I love Glow!

For those of us who dont have the time for temp charting, this app is pretty accurate at estimating your fertility period and even more accurate if you were to get a positive opk. It is very important to log symptoms, opks, etc. If you dont log, how can you expect to get good estimation/accurate results? You put into the app what you get out! As soon as I logged my two positive opks, my fertility period readjusted on Glow and I ovulated a week before I thought I wouldve if I hadnt logged my results and symptoms.
