Bonzen

AI-native meditation app on iOS that adapts each session to how users actually feel in the moment.

  • iOS
  • Swift
  • AI/ML
  • Product Design

Problem

Most mindfulness apps feel static: same content, same tone, and weak response to user context.

Solution

Designed a lightweight check-in + adaptive session engine so users get the right intervention for their current state.

Impact

Shipped on the App Store with a repeatable daily-use loop focused on relevance, trust, and retention learning.

Bonzen is the clearest expression of how I build AI consumer products: tight loops, emotionally relevant UX, and measurable post-launch learning. Visit bonzen.app or the App Store listing. Read the companion essay: Philosophy of Bonzen.

Product loop

  1. Check in quickly
  2. Get a guided reset or coaching response
  3. Reflect with a short prompt
  4. Receive a next-step suggestion

Product principles

  • Relevance over novelty: match help to current state
  • Simplicity under stress: low-friction interactions first
  • Behavior over hype: instrument what users repeat

Why it matters

Bonzen demonstrates that useful AI products are less about one perfect generation and more about a repeatable user loop that keeps delivering value.
