Much too expensive...... Veel te duur
I thought I could use this to help teach English. It looks promising but after the free trial you have to pay, and pay you do! It really is a shame that you have to pay so much. If they ever decide to sell the app as a normal, one time only payment, then I would probably consider buying it because it is an interesting app. Re-think your payment plan and you might end up selling a lot more. Until then I would not recommend installing it.
