Always improving

This app is exactly what I want. New features are added and feedback is taken very seriously. Bugs get fixed (unlike Grindr). I wouldn’t go with any other.

Always Broken

Ah yes, another day that ends in “Y” and this app just…doesn’t work. Remove it and the re-add all the info back…and then two days later it just random breaks and you have to delete it and start over.

The best sexual heath tracking app for gay men

Love this app. If the date filtering in the analytics section worked correctly. It would be 4 1/2 to maybe five stars.
