It all sounds great except for one major problem... the database won't download. If you read the comments on GooglePlay about the program, this is a common problem across the board. I haven't been able to download the off-line database for over 3 months now. Needing internet connection for my tablet, not having this information readily downloadable makes this program useless to wi-fi only tablets. Looks like if someone is going to write an article about an app, they would do more research beforehand.
