This is a free app and Im judging it on being free. Useful, convenient and plenty of variables; temp, mucus, sensation, medications, procedures, secondary symptoms, notes, etc. I like that it is compatible with TCYOFs fertility rules and can be set to show fertile days in another color. A little counter intuitive with dry days being in the period settings and sticky mucus triggering fertile days. Can be worked around though.
What really bugs me is the ovulation and period predictor. I can see if it predicted a period on the current cycle using peak +14 but this thing is predicting ovulation and periods based on the past cycles just like the Calendar Days/Rhythm Method. As a seasoned charter, this bugs the snot out of me! I have peak and period notes all over my current and future months and theyre wrong. You cant have two true peaks in a cycle and LPs do not run 20 days. Need to fix that algorithm.
I like that it pulls FAM/NFP into the electronic age but honestly will not be giving up my paper charts for this. Maybe I will like the paid version better but is it worth the $3.99? Eh, well see.
