I’ve been using this app for more than 5 years, it has a lot of functions, gives you a lot of information and always reminds you about your upcoming “events”
Easy to use and practical!
Sasnuhy
I like this app because it’s extremely easy to use and accountable. It makes sure you track everything and provides a detailed explanation for your flow, ovulation period and warns you if something may be off. I’d rate it 10 stars if I could.
Simply the best
