Bloom is a simple log for your intimate life. Record sessions, notice patterns, and—if you’d like—try a Bluetooth heart-rate device to capture how your body responds.
Keep the moments you want to remember, in as much—or as little—detail as feels right. Every session becomes part of a private history you can return to whenever you’re curious.
Send your partner a private note after a shared session. They can write back and reveal yours right from the link—no Bloom account needed.

Bloom holds the details you choose to record, then offers patterns back gently. No score. No single answer. Just another way to understand what has been true for you.
When a Bluetooth heart-rate device connects, Bloom can hold the trace alongside the rest of the session.
Compare the details you record with where you are in your cycle, then decide what feels meaningful to you.
Ratings, vibes, timing, and context can reveal small threads you might not remember on their own.
Bloom is for those who are a little curious about themselves. Not tracking toward a goal. Just paying attention.
Some things are worth noticing. Times of the month that feel different. Sessions that stand out. Small shifts you might never remember without something to hold them.
Try the Bluetooth watch or heart-rate sensor you already have. If it shares a live signal, Bloom can capture it through the session and keep it with your private record.

Bloom turns changes in your live heart-rate signal into color and movement. As the signal rises and settles, the petals respond with it.
Watch it for yourself—or let someone beside you watch it unfold.

The longer you tend this, the more it can give back. Bloom keeps your charts and session history ready whenever you feel like looking.
