Below please find one version of a way to keep track of your successful practice days during the 100-Day Practice Challenge.

After a few weeks of practicing at least 15 minutes daily and not skipping, you start to feel strong and virtuous; after a few months of this, you feel downright excellent.  I recommend it highly to those who haven't tried it.  And the vast boost it gives to one's cello playing to miss no days at all cannot begin to be quantified!   This may be a difficult assignment, but it is well worth the struggle.  Good luck to all, and looking forward to cello-brating with you on the other end of the 100 Days.
