Priced like an app that teaches a whole language
Outrageously over priced and there is no lifetime purchase. Sorry, but NO WAY. Does not accept keyboard input like the ENTER key to advance to the next one, so horribly uncomfortable to use - I can't lift my hand to touch the screen hundreds and hundreds of times per session. Unfortunately that it lack Vietnamese or Khmer, those were what I was looking for. At this price point, I might as well google "random number list" and punch them into google translate and drill myself. Y'all are off your rockers with this pricing.
