I use reptilescan android app (and complementary web app) to track everything. Also trying pythonhead tracker atm, it has a free account you can drive test too.

I'm not really satisfied with the first (costs 20 $), the second is still missing some useful functions like who has to eat when.

As far as what record I've given up keeping defecation record after 10 snakes, everything else goes on there except daily spot cleaning.
