Looking for an effective self-block application for Android

My phone is a Samsung A55. Fully updated.

I have ADHD and autism, which is to say that I have a very obsessive personality. I have used various blockers over the years to prevent me from wasting time on apps and websites.

Lock me Out has helped me for many years to curb my smartphone usage. Unfortunately, it stopped working, as it became easy to circumvent by either forcing the program to stop or uninstalling it. I have been in contact with the developer, but they weren't able to find a solution and eventually stopped responding to my emails.

So I need an app that prevents me from disabling blocks at all.

While I can pay for an app even if it is a little expensive, I cannot justify an expensive subscription priced in US dollars (although I might do so if there's no other alternative).

Any suggestions that could help me out? I'm using my phone 24/7, I can't stand it anymore. And I cannot simply turn it off because I have a toddler, and I must be accessible to my wife for emergencies when she leaves the home with him.

There are also many ways to use a smartphone that are actually useful, positive, and non-addictive. And I'd rather be able to access these functionalities.

Thanks!
