User Reviews

Users consistently praise Euki for strong privacy and ease of use, with many noting no heavy premium gating and solid educational content. However, multiple reviews highlight critical drawbacks: cycle prediction accuracy issues and recalculation bugs; data portability problems when moving devices; limited symptom tracking options (desire for more categories and details); UI aesthetics and missing dark mode; and occasional stability glitches. Privacy and usability are strong, but reliability and feature completeness around cycle tracking and data portability need attention.

Pros

Privacy-first design with strong data protection and openness about data use
Easy-to-use, straightforward logging and a simple interface
No aggressive premium gating; many features are free
Helpful information/education about reproductive health
Positive cycle prediction reliability reported by several users

Cons

Inaccurate cycle predictions and cycle-length recalculation bugs
Data porting issues when moving to a new device; years of data can be lost
Missing or limited symptom categories and tracking details (back pain, pad type, discharge, etc.)
UI aesthetics and accessibility concerns; lack of dark mode
Stability issues and occasional broken functionality

Recent reviews

Overall the app is nice and simple, but there is a weird glitch where when you look at the calendar not all the days show or they get a little scrambled? It is hard to understand the projections or past info because of this.

I really like this app, and heard it doesn’t sell your data/is secure- love that! I do wish there was a widget available to see where I’m at in my cycle each day. It can impact health issues so it’s helpful to be reminded where I’m at daily with an easy visual reminder on my phone. I also wish there was an option to link accounts with a partner, can be another helpful tool for people whose cycle impacts their health status significantly.
