Some people wrap their phone in an elastic band or there’s always Opal if you want more fine grained control: https://apps.apple.com/gb/app/opal-screen-time-control/id149...
I liked Opal, but with Intenty I tried to create an alternative way without blockers or limits. For some reason, app blockers and time limits are very frustrating for me and rarely work. That was one of the primary motivations for the app creation. While I admit that for the majority setting proper limits on certain apps will work.
