Projects

  • 12levels

    A native iOS app for learning English vocabulary by reading — books matched to a 12-step CEFR ladder, FSRS spaced repetition, and notifications timed to the forgetting curve.

  • Ommo

    A native iOS breathing app — Core Haptics lead the rhythm so a session works eyes-closed, with a generative visual and a procedural soundscape. Offline-first, no accounts.
