Bariatric surgery prep

Your surgery date depends on CPAP compliance. Keep it.

Bariatric programs routinely require weeks of consistent CPAP use before approving surgery. MaskAlarm wakes you the moment your mask slips off — so the hours you sleep actually count — and keeps a clear nightly record of your mask-on time.

An alarm that protects your hoursThe #1 compliance killer is the mask coming off at 2am and the night not counting. MaskAlarm sounds until it's back on.
✓
A nightly usage recordEvery night's mask-on time, mask-off events, and streaks — reviewable and shareable from the app.
✓
Works with any machine and maskCamera-based. No brand lock-in, nothing extra to wear, no SD cards.
✓
Private by designCamera images are analyzed only to detect your mask; MaskAlarm never stores them and never uses them for ads.
✓
Two phones, twice the coveragePair a spare phone on the other side of the bed — they watch together, share every detection, and one subscription covers both.
Bring it alongside your machine's report

Most surgery programs primarily check your CPAP machine's own usage data. MaskAlarm is the tool that makes that data look good — by keeping the mask on — plus an independent nightly record you can show your coordinator. Ask your program what documentation they accept.
