I recently traveled out of state and Mapkin provided excellent instructions on my drives. I especially liked how it had current area updates in some places (not all, but thats a user contribution thing). The app gives you repeated instructions with rapid changes (i.e. Stay in the left lane to and fork to the left at 435 West; or reduced speed ahead because of roadwork). It also checks in with you during long lapses of silence (i.e. I needed to 26 miles to my exit and Mapkin says "hello, Im just checking in, you have 8 miles to go until your exit on 23rd street").
The more users pride info regarding roadwork, etc. the better the app will be.
The one area for improvement had to do when we were looking for a Target store that wed visited the day before. For some reason it didnt show that store in the list that populated when I searched for Target stores nearest to my location. It turned out the app left out Super Target store locations because I didnt specify "Super Target." Not a deal breaker, just good to note when searching for a place. Also it would be so nice if, when listing Starbucks locations, the app would state "Starbucks inside Marriott hotel" versus a standalone. But again I thinks thats something can be remedied over time with users input.
I had a young adult with me and she noted how impressed she was with Mapkin....so much so that she downloaded it onto her phone which has precious little space left, if that counts for anything.
