I am just getting it set up and it seems to track everything you could possibly want to ever know about any of your animals. In addition as Maxrr said it is completely free.
Only downside I see is that when you are first setting it up you have to enter alot of information because it does not have the specific information about all reptile species entered in ahead of time.
Keep in mind that while this is time consuming at first it is incredibly helpfull later as you only need to do it once for any specific type of reptile you keep.
Also you do not have to enter information into all fields, most are optional, but I had to look up the exact taxonomy of my snakes to enter their species into the program lol.
Basically it takes a little bit of time the first time you run it but you are left with what looks like a grand daddy top of the line luxury product after that.
At least worth checking out.
