Most brain-training apps give you the same drills whether you slept 4 hours or 9. Lumen+ reads your sleep, HRV, and mood from Apple Health and turns it into "Brain Weather" — a daily readiness score that decides whether today is a Push Day or a Recovery Day.
36 drills, a real GPT-4o-mini AI coach that knows your actual training history, HRV-based breathing sessions, and a new no-pressure Zen Mode. Native iOS with Watch, widgets, and transparent StoreKit billing — no subscription traps.
