About Feelmo: Stress, Sleep & HRV
Understand your daily pattern with Apple Watch sleep and HRV records. Review sleep debt, log your mood and try guided breathing. Feelmo compares your morning with your own usual range. A Balance Score requires compatible records; mood logging and breathing can be used separately.
▼ Three simple steps
1. Wear your Apple Watch to bed
2. Open Feelmo in the morning
3. Check your score and one of six companions, then consider how to approach the day
A score requires valid sleep and heart-rate records in Apple Health. If compatible data is insufficient, Feelmo does not invent one.
▼ What is Balance Score?
It is Feelmo’s own 0–100 reference based on HRV—the small timing changes between heartbeats. Feelmo generally learns your usual pattern over about two weeks, then compares this morning with your personal range. Timing varies with wear time and available data.
It does not measure health, sleep quality, or the autonomic nervous system itself. Higher or lower is not simply “good” or “bad”; it is a prompt to check in with yourself.
▼ Cycle tracking
Log period dates, flow, symptoms and basal body temperature, and review them in Calendar and Trends. See an estimate of when your next period may start.
▼ Free features
• Balance Score on days with valid records
• Measurement-based “Body Pattern,” kept separate from the “State of Mind” you choose to log
• Period and cycle tracking
• Six guided breathing modes with full-screen character animation
• Today’s and yesterday’s sleep, daylight, steps, hydration, and more
• Weather and air-pressure changes
• Apple Watch app and widgets

Tomorrow’s Outlook uses trends in your past records; it does not guarantee accuracy or a future condition. Habit and pressure patterns show associations, not cause and effect.
