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

I wish there was a way to add more categories of things related to the hormone cycles that I frequently track, such as back pain and sense of smell. But other than that I have no complaints!

I love the app’s privacy and information availability on it. However I feel as if it’s missing some symptoms people may experience, such as back pain, and leg cramps, ect. I also wish it sent a notification a week before and a few days before warning me of my period like other apps do. I did submit a suggestion for that on their site but I hadn’t mentioned the back pain one so I decided to make a review.

Would love the app even more if it were possible to also track the type of pad size/absorbtion being used. A pad with wings is not nor is it the same as an overnight maxi pad with wings, and for me I know that distinction matters. Cause if I need to use x3+ long ultra thin pads with wings one day and x3+ maxi pad overnight wings the next day, and all I can click is “heavy flow” that’s a bit unhelpful, as those are two very different types of heavy flow days. Would it be possible to be able to log pad type/absorbency? Like after you click it, then get to click which type just like how they have all options on the box with a picture of which product you’re purchasing? And I’m sure tampon users would also appreciate this feature. That’s all! And also thank you for fixing the cycle glitch, it’s awesome now at predicting again! ________________ Past Review: Please for the love of moon cycles everywhere, please fix this bug. Could you please fix the glitch that doesn’t recalculate cycle length? The cycle tracker is way off. And even though the last four cycles have begun at the same interval of time, it’s still off by a week due to a fluke cycle that began early. And every cycle before the fluke also began at the same interval of time as the cycles after the fluke. I thought that after a few cycles it would recalculate to accurately reflect what the new data is showing, but it hasn’t and I don’t think it ever will. I really like this app, but the fact that it’s an entire week off makes it unusable for me. If I can’t track my cycle accurately, then why would I continue to use this app? Please for the love of moon cycles everywhere, please fix this bug. I don’t want to have to find yet another app after fleeing from clue. Thank you!
