I used Fertility Friend for several years (pre-TTC and while TTC). There is a place to put in spotting prior to your period starting. It also allows you to record light, medium, and heavy flow.
The Ava app left a lot to be desired, for me. It was not accurate in calculating my O day (always two days later than it actually was). You don't get to record much or play with anything. Fertility Friend was MUCH more interactive and always accurate because of all the other data I could input. I used the Ava bracelet for temps and put them into FF.
