About Jera

Jera is a gentle alarm clock app for iPhone: your alarm starts almost silent and rises over a few minutes, reaching full volume at the time you set. It’s made by IX Labs Ltd, a small company in London.

Why we’re building it

Most alarms go from silence to full volume in one beat. We wanted mornings to start more gently, without the worry of oversleeping: a sound that rolls in, reaches full volume exactly when you asked, and has backups for the days that matter.

We also wanted to be straight about what an alarm can do. Phones can’t reliably tell which stage of sleep you’re in, so Jera doesn’t pretend to, and no alarm can switch off the grogginess right after waking. What an alarm can do is make the start of the day calmer and a steady wake time easier to keep. Our blog goes through the research behind these choices, with every source linked.

What we stand by

No account: Your alarms and settings stay on your devices and sync through your own iCloud. We can’t see them.
No sleep-stage guessing: Jera wakes you at the time you choose, not at a moment it thinks you’re sleeping lightly.
Wellness, not medicine: Jera is designed to support a gentler wake-up. It isn’t a medical device; if you regularly struggle to wake up or feel unrested, talk to a doctor.
Sources you can check: Every research finding on our blog links to the peer-reviewed paper it comes from.
