### 1/5 — Fake app doesn’t do anything

*2017-09-30, version 2.0.2*

Links to websites and adverts, I’m surprised this is on the App Store. It’s nothing but rubbish, just a collection of links and pop up ads. Waste of time. The English is terrible.

### 1/5 — It just shows ads

*2017-09-28*

Could not see anything about my battery.  Just add and requests for money.

### 1/5 — Click bait!!!  Full of spam

*2017-07-31*

Don't even try this app. It's crap. All ad.

### 1/5 — Whaaat?

*2017-03-20*

This junk has absolutely nothing to do with charging at all. It's all spam crap. DONT WASTE YOUR TIME.

### 1/5 — Not even a battery app

*2016-09-23*

All this app does is pops up ads no functionality what-so-ever. At least not on an iPhone 7

This is dum (do not try out)

### 1/5 — You are stupid!

*2019-04-25*

Now how do I report this dude…

### 1/5 — Why was this created

*2019-02-24*

To many ads literally all it said was “wait till 1~2% to check”and then goes blank

### 1/5 — Faulty

*2018-07-07, version 2.0.2*

Doesn’t do what it says it will do.  Non functional app.  Perhaps scam or malware.  I can’t say this certainly, but i had bad feeling about after .. difficultly uninstall.

### 1/5 — Does not work

*2017-11-29, version 2.0.2*

Soon after plugging you’re device in it starts working telling you 1hour and 17 minutes then the time increases exponentially.

### 1/5 — Time

*2017-10-27, version 2.0.2*

I was at 99 percent and it told me I had 2 hours left which I found out shortly that it was lying

### 4/5 — Batt 100%.

*2018-09-25, version 2.0.2*

Does everything it says it does, but the free version doesn’t work but the paid one works fine, then u can delete free version. If u r looking for an alarm wen phone is fully charged, then this is PERFECT!

### 2/5 — A review

*2017-04-05, version 2.0*

Application is riddled with google ads and I can't see the charge voltage or amps which was as described? Or not intuitive enough to get to.

### 2/5 — Won't let you start

*2017-02-20, version 2.0*

In order to access this app, once downloaded, it directs yo to Instagram page. Not sure if it is looking for you to give it a review first (without trying it?) or wanting you to make a hashtag. Guess what?... not everyone has instagram, or is remotely interested. I gave it 2 stars, as a a good idea. Long way to go for 5 guys. Deleted.
