  9. [R34] Calculator for iPad₊ 1/5 · US Was good until the Royal Flush ads started to crash it: I used this app for years with a small ad in the corner, then regular updates started encroaching screen space and today some gambling game called Royal Flush just took over the entire screen making this app useless.

  18. [R60] Calculator for iPad₊ 1/5 · US ADS?! Really?!?: This is the exact same iPhone app, yet for some reason you insist that ads are necessary on the iPad version. Why? To continue milking us money, of course!
