nice game. however, I purchased the "ad-free" option some time ago (about half a year) and this is simply ignored by more recent updates of the program. contacting the developer is like talking to a grave - no answer.

app works perfect, however due to tbe limited apple font/app concept, not all apps support the new fonts.

nice and useful frontend. however, line limits are not very helpful, when issueing more complex calculations. therefore, of very limited use for real math, but nice to play around with math at school level.

my son likes it very much.
