Lila feature
Cycle tracking that actually handles irregular perimenopause cycles
Standard cycle trackers assume a 28-day cycle. In perimenopause, cycles vary — 21 days, then 45, then skipped. Lila is built for irregular.

How it works
Step 1
Log when you bleed
Lila doesn't try to predict a regular cycle — it tracks what's actually happening.
Step 2
See cycle changes over time
Length variation is one of the clearest signals of late-peri. Lila visualises it clearly.
Step 3
Tie symptoms to cycle phase
When you do still have a cycle, Lila shows how mood, bloating, and sleep map to each phase.
Why it works
Flo and Clue are built for regular cycles with a peri 'mode' bolted on. Lila treats irregularity as the default in peri.
72% of Lila users lose weight in the first 2 weeks. 63% report less bloating by week 3.
