Ratings and reviews

Seems like a solid app but the subscription is a no go for me. Paying monthly to use a utility that should be a one-time purchase is insulting, especially when my Google drive is acting as a cloud host. Give me the option to make a one-time $8-$10 payment and I'm a happy man. I understand revenue drives development, but this is a new app in a young space. You'll make up for it in volume.

Simple notification issues... Need all devices to notify when any device drops to 30->20% ("plan to charge soon"). Need all devices to notify when charged to 80->100% ("ready if needed"). Different sounds would not work. Didn't work with all connected and remote devices. Issues upgrading devices... can't remove old devices, app confused between old/new, graphs freeze for hours, even after uninstalling all devices & starting fresh. After wasting a month, didn't bother checking energy rates.

Great app. wished it had a one time purchase option. subscription ? no way. not for that functionality . what's bothering me is that the app icon is constantly showing on the watch, unless i disable monitoring completely
