Very bad app. Very bad support

Very bad app. Very bad support.

1st this app was nice and helpful. With the time the app got bad and worse.

Slow execution of search. Hanging a lot in the menues.
Seems as if some words are not properly stored in the offline modus or at least these words are not found.
Further the app grow up and up and its taking a lot of space - 1GB - right now.
Since the last updates there is no way to restore the app on a new or other device except contacting their very very bad app support.
To restore the app they want you to send them sensitive data like mac address, wifi address, billing history, etc.

I strongly recommend NOT to buy this app, dont do in app purchase!!
Pay attention. Seems they just want your money.
