Time-stamped logs beat checkmarks for timing goals

For a goal like sleep schedule, time-of-day logging is the only way to actually track consistency. If you only log completion, you’re counting whether you did the thing, not whether you did it at the right time. That’s useless when the whole point is timing.

The problem with checkmarks is they collapse hours of difference into a binary “done/not done.” Going to bed at 9 PM and 1 AM both get a check. That’s not data. You need to see drift, patterns, and whether you’re actually shifting the window.

So when comparing methods, ask: can the app record a timestamp easily? Some habit trackers let you set a time window and then log completion with a single tap—those don’t actually capture when you did it. You want something that either forces you to enter a time or auto-timestamp. Even a simple note app where you write “bedtime: 10:45” works fine.

If you’re comparing a fancy tracker that only shows a streak vs. a paper log where you jot down the time, the paper log wins for this goal. The tracker with timestamps and a chart of your actual bedtimes wins over both.

Don’t overthink it. You just need a record of the clock, not a gold star.
