Frequently Asked Questions
How does Senara wake me up?
Senara uses gentle vibrations delivered through the ring on your finger to wake you. The ring monitors your sleep stages overnight and activates the vibration alarm during your lightest sleep phase within your set wake window — so you wake up naturally, not jolted awake mid-deep-sleep.
Is it comfortable to sleep in?
Yes! Senara is designed with an ultra-thin, lightweight titanium profile that most users forget they're wearing. The hypoallergenic finish is gentle on skin and suitable for all-night wear. If for any reason you're not comfortable in the first 60 days, we offer a full money-back guarantee.
How long does the battery last?
The Senara ring lasts up to 7 days on a single charge. Charging takes under 90 minutes using the included magnetic charging dock. A low-battery notification is sent to your phone when it's time to charge.
Does it work with my phone?
Yes, Senara is compatible with both iOS (iPhone 10 and later) and Android (8.0 and above) via the free Senara app. The app lets you set your wake window, view your sleep data, and customize vibration intensity.

Technology & Materials
Titanium Construction
Senara is built from aerospace-grade titanium — lightweight, durable, and hypoallergenic. The ring is water-resistant up to 50 meters, so you can wear it swimming, showering, or working out without worry.
Vibration Wake Technology
Our patented micro-vibration motor is tuned to wake you with the gentlest effective pulse. Unlike phone alarms or sound-based devices, Senara wakes only the wearer — no disruption to your partner or household.
Sleep Science
Senara's onboard sensors track heart rate variability and movement to determine your sleep stage in real time. By waking you during light sleep rather than deep sleep, Senara helps you start the day with clarity and energy instead of grogginess.

It's Not Laziness. It's Neurology.
The teenage brain doesn't just "sleep in." It's trapped in a cycle most people — including doctors — never explain.
They Can't Fall Asleep
Their brain gets wired before bed, even without screens. Sleep doesn't come until 1-2 AM. Their alarm is 4 hours away.
They Can't Hear the Alarm
Their brain filters sound during deep sleep. Louder alarms don't help — their brain just filters harder.
They're a Genius When Asleep
Teenage brains in semi-sleep can solve puzzles, uninstall apps, and navigate rooms — all to protect sleep. That genius works against every alarm you set.
