In development. No launch date announced yet.
Most cycle apps record. Lambi explains — and it is built for two people from the ground up, not with a partner view added on afterwards.
Logging for years does not automatically mean understanding what your body is doing. Lambi explains what it is showing you — what a phase is, why a prediction moved, what a pattern might mean — so the app leaves you knowing more than when you started.
Your partner is not a read-only guest bolted on at the end. They get their own experience with guidance on how to actually show up for you — and they never see your raw entries. What reaches them is computed on our servers from the permissions you set, so 'they only see what I chose' is enforced in code, not promised in a policy.
A textbook 28-day cycle does not describe everyone. Lambi sizes its prediction window from your own history and shows you the confidence behind it, instead of inventing a precise date. When a prediction is wrong, you can say so, and it learns.
This is health data about your body. We built the app so that we cannot read the sensitive parts, and neither can anyone else.
One email when Lambi is available. Nothing else, and you can leave at any time.
