Thank you so much, Caryn! 🌸 We're really glad Selin is keeping up with your cycle — being just 2 days off is something we're always working to improve even further. It means a lot to know you feel your data is safe with us. We hope you continue to love using Selin! 💛

This is literally the BEST period tracker I've ever seen. I'm normally very picky on these, but this is what I've always wanted. There's no age limit as long as you're 10 or older, barely any ads, and so many blogs that are pretty useful. Thank you devs for making my dreams come true!

This is a really great app! There is no age limit, so don't worry about it not letting u use under 16. BEST PART: If you have a question about something, there is an ai that will answer any of ur questions so that u don't have to have those acward talked with ur parents/gaurdain(s). There's also vods on things like how to shave personal parts of ur body, does and don't of tampons, etc. Overall, this is a really great app, and I totally recommend!
