Ruby Rhythm vs BreathZen

Say goodbye to overly complicated and pink period tracking and hello to Ruby Rhythm, the app that goes beyond the calendar. Ruby Rhythm integrates the wisdom of Traditional Chinese Medicine (TCM) to help you understand your cycle like never before. Track your periods and get insights into your body's unique rhythm. Ruby Rhythm isn’t just about dates; it’s about phases. With our easy-to-use interface, you can see if you're in your Inner Winter, Inner Spring, Inner Summer or Inner Autumn Phase, and see how they affect your energy, mood, and well-being. Ruby Rhythm is designed to empower you with knowledge, support, and cute animals to make every day of your cycle a little more fun. Your data never leaves your device and is never used or shared for advertising, data collection, or marketing purposes.

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.
