- ✓Real-time alerts to phone and base station for abnormal readings
- ✓Comfortable wearable sock fits babies ages 0–18 months

- ✓Uses SafeSense radar technology to detect breathing from across the room

Angelcare AC337
Under-mattress movement sensor with video and two-way audio
Angelcare has been a trusted name in infant breathing monitoring since the 1990s. The AC337 combines an under-mattress movement sensor with a full video monitor — reassurance without attaching anything to your baby. At $130, it offers meaningful peace of mind at a fraction of the Owlet's cost, though it detects motion rather than oxygen levels.
PROS
- ✓Under-mattress sensor pad detects breathing movement without touching baby
- ✓Sounds alarm if no movement detected for 20 seconds
- ✓Full video monitor with night vision and two-way audio included
CONS
- ✕Movement sensor only — does not track heart rate or SpO2

Snuza Hero MD
Clip-on abdominal breathing monitor with no base station needed

PROS
- ✓Clips to diaper — works in any crib, bassinet, or travel bed
- ✓Vibrates gently at 15-second pause; audible alarm at 20 seconds
- ✓No WiFi, no app required — fully self-contained
CONS
