Hi can anyone tell me which one is more reliable? So I sleep with a Trackle every night and wake up every morning at 5:40 just to use Daysy. After Daysy beeps, I take the Trackle out and go back to sleep. Later in the morning I sync each device to its respective app to see and log the day's temperature. It's always much higher on Trackle than on Daysy and I've read more than once that vaginal temps are the most reliable. However, I also see that Daysy has a 99.4% accuracy rate so which one is accurate? Now I'm absolutely sure that I ovulated on Sunday and today's number on the trackle looks promising. But with daysy I'm not sure how to interpret it. It is still significantly higher than Sunday and the preceeding days but lower than I would like? Yesterday the trackle had some kind of glitch so while it was syncing it refused to log but Daysy's number was nice and high so I was happy today's number is still about the coverline but significantly lower than yesterday's. What should I make of this?
