Replaced My Go-To

Sleepcraft provides the equivalent info, and more useful info, than the app I’d been using for a while. I pop it open every morning to see if I’m improving at all, and I am. Having measurable data is useful.

Good, but…

It keeps double-counting both my sleep hours and steps. Huge thanks for keeping it free!!

Response from developer

Hi DrBeePhD, thanks for reporting this. Could you please send screenshots and details to support@sleepcraft.app? That would help me investigate the double-counting issue and fix it. Thanks!

Great visualization!

Excellent perspective on your sleep dynamics.
