Good morning.
The free LOOKEE® App. Your whole night, one tap away.
The free LOOKEE® App turns a night of readings into something you can actually read. Reminders you set, every moment of the night, and reports you can share with your doctor.

For iPhone and Android. No subscription. Works with every LOOKEE® sleep monitor, the A320B oximeter and the CardioScope™ ECG monitor.


Customized reminders
Reminders that work your way
You decide what the ring watches for and how it tells you. Turn a reminder on for the ring, for your phone, or both.
- Reminder on the device: the ring vibrates on your finger
- App notification: your phone shows an alert too
- Low oxygen threshold you choose, for example 90%
- Pulse rate limits, low and high, for example 50 and 100 bpm
- Vibration intensity, finger-out and connection-loss reminders

Your morning summary
Two numbers that sum up the night
Your O2 Score puts the whole night on a scale of ten. Your ODI counts how many times an hour your oxygen dropped, at both the 3% and the 4% level. Below them, the time you spent in each oxygen range, and space for your own notes.
- O2 Score out of 10
- ODI at 3% and 4%, with drop counts
- Oxygen and pulse distribution through the night

Professional reports
The file you hand to your doctor
- Time spent in each oxygen band
- ODI 3% and 4%: number of drops, time in drops, average length
- Your own thresholds, and the full oxygen, pulse and movement traces
- Export as PDF, CSV or image
The ODI 3% and ODI 4% values are informational metrics derived from overnight oxygen data collected by your LOOKEE® device. They are intended for general wellness and sleep-trend tracking only. These results are not medical diagnoses and should not be used to identify or treat any health condition. If you have concerns about your breathing or sleep, please consult a qualified healthcare professional.
