I use the following cause I forget lots of crap...
There is no substitute for Reptiscan... I have a few old phones that I have it downloaded on so I keep an old phone with each rack. Yaaa wifi....
I also use Final Countdown. It gives you infinite countdowns/alarms and you can place each clutch on its own counter....
I have Manything downloaded which turns your own phones into security cameras. This means you can watch a clutch pip while you are at work...
I have World of Ball Python just for that on the fly ID Database...
Weather App for shipping and receiving purposes.....
I always keep an eye out for stuff that makes life easier...
