift and SwiftUI apps for features that need deep platform access, such as background tasks, widgets, or device hardware.
Native Android apps
Kotlin and Jetpack Compose apps that follow Android conventions and handle the wide range of devices in the market.
On-demand and marketplace apps
Customer and provider apps with bookings, live status, and payments, like Makhdoom, our bilingual English and Arabic marketplace for the Gulf.
Push, deep links, and analytics
Notifications, deep-linking flows, and event tracking set up with Firebase so you can see how people use the app.
App Store and Play Store releases
Build pipelines, store listings, review submissions, and staged rollouts handled as part of the work.

How hiring works
From brief to a working team.
- 01
Send a brief
Tell us what you are building, what already exists, and where you need mobile engineers. We reply within one business day with questions or a call slot.
- 02
Get a team proposal
We propose the people and roles the work needs, and whether a fixed-scope project with milestones or an ongoing retainer fits better.
- 03
Onboard
The team gets access to your repositories, tools, and environments, reads the existing code, and agrees working hours, channels, and a definition of done with you.
- 04
Ship on a set cadence
Work runs in short cycles with a planning session, regular demos, and written status updates, so you always know what shipped and what is next.
FAQ
Questions we hear first.
Should I build with React Native or go native?
React Native is the right default for most product apps because one codebase covers both platforms. We recommend Swift and Kotlin when the app relies heavily on device hardware, background processing, or platform-specific UI, and we explain the trade-off in the proposal.
Can you build apps in Arabic as well as English?
Yes. We build bilingual apps with right-to-left layouts, as we did for Makhdoom, an on-demand marketplace for the Gulf.
How quickly can a team start?
Most engagements start within 5–7 business days of the initial brief. We reply to every enquiry within one business day, and the start date depends mainly on how quickly scope and the contract are agreed.
How do you work across time zones?
We agree a daily overlap window before work starts. Our Lahore team works on Pakistan time (UTC+5), one to two hours ahead of the Gulf, so Gulf clients share almost a full working day, and our Riyadh office is on Saudi time. UK and EU clients typically share their morning with our afternoon; US clients get a shorter window in their morning plus a written handover at the end of our day.
Who owns the code?
Code ownership is agreed in the contract before work starts. The code lives in repositories you can access from the first day, so you can see every commit as it lands.
