Period date

Tarikh period yang dipaparkan adalah tepat…tq Blood…sebab senang saya nak plan apa2 aktiviti sekiranya saya bersedia bila saya akan period…

Idk bro

AWESOME APP!!! But I really wish that we can have more options and accessories for our character :3

Great app!

This is probably the best app that I’ve used. It’s extremely accurate and I can share it with my husband so he knows when I’m gonna be more emotional. Highly recommend if you’re looking for an app to remind you of your start date.

LOVE

Ive tried so many different period tracking apps and couple apps but this is BYFAR the best one! Its very accurate and so helpful for my husband to keep track of my cycles and he is now very educated on all things period! Definitely recommend!! They even have a section where you can purchase products from their brand! 😁

Love it but one suggestion

I would love if this app connects and is integrated with the apple health app as well as I would wish that there could be more symptoms listed because as women our menstrual cycle comes with a-lot to handle not to mention those who have endocrine system issues like PCOS or endometriosis.
