Porn blocking

I use Truple Web Filter (a VPN), Blocker X and Incoquito (to switch completely off the incognito mode on Chrome).
Every App mentioned above is completely free (except for Incoquito); you can find them on the Play Store (don't know if they're avaible on the App Store).
However, pay attenction: VPNs and porn blockers don't represent the solution to your problem. In fact there are no porn blockers and VPNs which works at 100%: some sites, a few image aggregators will always slip out and be accessible (I can assure you this, because I've been able to watch porn with all the turned-on apps that I mentioned before).

The best way to stop watch porn is creating new habits, keeping your head busy with tasks and, obviously, using all will-power you have.

If you can't stop watching compulsively porn, you should ask for help to a psychotherapist.

 

You'll never find something which blocks every porn content posted on Internet. Trust me, before the three apps I advised to you I tried many others (even the fee-based ones) and no one, I repeat, no one could stop me from porn at 100%.
However, I could suggest you to use Appblock to lock apps and settings with a password (ask someone to set it up for you); maybe it can help

 

I am a big and grateful fan of blockers. In my experience, they are at their best as a recovery tool when coupled with the perspective @A. Skywalker shares here. I sometimes fall into the trap of believing all will be well because my blocker is on. This never ends well. Never.

So very well put and thanks for the reminder.

 

I use spin browser and app lock

 

I currently use EverAccountable which is an accountability program that I pay per year. It doesn't actually block porn, but it sends accountability reports/screenshots of what I am seeing to accountability partners that I have assigned (either through text alerts or emails). What's great about this program is that it's the shame that prevents me from relapsing or looking up P instead of blockers. It also sends emails out if I deactivate or uninstall the program.

I'm not really into using hard-blockers, since you can always find a way around them, but I do have some hard blocks on a few of my devices.
