What we do
When an app has a lot of animation, the camera, NFC or bank-grade security, we write two native apps in Kotlin and Swift. When the screens are simple and the budget is tight, one Flutter code base covers both platforms and cuts the cost by about a third. We tell you which fits during discovery.
Banking and finance apps
Cards, transfers, loans; sign-up with SİMA, biometrics, screenshots blocked.
Loyalty and e-commerce
QR codes, bonuses, receipts, a basket, card and instalment payments.
For field staff
Drivers, couriers, service engineers: offline work, photos, GPS, signatures.
Booking a service
Free times, reminders, payment, results; for clinics and service centres.
Taking over an existing app
A code audit, fewer crashes, store ratings and crash reports watched.

Questions
When does the app appear in the stores?
Apple’s review usually takes 1 to 3 days, Google’s from a few hours to 3 days. We plan the launch date with that margin.
Whose account will the app be in?
Your company’s Apple and Google developer accounts. We help open them and only get access rights ourselves.
