Ava Fertility Tracker

Anyone try the Ava <a href="https://play.google.com/store/apps/details?id=com.glow.android">Fertility tracker</a> bracelet?!? Any options? Good or bad? Please no harsh judgment. I am on 3 month TTC. I have read a lot on the website for Ava Women. But wanted other opinions.

TIA
