Spo2 Monitoring Throughout the Day：Pebble Aspire has a built-in spo2 detection system that monitors your blood oxygen saturation 24/7. If it falls too low the band will vibrate, so you can take time to breathe and regain your balance.(Note:This product is not a medical device, and is not intended to diagnose, treat, cure or prevent any disease. )
All Day Heart Rate Monitoring: Pebble Aspire's heart rate monitoring technology uses an optical lens and data-based data processing to accurately monitor your heart rate 24 hours a day. Be instantly alerted when your heart rate drops below or rises above safe levels.
1.57’’ FullView Screen: Pebble Aspire has a 1.57-inch HD fullview screen, the size of the display area is 1.48 times larger, and a low-frame 64% screen-to-body ratio. Combine that with the high-resolution 240x360 display at 282 ppi and you have something really impressive to look at on your wrist.
2 Week Battery Life: The endurance athlete in the wearables world, Pebble Aspire offers an incredible battery life of 14 days for typical use, and 10 days for heavy ones.
