Worked great until now

This is the best BBT thermometer I’ve owned. It worked great until last week. I have to constantly unpair and pair it. Now when I try to record an OPK the app crashes. Yes, I’ve changed the battery, tried to fix any Bluetooth issues, etc. I think it may need a new update.

This has been great for me! It syncs with my phone via Bluetooth, which is great on mornings where I can hardly stay awake. I’ve used it for 6 months and have only once had my temperature not register. I did have to replace the battery already, which surprised me but makes sense because it’s being used every day. I wish the app would let me set a reminder to log info each day because sometimes I forgot to log additional information, but I do take my BBT each day.

Missing a valuable component

I love the app and really have no complaints. I just wish a time stamp would be added to the opk pictures so when I compare cycles, I know at which time of the day I got what result. For this reason, I have to use the glow app as well and honesty use that one more often.
