i use an app that helps me keep track of everything: feeding day reminders, struck or refused and prey type, shedding and days since last shed, weight tracking, time since last full enclosure cleaning, and any other things i like to keep track of.

i only have 3 snakes, but i really like having the app. when i got a new phone, i was able to download all my data and re-upload it into my new phone. you can also download the info into a spread sheet and print it out.
