Not nearly as great as suggested

-Menu is counterintuitive and difficult to operate; needs a good redesign of its entire interface to make it simpler to use
-Drains battery very fast; not good for more than 6-8 hours of use; youll need back up battery for your phone if you use it longer
- on some occasions it produces some amazingly strange results that dont agree well with overall results (e.g. tends to cut total time thereby increasing average speed)
-It can be spotty; it misses some valuable data points and replaces them with ones that dont really correspond to overall/actual data
-Map downloads can quickly use up available memory so be careful when you download too much data
+When it works, it works great
+Its cheap (granted its not a true GPS like Garmin but its only $2.99 so it saves you a lot of money)
+ Its a very good navigation app that can be very useful. Ive used it for international travel and it works great.
+ Its benefits outweigh the drawbacks so its a great value for any mobile phone user.
If it were only better designed and simplified itd be much much better.
