    New data. New perspective.

    The patterns only show up over time.

    One day is an anecdote. A week is evidence. As your history grows, TempusBack surfaces what is impossible to see a day at a time.

    The week in one screen

    Where it all went.

    Every part of your life ranked by the hours it really took and the time nobody chose pulled out and named. One tracked week and the guessing is over.

    Screen time, with consequences

    Know what your phone costs you.

    Other apps count your minutes. TempusBack shows you what those minutes interrupted: the project, the evening, the work you meant to finish. That is the number that actually changes something.

    Then it becomes a plan.

    Every week, your own patterns come back as a short list of moves, with the time each one hands you. No streaks to protect, no guilt. Just the next thing worth doing.

    Notes
    1. * Lifetime figures assume 62 remaining years and 16 waking hours a day. In the app they use your real average.
    2. ** Each estimate applies the reduction measured in the studies below to the daily phone time you choose with the slider. The studies ran for 2 to 12 weeks and a meta-analysis found these effects fade over time [5], so the curves assume each tool’s effect halves every year; that is why they level off. Some studies measured only the apps people chose to cut down, so savings on your total phone time may be lower. TempusBack’s estimate pools the two studies of tools that, like TempusBack, show people their own usage, work with their personal goals and don’t block apps: 21% [1] and 38% [6], weighted by number of participants ≈ 31%. Both studies were small (58 people in total) and short, and [6] also used in-the-moment reminders; this is not a study of TempusBack itself. App limits cut time on the limited apps by 16%, but about half of it moved to other apps [4].
