## What is BioRhythm MiMo?

Transform the way you start and end each day with MiMo.
Build a healthier daily rhythm through data with the MiMo app.
1. Melatonin Secretion Curve
   See how your body’s melatonin levels change throughout the day with an easy-to-read curve. Check when secretion begins and ends, how stable your secretion pattern has been over the past week, and how today’s level compares with the recommended range.
2. Circadian Rhythm Score
   Understand your complex circadian rhythm with a simple score from 0 to 100. Track the timing, stability, secretion level, and efficiency of your daily rhythm.
3. Your Personal Chronotype
   Discover which of eight chronotypes best matches you and explore your social jet lag—the difference between your weekday and weekend sleep schedules.
4. Weekly Comparison View
   Overlay today’s rhythm with the previous six days in a single view to see how consistently your rhythm is maintained.
5. Rhythm Log
   Track your sleep stages—including deep, REM, and light sleep—along with heart rate, step count, and active energy. Review your trends by day, week, month, or year.
[Wearable Device Guidelines]
For more accurate circadian rhythm analysis, please follow these wearable device guidelines.
1. Wear Your Device for at Least 13 Hours a Day
   If your wear time is too short, melatonin analysis may not be available for that day.
2. Avoid Removing It for 7 Consecutive Hours or More
   Brief periods without your device, such as while showering, are fine. Leaving it behind for an extended period may affect your analysis.
3. Wear It While You Sleep
   Not wearing your device during sleep may affect the analysis for both that day and the previous day.
4. Wear It Consistently Every Day
   A stability score requires at least four days of valid data within the most recent seven days. Consistent use provides more accurate and comprehensive results.
[Important Information]
• This app analyzes health data recorded in Apple HealthKit to provide information about your circadian rhythm. For accurate analysis, you must wear a compatible device and grant access to the required health data.
• This app is a lifestyle utility designed to support everyday well-being. It is not intended for medical diagnosis or treatment, nor is it intended to treat or improve sleep disorders.

## Version history (last 5 releases)

### 1.3.1 — 2026-10-27

• Bedtime guidance now uses your average sleep onset over the past two weeks.
• Retake the survey from Settings — your previous answers are filled in to edit.
• Survey time entry switched to a 24-hour clock.
• Tidied App info and Guide screens, added a video guide.
• Fixed health data collection stopping while the app was closed.

### 1.3.0 — 2026-10-22

• The melatonin graph now runs from noon to noon
A whole night fits in one view, and last night's curve is ready from 8 AM.

• Tonight's forecast
See when melatonin is expected to start tonight, before the night begins.

• Sleep record analysis
Sleep that was recorded in several pieces across one night is now analyzed together, so the whole night is reflected more accurately. Naps are counted separately.

• Overall score grades
Simplified from ten levels to five, so your current state is easier to read.

• Jump back to today
Tap the tab you're already on to return to today's date.

With the new analysis window, past records are recalculated. On days that don't meet it, you'll see an explanation instead of the curve.

We’ve improved sleep tracking and analysis.
• Split sleep sessions are now combined into a single night for more accurate total sleep time.
