BreathZen vs Lune Cycle Tracker

Close your eyes. You can still follow every breath. BreathZen is a breathing rhythm app designed for quiet practice. Gentle human breath guidance makes inhale and exhale distinct by ear, while holds remain silent. There are no spoken commands and no need to keep watching the screen. FIVE BUILT-IN PATTERNS — FREE • 4-7-8 Breath: a longer exhale for winding down • Box Breathing: four equal phases for a steady rhythm • Coherent Breathing: smooth 5.5-second inhales and exhales • 4-6 Calm Breath: gentle pacing without holds • Morning Wake Breath: an inhale-led rhythm for starting the day MADE FOR CLOSED EYES AND LOCKED SCREENS With sound enabled, your practice continues when the screen locks or you switch apps. The Lock Screen and Control Center show the current phase, pattern, overall progress, and playback state, with pause and resume controls close at hand. A RHYTHM THAT FITS YOU Set inhale, hold, exhale, and rest in half-second steps, up to 60 seconds per phase. Preview the animation and sound while you edit, with live cycle length, breaths per minute, and session duration. Editing and auditioning are free. Saving custom patterns is a one-time purchase, never a subscription. COUNT BREATHS OR SET A TIME Practice by rounds or choose 1–120 minutes. When time is up, BreathZen finishes the last complete breath instead of cutting you off halfway through a phase. Paused time does not count against the session. PRIVATE BY DESIGN No account, ads, tracking, or analytics SDK. Everyday practice works offline. Optionally save completed sessions to Apple Health as mindful minutes. All five built-in patterns and the complete core practice experience remain free. Custom pattern saving is a one-time unlock. Practice only within a comfortable range. Stop and return to natural breathing if you feel dizzy, strained, or unwell. BreathZen supports general wellness and mindfulness; it does not provide medical diagnosis or treatment.

Lune is a simple, private period tracker designed to help you understand your cycle without compromising your health data. Log your period dates and Lune automatically predicts your next period, fertile window, and ovulation day. The more cycles you log, the more accurate the predictions become. Features: • Track your menstrual cycle and predict future periods • See your fertile window and estimated ovulation day • Understand your cycle phase (menstrual, follicular, ovulation, luteal) • Gentle reminders 2 days before your next expected period • Beautiful, easy-to-read week strip showing where you are in your cycle Your privacy is the priority: Lune stores all data locally on your device only. No account required. No data is ever uploaded to a server, shared with third parties, sold, or used for advertising — ever. Uninstalling the app permanently deletes everything. Lune is not a medical device and does not provide medical advice. Cycle predictions are estimates based on your logged history.
