Worked just fine for me

I used this gps app during an 8 day trip where i traveled from san jose to manuel antonio, monte verde, la fortuna and back to san jose. It got me everywhere i needed to go with no problems. You dont need to use any data with this app as it downloads all maps to the phone. It may not be the best gps, but for the traveller on a budget, you cant beat the price.
