Noticed the recent threads about herp tracking apps out there. Not really one to toot my own horn much, but figured I'd jump in. I wrote a herp tracking database app called ScerpDB. It's pretty simple to use and includes scheduling functions, activity reports, growth charts, as well as sales and expense tracking. There's also a genetic (progeny) calculator tool that you can use to help plan out pairings, if you're a breeder. The display can be setup to match your rack setups, with virtual cage cards to represent locations within the racks. Not that you need to have racks, you can do it however you want. It's 100% free to use and always will be (unless someone decides to make me a buyout offer to good to pass up... very unlikely, lol).
I do need to work on documentation, so it's kind of learn it as you go, but really not that hard to figure out. Anyway, just putting it out there for anyone wanting to check out all their options, or not thrilled with their current record-keeping.
