This app does 6 simple things which you can do on your iPhone with 6 different apps-but all in one place. I have an age calculator and a tally counter and a timer but it's nice to have one app open to have all those things at your fingertips. The BEST part is the percentage correct calculator; believe it or not this is the only one I've found which simply gives a percentage correct as you log responses. It would be awesome if you could save this data-maybe as an update?
