Comments on Once -A special period tracker for Android

★★★★☆ Em · May 12, 2026

Please make a list view e.g. January 01/01/2026. Symptom - backache 01/01/2026. Symptom - food cravings 02/01/2026. Symptom - cramps 02/01/2026. Period starts - flow heavy 04/01/2026. Symptom - severe cramps 06/01/2026. Symptom - backache 06/01/2026. Period finishes February 03/02/2026. Etc... just a list view allows you to see patterns of symptoms more easily, and you can screenshot the list all in one go rather than having to click on each individual day one by one.

★★★★★ Nikki Evelyn Overton · Jul 9, 2024

Love it!! I've been using this app for years now. It's normally always right on track with my period predictions. And it's really simple to use. I would recommend it to anyone.

★★★★★ Amy Soaki · May 3, 2024

I do love using this app to track my period. I think it would be a helpful option to add if you're pregnant, and to be able to add when you ovulated (based on blood test or LH) to make it more accurate. Thank you.

It was a decent app until they try to force me to agree to their terms and services (WHICH ISN'T IS IN ENGLISH BTW.) And I can't use the app until I agree to the terms and services, but I can't read the terms and services cuz it's not in English. So I guess I have to delete this app now.

★★☆☆☆ Jennifer Walker · Mar 27, 2021

Used this app for years but the pop-up ads have gotten out of control. I don't even know how to close them because they're in Chinese. Super annoying and not worth it anymore. Bye, Once.
