Works great
Just upgraded to the Pro version bc I wanted to be able to use the alarms. Its great, very simple to use but not lacking in its ability. I like that it uses the BTT data to calculate ovulation. Seems to work...Im not pregnant yet. (which is what Im going for...)
Im only giving it four stars because even in the proversion it interrupts you with a push notification to come rate them. Thats annoying.
