The only person they're cheating is themselves. Any systems designed to help you curb phone addictions only work if you do the legwork and are in the mindset of wanting to improve. The systems are only guardrails to lean on when you're tired. If you decide to vault the rails, that's not sustainable in any way.
You’re cheating yourself in that case. Or to put it another way, if you really don’t want to comply you can just delete the app.
Yeah, just echoing what people have replied but I did try put some safeguards in such as screens - if it detects a screen it won't unblock your apps
