Using w/o Apple Watch

Though I’m almost certain that this absolutely works at its finest if you do indeed have an Apple Watch, I’m not one to wear watches. Just seems pointless and irritable on wrist. Opinions aside, I am in love with the app just as it sits on my iPhone and iPad and can see how much time left I have to use on each device. I don’t quite see the point of getting the premium seeing as to the extra feature(s) are minuscule, but again, with no Apple Watch, my stance on it is slightly different. It’s a nifty app, regardless, and I’m glad I found it as I was waiting in line to get inside Walgreens. Ugh! ‘Rona virus problems!

I’ve purchased the premium version to get notifications on Watch when my iPhone battery its fully charged (100%). Unfortunately it doesn’t work (I even left the phone on charging extra 45minutes ) I’m using iPhone 6s iOS 11.2.5 series 1 s1P processor watchOS 4.2.2

Lovely app and works 99%of the time. Sometimes it's says on the Watch that I have 92% battery on my iphone and when I checked the phone it's showing 94 %battery level. If you can add customs notifications on the Watch and vice versa (set at 93% to notify when reach that percentage will be awesome) Overall it's a very good app. Congratulations!

Found this app several weeks ago and have used it several times to check on my IPad. Great app and I will continue using it as it’s what I wanted to acquire months ago.
