Go-to GPS for Truck Driver

This is my go-to app. It’s accurate 99% most of the time. Rarely, it’ll have me get off a highway exit only to get back in the highway, but this has happened to me with all the GPS’s I’ve tried. They’ve also updates how & how many truck stops/diesel stations show on the map. All this isn’t bad for a free app that I can use on my iPhone and tablet. I also really like the variety of route options given to a destination.

1) I wish this would alert me to weigh stations (opened/closed) on my route.

90 days in and Mostly good but ...

Easy to use good app good features but can’t trust it to keep you on a good route more than once so if you get a good one save it immediately.

Get rid of carpool lane recommendations because ...never in a truck.

Please look into making it possible to adjust the recommended routes by dragging your route line. (used to be able to do on Mapquest) this would be more helpful than any other upgrade.

Most times a good route but rarely will it give you a great route. When it does you’ll close the app to take care of something before you go, then and open it, input the same destination and bam you’re route is completely changed. Now the shortest route option is 30-70miles longer than the previous route provided and we added some fun skills challenges at the end like a u-turn on a 2 lane rd. or some sight seeing through a small town before we run you back onto the same hwy you just got off of and have you take the next exit.

Good luck trying to adjust your trip after the recommendation is given. this app is stubborn.

It’s like oh you liked that route did you well how about we don’t go that way again. ever.

Please add the hwy exit numbers to the standard rd name description during the route instead of waiting until you get too close to the exit to take your eyes off traffic.

Please make the roadway tags a little larger they stay way too small and don’t enlarge no matter how much you zoom in.

Good app will keep using.

A sad death of a great app.

I haul exclusively OS/OW, and this app is perfect… when it works. Let’s review based on it working, and hopefully it will work again. You can save routes and easily alter the routes as your permit changes. The unlimited stops and ability to save your route makes multi day trips a breeze. Just take the time to build your route and you know you are good. If your iPad updates or needs to restart, just reload your saved route. Some of my longer trips have 20 or more route points and this app handled them easily. When works, it is a 5 star app.

Right now it does not work at all. It actually crashes so hard I need to do a soft reset to get my iPad to function. This is particularly frustrating, as my ELD is through my iPad as well. I have tried to use it in portrait and landscape mode. With and without extra stops (no added points renders it useless to me). And I have uninstalled and reinstalled it multiple times. All to no avail. I hope it works again some day, but I can not continue to try to test an app that crashes my whole system.
