Signos Accountability Features

Glucose spike notifications 

Signos sends you alerts whenever your glucose spikes out of your optimal range. Use that extra energy to go on a post-meal walk, do some jumping jacks, or bang out some squats and push-ups. Or, maybe stress is fueling the spike. Bring your glucose back down with deep breathing, meditation, tai chi, or gentle yoga.

Glucose spiking is normal, and our bodies have a great regulatory system to handle it. But constantly elevated blood glucose is not healthy. Lots of damage may already be done to the body by the time people reach a pre-diabetic or diabetic range of glucose dysregulation.
