I think this app deserves better than a lot of these reviews. I use it regularly when Im showing homes. As a Realtor, its very impressive for me to send my client our Shared Route for the day via email. As for limitations on the amount of destinations, ten works very well for me, but I could see some people might need more. I also love it on the iPad! I live in Toronto and have not had any problem adding addresses to the app.
