Use a session boundary instead of an all-day promise
A rule like use Instagram less is difficult to act on because it has no moment attached to it. A fifteen- or thirty-minute session timer creates a clear point where you can reconsider.
The first limit does not need to be aggressive. Pick one that reveals when intentional use usually turns into automatic use, then adjust it from experience.
Keep Instagram alone or group it with the rest of the loop
If Instagram is the main problem, give it its own timer. If your usual pattern is Instagram followed by another feed, you can place those apps together under one shared countdown.
Come To also supports multiple timer profiles, so a video app can have a different limit from your social-feed timer.
The timer does not read your Instagram content
Come To needs Android-level app activity information to know whether a selected app is active. Its optional app-switching service is designed around package changes, not reading posts, messages or screen content.
The reminder is about elapsed selected-app use, not what you viewed.
