Kloe is a period and mood tracking brand creating a private, research-informed app for iPhone and Android. Designed to keep users in control of their personal information, the app requires no account and stores entries on the phone rather than in the cloud. Users can log periods, moods, symptoms and notes, view cycle predictions and charts, and explore research-backed symptom cards that explain what may be happening and suggest possible actions.

Kloe also supports tracking symptoms associated with endometriosis and adapts predictions for conditions and life stages including PCOS, PMDD and perimenopause. Personalisation features include themes, app icons and home screen widgets. The app offers cycle-based breast self-check reminders and lets users create PDF reports for clinicians or cycle cards for partners; nothing is shared unless the user chooses to send it.

Kloe offers a free plan, a monthly or yearly subscription, and a lifetime purchase option. The service is planned for iPhone and Android and supports English, Spanish, Portuguese, German, French and Ukrainian
