A fully native Kotlin app with biometric auth and instant payments.

Vesper wanted parity with the best fintech apps on Android. We built natively with Kotlin and Jetpack Compose, sharing a design language with the marketing site.

Cold start sits below 200ms thanks to baseline profiles, dependency tuning, and a deliberately lean module graph.

Biometric auth, instant payments, and a polished onboarding flow shipped in the first release.
