Data Master - Monitor Cellular & Wifi Data Usage App Reviews

Did not get past setup. Tried to contact support; couldnt. Very frustrated right now and I feel swindled. iOS 10 users beware!

It really gets the job done, I cant stop using it!

I used to be able to adjust the cell usage if the app lost track. But now it wont update the usage when I enter the new usage amt and hit either Save or Done. Please fix.

It took me 1 minute to set up and it easily keeps me informed.

This app can be useful (although I found its count is different from my providers). I dont like user interface at all - looks like amateur homepage from the 1990s.

Have only been using for a day, but it provides exactly the detail I need. Love having an app rather than clicking through Settings to find Cell Usage AND having to remember to Reset Stats at each billing cycle. That was annoying; this is simple and provides even more information.

The app is hard to use an I dont believe it shows accurate data. Hard to find total of data used. If the iPhone is restarted it removed all the data tracking so if it is restated you dont know where your at in a month. Hard to keep track.

If you have a pay as go phone this is a must have. I would give this 5 stars if I could verify the accuracy.

I like the idea of this app but it does not keep correct track of your usage. Im constantly adjusting the value of my cellular usage.

Use this one everyday.. Great app

Great idea, but every time I start the app (once daily), it resets itself and I have to reinstall it every time its used. This needs to get fixed... Badly. Reinstalling it every time you want to use it is unacceptable.

This application is very user friendly. It provides upto 99% correct data usage information. I will highly recommend this app.

First impressions: - works great - whats with the looks? Cheap.

Setup counter does not allow me to put my numbers in without it turning off and going back to the main page

Very accurate. I reset this app right at midnight when my new cellular month began, and it was within 10 megs accurate. Update for 2.0: Some things have been moved around in the settings and moved to other areas. Very confusing at first of youve been used to the older versions. Still seems pretty accurate.

Crashes when I try to display usage history

Ive used all the data usage apps and this apps works the best.

Apple should have this built into iOS. Essential app.

The cellular data usage reported in the app is more than the data actually used (as shown from the network company)

Works great. Keeps track of the data usage and helps prevent us from going over.
