Overall it's worth it – Logic Puzzles Review

This app has a nice interface and many of the previous problems with puzzles have been fixed. However, there are occassional puzzles where assumptions need to be made (like Alex being a male name), ambiguous wording (John is not Mr. Smith, who is the one that came in 4th), certain information may need to be looked up (GM makes Buicks), and occasional misspellings (poinson instead of poison, preformed instead of performed). It does at least keep track of which puzzles have been completed. It's nice to see that they are continually working to improve it.
