Energy Clock

About Energy Clock

Energy Clock is a private app for iPhone and Android for tracking sleep and planning the day around your energy — for anyone 13 and up, with or without a watch.

What it's for

Most sleep apps answer questions nobody asked, with stage graphs and scores that are hard to act on. Energy Clock tries to answer four simple ones every day: how much did I sleep, how much sleep debt do I have, when will my energy likely be highest and lowest today, and when should I start winding down tonight.

It works without a watch, and it fits teens, adults and older adults alike: the same sleep engine for everyone, with starting guidance and wording that fit your age and the shape of your days — school, work, shifts, family or your own schedule.

What it's built on

  • Plain language. Sleep debt reads “No sleep debt” or “48 min”. Confidence is described in words, never a made-up percentage.
  • Honest about estimates. The energy curve is a simplified illustration of well-known ideas about sleep and alertness, labeled as an estimate. The app doesn't show sleep stages it can't really know.
  • No shaming. The streak rewards consistency, not hours slept, and a missed night just starts a new count.
  • Your data stays yours. No account, no server, no ads and no analytics in the app. Everything is on your phone.
  • You stay in charge. Your targets are plain numbers you can change. The app may suggest adjusting one, and explains why, but never changes it on its own.
