I've been building Limit, it's an Android app & website blocker that (really!) cannot be bypassed.

I'd attempted a bunch of blocking in the past, but kept finding trivial ways to disable the blocking. In the end I built Limit as a blocker I couldn't just disable.

It has pre-configured block lists for:

- Social media (algorithmic feeds) - Adult content - Gambling

Recently we added a 'hands off' mode for parents of ~teens - you can set up the device once, let Limit block social media, but without invading their privacy.
