MaskAlarm: CPAP Mask-Off Alarm

MaskAlarm watches your CPAP mask all night and sounds a loud alarm the moment it detects the mask has come off — so you can put it back on and keep your therapy on track.

Prop your phone at the bedside, tap Start, and MaskAlarm uses your camera and AI to check whether your mask is on. If it slips off during the night, a customizable alarm wakes you to fix it.

KEY FEATURES
• Camera-based mask-off detection — no wearables or extra hardware
• Loud, customizable wake-up alarm with gentle ramp-up options
• Optional detached-hose alerts (on + Hose plans) — best-effort extra alerts for when the mask stays on but the hose is unclipped
• Caregiver alerts — notify a loved one when the alarm sounds, by text (US numbers) or through the MaskAlarm app on their phone
• Leaving the bed disarms the alarm automatically; it re-arms when you're back with your mask on
• Nightly AI sleep reports, session history and trends
• A monthly calendar view to help you stay consistent
• Share your progress or send a usage report to your clinician
• A first-night checklist that walks you through setup step by step
• Works with your existing CPAP setup

CAREGIVER ALERTS
Looking after someone else's therapy? MaskAlarm can alert a caregiver when the mask-off alarm keeps sounding — by text message (US phone numbers) or through the app on a second phone. Each caregiver chooses how quickly their own phone is alerted, gets a quiet all-clear when the alarm resolves, and can see a list of every alert received. Turn each caregiver on or off, choose whether the alarm also sounds on the sleeper's phone (silence it for someone in the room, keep it on for a caregiver farther away), and send a test alert anytime to make sure it's working.

FOR CARE ORGANIZATIONS
Facilities can license MaskAlarm by the seat and activate each phone with a simple code — no account or card on the phone. Learn more at cpapmaskalarm.com/for-organizations.
