When you updated your app? I will give you 5 stars.

Absolutely wonderful in keeping my Nexus 7 tab apps in line. Thanks.

Ish. J. May 22, 2016     

Love the app!

Before, it would keep telling me about hogs that I stopped (would be nice if it did that automatically) and tell me that they are still hogs. Now it tells me the hogs are the same as unused apps? Really? Pretty screwy.

I've updated to the latest build and the remaining time on the battery icon on top of my toolbar is still missing on my OnePlus two. Please fix!

Quite handy and useful app

Mea. W. Apr 21, 2016     

One of the most useful apps out there!! My phone used to die in the middle of the day and I never knew why until I used this app! It's very useful!

I tried loading new update and get no action. The update page just stays there looking at me telling me there is an update available. I tried rebooting, complete shut down and restart . . . still nothing.

Jer. L. Mar 27, 2016     

Why does the the latest update require my phone ID information? eStar shouldn't need that level of private information to optimize usage.

For example, the NBC News app is rated 4.5 stars, yet it consumes 5.4 watts of power on my Nexus 6. That's more power than any other popular news app and results in very poor battery life. It also consumes significantly more CPU than other news apps. App Tune-up Kit is a much better indicator of excessive battery consumption.

Nice app - if it would stay running.

Ric. Q. Sep 19, 2015     

No longer gives app battery usage. I use to check battery status but it became broken after last update. Hope it's fixed soon

Zac. F. Sep 15, 2015     

It keeps force closing on me please fix

Effective in analysing. If you only have 512MB RAM, then UNINSTALL this after testing, it uses 22MB RAM and stays active, resulting in other things being more frequently displaced from RAM and restarting. On unrooted devices, unless there is a manufacturer original startup manager, you cannot prevent an app from starting, only autokill and hope it doesn't restart itself. Do not forget this and leave it, as it will hurt performance on low RAM devices.

Cas. F. May 30, 2015     

The app used to work pretty well, but the most recent update seems useless. It is much slower, the UI is less intuitive, and it doen't seem to do anything; it seems to just play roulette with random apps, whether they are actually running or not. When I refresh, it picks totally different apps, as well as the ones that I "stopped". When I stop them, if the option is even available, nothing changes. Also, sometimes the same apps will show up twice... the time to be gained also seems to be random.

Dav. R. May 28, 2015     

What a great way to find battery friendly alternatives to your powermongering apps. Crashes when I do specific searches.

Dil. J. May 31, 2015     

It just stops working sometimes after the recent update. Please fix it. Otherwise, great app.

Dmi. L. Jun 26, 2015     

Useful to give you ideas of actual power hogs on your phone. A bit disappointing that some of the apps I need are such hogs. Maybe just maybe we can use this to tell the app makers they need to up their code.

Nig. P. May 23, 2015     

Works really well and very informative on battery drain, but from a few updates ago the icon in notification bar showing estimated time remaining does not change until the app is opened.

Ada. B. Jun 8, 2015     

Works fine for me. I don't know why people are being so critical about it. It does what it's supposed to do.

Son. M. Jun 25, 2015     

Loved this app but it no longer works. No longer shows in the notification bar and the app no longer does anything. Fix please

Hasn't worked on my Note Edge since I got the Lollipop update. Always FC once I try to optimize. Worked great before though.
