What is Reddit's opinion of Mobiwol: NoRoot Firewall?

From 3.5 billion Reddit comments

Download this

https://play.google.com/store/apps/details?id=com.netspark.firewall

And u can restrict data to ANY app u want

Or download this

https://play.google.com/store/apps/details?id=app.greyshirts.firewall

And u can restrict urls as well

You could use a VPN app for that. Lot's of them need root to work, but there are a few that don't. Last time I cared about this, Mobiwol did the work flawlessly.

Edit: added a link.

mobiwol firewall. with this, you can prevent certain apps from using background data over mobile (or prevent them from using mobile data completely). my data usage has plummeted.

And if you want to restrict foreground usage too then try Mobiwol

Could be a wallpaper app maybe?
I would suggest remove data & wifi access for suspecting apps one at a time and see if it helps. I guess you would be able to this in settings otherwise you could look at Mobiwal.

Maybe something (that uses a lot of bandwith) is running in the background?

Most easy way (and to avoind crap like this) is to simply turn data on when you need it and off when you don't. Or just leave it on and use an firewall app and grant only access to internet to (for example) viber. I have used mobiwol in the past, can recommend it. https://play.google.com/store/apps/details?id=com.netspark.firewall&hl=en

I use Curbi to block apps and Mobiwol to block apps being able to connect to the internet.

Mobiwol works well especially if you have an Android phone as you can't remove or deactivate the built in Google search feature but you can firewall block it.

Curbi is not free but not expensive. It can block apps and categories, you can also set up usable times and usage quotas.

I'd suggest this: https://play.google.com/store/apps/details?id=com.netspark.firewall&hl=en

Great data reporting and you can also use it to control data usage if you have an app using more than you would like.

Wow, what a bunch of mean responses to a valid question.

I'd suggest this one: https://play.google.com/store/apps/details?id=com.netspark.firewall&hl=en

You can control per app access to cell data or all data, turn off background data, and it has good data usage reporting.

This can probably do the trick for ya: https://play.google.com/store/apps/details?id=com.netspark.firewall&hl=en

Setup rules for what you want blocked and then turn the firewall on/off as needed.

I don't think you can do this with the stock Android and no additional app. I understand you only want certain apps to use mobile Internet. The most traffic is most likely done by apps like Facebook, Twitter and when you want to update apps. You can try https://play.google.com/store/apps/details?id=com.netspark.firewall, I didn't use it since I do heavy traffic only on WiFi (I have 1.5 GB mobile Internet). One way to limit the usage (also battery usage) is to stay on 3G , not on 4G/LTE (if possible). Again, only updating apps and apps that haev to load and display images (Facebook, Twitter, Instagram and so on) could make a lot of traffic. You may also use NFC tags, programmed to automatically turn on WiFi and to turn off mobile Internet).

This will do the trick: https://play.google.com/store/apps/details?id=com.netspark.firewall&hl=en

This guy will do the same thing and is a dedicated firewall app if you don't need the data compression stuff in Opera: https://play.google.com/store/apps/details?id=com.netspark.firewall&hl=en

There is an app called Mobiwol that doesn't require root and allows you to turn on/off network access on a per-app basis.

This firewall will let you block cell data for apps while allowing wifi data, among other handy features: https://play.google.com/store/apps/details?id=com.netspark.firewall&hl=en

You might find Mobiwol firewall useful, good data reporting and you can individually restrict apps' access to cell data: https://play.google.com/store/apps/details?id=com.netspark.firewall&hl=en

Mobiwol: https://play.google.com/store/apps/details?id=com.netspark.firewall&hl=en

All local, no VPN, does all that you ask for ;)

Mobiwol firewall is the closest to RW's data control: https://play.google.com/store/apps/details?id=com.netspark.firewall&hl=en

Use a different launcher if you want to be rid of the Google search bar on the home screen.

Games I would recommend Badland: https://play.google.com/store/apps/details?id=com.frogmind.badland&hl=en

You can use an app like Mobiwol in the link below for similar controls to the 2.0 RW app.
