Why are some of the heart rate bars missing?

Note: gaps in Cardiogram data are normal and and do not indicate any health issues on their own. Cardiogram reads data from your wearable, so when data doesn’t show up and there’s a gap in the data, it’s either because no data was collected by the wearable’s sensor (i.e. not having proper contact with the skin), or the manufacturer’s algorithm determined that the beats-per-minute reading may be inaccurate.

This can happen during workouts or sleep, since the watch can move and lose direct contact with skin (e.g. due to sweat or tossing & turning). To help prevent this, make sure the watch is in contact with your skin (e.g. tighten the band before a workout or bedtime).

Cardiogram does not limit the number of data points collected per day. To make Cardiogram collect data more frequently, check out this article!
