Watch Ultra

Sometimes when I track with phone and watch, journal crashes and doesn’t record night, I wish phone app automatically triggered iWatch to start and vice versa, having to start both makes them crash.

I wish instead of the swipe up to stop recording that it was a press/hold, so many times I accidentally cancel when I swipe to go to another app l.

Also wish you could record naps or continue an interrupted night specially with a newborn/toddler or red eye, when nights are perfect allow us to track as such

Money grabbing

I decided to redownload the app after a few years, only to find you now cannot even use the app without agreeing to the free trial first. They’re relying on people completely forgetting that they have signed up for the trial and then paying for the subscription. The “cancel anytime, we will send a reminder” is complete rubbish and it’s still preying on people.

Free Trial-Not, got charged

Downloaded the app, and was told it would send you an email after 5 days to warn you to discontinue the app before the end of the 7 day trial! Never sent a warning email, then was charged $76.76. Have written a number of times, but no one responds. No Refund; and really frustrated! Don’t try it, don’t purchase it!
