Why calls work
Answering a call and speaking takes more of your brain than tapping Stop. That small effort is often enough to carry you past the urge to roll over.
What to look for
A wake-up call should ring at your time, talk to you, check you are really up (steps, not just a tap), and call again if you fall back asleep.
How Life OS does it
Set your wake time and your ELO calls you. It checks for real movement from your iPhone and Apple Watch, and if you go back to sleep it rings again.
Questions people ask
Is there an app that calls you to wake you up?
Yes. Life OS's ELO can call you at your wake time and call again until you are up.
Why do I sleep through my alarm?
Usually short sleep, an alarm that lands in deep sleep, or one that is too easy to silence. See our guide on alarms for heavy sleepers.
