Oh and the ovulation feature as just being a symptom to mark down isn’t the best it has symptoms of its own and some girls don’t know when theirs is ### 5/5 — Gender Inclusive *2026-07-17, version 1.9.5* Not only does this app not once use gendered language to talk about things like menstruation in the info section, they actively go out of their way to include genderqueer people in the conversation, as a trans person, i never wanted to use period trackers because they either stole my data, or used language that made my dysphoria skyrocket. they even went so far as to warn people when sites they linked in the app used gendered language. incredible app, wonderful inclusivity ### 1/5 — Completely useless *2026-07-09, version 1.9.5* Literally the majority of the reason women log their periods, to track ovulation, is not even an option. For women trying to get pregnant or even to avoid pregnancy, this app is totally worthless. ### 5/5 — I like it. Just one bug I noticed *2026-06-29, version 1.9.5* I was recommended this app when it came out that the more popular apps were causing privacy concerns. I tried many but this one was the best. There is this bug that happens sometimes, where the "include in cycle summary" box randomly unchecks itself when I'm adding in data for a day. It's not a big deal, but I did want to bring it to attention. ### 5/5 — Best period tracker so far *2026-06-25, version 1.9.5* I’ve used a lot of period trackers and so far this is my favourite. No adds, no pushing for subscriptions all the time, just a period tracker that values privacy. ### 4/5 — Basic *2026-06-16, version 1.9.5* Basic period tracker. Would like to see back pain as a symptom and the ability to track ovulation. ### 4/5 — Simple app *2026-06-15, version 1.9.5* Easy to use. Would be great if HRT could be added as a category, especially for cyclic medication. ### 3/5 — It’s okay *2026-06-11, version 1.9.5* Pretty barebones. Wish I could change the skin tone on the icons. ### 1/5 — Sales data and can’t even track very well. *2026-06-11, version 1.9.5* Pls download any other app ### 4/5 — great app! *2026-06-05, version 1.9.5* i love this app!! private, free and a great and accurate tracker!! i would just love a wider range of symptoms and emotions, such as back aches (which are one of my worst symptoms), and also the opportunity to opt in to reminder notifications for when your period is on the way! ## Frequently asked questions about Euki ### What does Euki do?
