About Feelmo

We don't guess your feelings. We watch over your regulation.

Feelmo is a wellbeing app for iPhone and Apple Watch that translates the small fluctuations of your heartbeat — read by Apple Watch — into six gentle characters.

What this app holds dear

• We observe, never guess. — We watch over your body's regulation, not infer your emotions
• The ordinary counts. — Days that are neither good nor bad have value of their own
• Your data is yours. — Records stay on your device. Never sold, never tracked

Who makes it

Feelmo is crafted in Japan by Lumo, a research-led health-science studio. Its core heart-rate-variability (HRV) analysis was born from joint research with Keio University.

The app is raised in Higashi-Mikawa, Aichi — a step away from the speed of the metropolis, where everyday life keeps its own quiet rhythm.

What it does

• Measures the Regulation Score and watches over your days with the six companions
• Emotion Log (calendar, graph, analysis)
• Four guided breathing sessions, by state
• Behavior log and AI coaching

What it does not do

Feelmo is not a medical device and is not intended for diagnosis or treatment. For any health concern, please consult a medical professional.
