Tarsoul AB

Quiet apps, made carefully.

We make small, focused iOS apps that respect your time and your privacy.

VitaSine

Our first app — a reflective biorhythm journal. Track your physical, emotional and intellectual cycles, log how each day went, and watch a personal pattern emerge. No tracking, no servers, no accounts. Everything stays on your device.
