User Reviews

Users praise the app for its simplicity, reliability over many years, and a strong data history that aids fertility planning and education. Its calendar view and predictable cycle predictions are valued. However, recurring issues include stability problems after updates, potential loss of years of data when upgrading devices, limited data export/sharing options (especially to Health or doctors), and a sense of infrequent updates. Overall, it’s a highly valued tool with notable risks around stability and data portability.

Pros

Simple and straightforward interface that is easy to use.
Reliable, long-term cycle tracking with accurate predictions.
Keeps a rich, multi-year history of cycles and supports restoration across devices.
Educational value for understanding the reproductive system and fertility planning.
Clear calendar view that visually tracks cycle length and fertile days.

Cons

Stability issues: app often won’t open or crashes after updates.
Significant risk of data loss when upgrading or moving to a new device.
Limited data export/sharing options (no easy export to Health app or to doctors).
Perceived infrequent updates/maintenance.

I just updated the app around 26 Dec 22 and realized that I can no longer send the graph in the original format to my email for record- there are errors in the format and it is in an unreadable format. Please rectify
