User reviews

I love it

Omg, I’m blown away. This is the best tracker app I’ve come across in my life.
Main things like about them:
1. The very first has to be their inclusivity. They have an information panel in the app with answers to questions about stuff like STIs, sexuality, contraceptives, and so much more, alongside the resources to find further help if needed.
2. The tracking setup itself. There’s a calendar view, and a daily view with options to track your flow, how many pads/tampons/cups you’ve gone through so far in the day, your emotions, your symptoms, and more. You can also set reminders on it for appointments or important dates.
3. Your privacy is valued. You can set a pin to open the app, and you can chose to delete all tracked data if you need to.
Bonus: the artwork and style of it all is appealing to the eye, and the app is easy to navigate.

Overall, I’m a big fan!

A little glitch

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.

Super Datenschutz konforme Alternative

Ich habe mir die App runter geladen um eine Alternative zur Flo App zu haben die besser mit meinen Sensiblen Gesundheitsdaten umgeht
Und bin sehr Happy mit der App.
Es ist alles sehr übersichtlich und es lässt sich sehr einfach und viel traken. Außerdem sagt sie ziemlich genau meine Periode voraus.
Sie wurde von der Internetseite Privacy not included als sehr gut beurteilt und somit eine sehr gute Datenschutz konforme Alternative zur Flo und ähnlichen Apps.

Love this app! Please make a widget and option to link accounts/share info with others

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.

Simply the best— Bye Clue!!

This is the best app that I have ever used for my cycle tracking. It’s simple, not a whole lot of bloatware, and most importantly, PRIVATE. With Euki, Privacy is not a promise, it’s the standard from the start. NO ACCOUNT, NO SIGNUP, just plug and play.

The only two feedbacks I would give:

1. A bit more trackers, particularly if maybe the “body” section was broken up into different categories—cravings, stool, etc.
2. Allowing users to set their own “False Screen” password. I’m thinking of a hypothetical situation in which one would be forced to open the app, and they might raise an eyebrow to a “1111”.
