The first period tracker that actually gets irregular cycles.
See what Miru can do
“Every tracker assumes a 28-day cycle.
Mine has never been 28 days.”
How it works
Quick 30-second check-in. Mood, symptoms, period status. That's all Miru needs.
AI recognizes YOUR unique patterns — not a textbook average. It gets smarter every day.
Know what's coming before you feel it — symptoms, mood shifts, your next period.
Every morning, Miru tells you what to expect — energy levels, mood shifts, symptoms — all based on YOUR logged patterns. Like checking the weather, but for your body.
Good morning,
Sarah
Cycle day 12 — energy is rising! Your cramps usually show up in about 10 days, so enjoy this window.
