The distinction between sleep and nap times don’t make sense to me, and makes entry of some sleep patterns ambiguous.

Last night I slept for a few hours, woke for a few hours, and then slept for a few more hours. Both sleep periods were similarly long and during the night, so it feels arbitrary to have to enter one as sleep and the other as a nap.

There are other days where I get little sleep during the night, but have a longer period of sleep during the day. Which one should I consider “sleep” and which one is a “nap”?

The distinction between sleep and naps seems arbitrary and the app does not provide clear definitions which distinguish between the two. It seems odd to force special treatment of one sleep time over all others. I’d rather be able to enter an arbitrary number of sleeps, and perhaps optionally tag a sleep period as a “nap” or similar for those who might care about the distinction.
