KidCheck

KidCheck is honestly very very cheap! For only $25 you get even free updates AND free support even on Sundays. The interface looks very simple - not too fancy, it has the exact level of detail needed to be easy for the eye and great to navigate. Moreover of course you can track attendance with just a few clicks which proves it to be immensely capable solution.

There's not much to say when trying to find something bad about using it - there's almost nothing to say! One thing I do find a little strange is that it doesn't function on Mac with Firefox or IE8 but that's really no problem (Firefox doesn't function all that well there anyways). It works for both Windows and Mac though and as it is web-based it really shouldn't cause you any trouble - use Chrome though!

For such a low price and easy way to manage check-ins while it is all secure and you can share notifications quickly, I find this tool to be one of the finest of the field. If you value quality, easily reachable customer service and low price, then this is the one to choose!
