I love that I can create and adapt sets to focus on whatever my child is weak in, with pretty much any conceivable variation. I feel the only drawback is the lack of logging. It does offer a record of your best time on each set, but if you even change one variable, that record resets.

I love this app very much. It helps with time management in my (small) class where the children need to speed up with sums. It does, however, have too long a pause between sums that gets added to overall time with the sums. If that could get shortened in some way by a green or red flash instead of the arrow that the child needs to register before it goes on, that would be great. Nevertheless, well done.

Crashes! Seemed to be working fine for my daughter, then I configured some things and now it freezes up a few problems into the drill and has to be shut down. Also, why do it set it to do 25 problems and when it starts it says there's 169?
