An honest, no bull app

Unlike so many others I've tried, this app does what it says, no more, no less. Allows me to choose what info I want displayed, not what the developer 'thinks' I need. Also gives me an estimated time until the charge is complete, which most others do not. Bottom line is, this app does everything I need a battery monitor to do, in as elegant manor as one could want. A 'job well done' to the developer!

In addition, unlike Jestmaster, I have not had an issue with the Standby estimate being off so dramatically, and my main display is incremental in single digits. This is either a bug in his/her app or perhaps they need to update the app? My old iPad Air is probably what the app was designed around!



what does the u.s. iTunes app store have against system optimizer apps, system memory refreshing apps, & battery boosting apps?
every time i find one that does it all, inevitably the app store phases it out.
these types of utilities are readily available in every other store, but not in the u.s. store.
it's as though apple doesn't want it's customers to be able to enjoy the benefits of this type of utility, and they don't have the right to decide that for their customers.
(and yet they have done just that)
hasn't anyone out there noticed this?
i cannot be the only person.


Standby bug

This app works OK and seems to be fairly accurate (in increments of 5 only, not precise); however STANDBY is never right. If audio listening is 40 hours for example, how could standby be 15 hours? Other apps show 150 or 200 hours. This is a bug requiring attention to make this program properly usable.
