### 3/5 — Battery Meter

*2021-03-04*

Displays basic capacity information.
Edit: Needs updating for latest version of iOS.

### 5/5 — Great app

*2019-06-26, version 1.0*

### 5/5 — Perfect

*2019-01-01*

wonder full works ipad 1st genaration

### 2/5 — iOS 11 problems

*2017-11-07*

Great app, but won’t work on iOS 11. Can you please update the app

### 5/5 — ari-yo

*2016-06-21, version 1.0*

what does the u.s. iTunes app store have against system optimizer apps, system memory refreshing apps, & battery boosting apps? 
seriously! 
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.

### 5/5 — An honest, no bull app

*2016-03-23, version 1.0*

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!

### 5/5 — Ok

*2015-09-27, version 1.0*

Ok

### 3/5 — Standby reply

*2015-08-18, version 1.0*

I think they mean when you have it on the charger

### 5/5 — Excellent

*2014-11-07*

Great app. Works like a charm, and does exactly what it says on the box. Worth the effort.

### 4/5 — Good at what it needs to do

*2014-09-01, version 1.0*

Better than the built-in meter and easy to read...
