Perla

About

A period tracker that keeps all your data private. It requires no account, uses no cloud storage, and shows no advertisements. Every function operates directly on your device. Perla was created when our wives grew tired of trackers that sell personal information or inundate users with ads. We therefore eliminated the server completely. All features, including the prediction engine, AI insights powered by Apple Intelligence, and fertility scoring, process locally. Wrist temperature from Apple Watch eliminates the need for costly thermometers. It accommodates users with PCOS, endometriosis, or pregnancy, and supports eight birth control methods. Available for $19.99 annually or a $49.99 one-time lifetime purchase.
