"The 7 day always comes up with a server error. The 16 day only works half the time and I get the server error the rest of the time."
"I think they don't have the necessary server capacity to handle the subscribers. If you like error messages and constantly reloading screens which is super annoying when looking at several locations in trip planning you'll love this."

Design and usability issues driving negative reviews.
Users cannot evaluate the app without creating an account and providing payment information, leading to immediate uninstalls and distrust
"I agree with Mark1850 -- simply state the price for the advanced version instead of playing games by requiring our information first."
GPS and location services fail to work properly, showing users hundreds of miles from actual position
"The arrow that should provide weather in your current location generally has me 200 miles away from where I am"
App advertises different trial periods in different places, causing unexpected charges
"The free trial period is only seven days when you sign up by the app. When you download this app you will get an email that will tell you that it is 15 days. This is not true."
Users get stuck in screens and cannot navigate back without force-closing the app
"Save your money - this app is absolutely horrible. When you open the forecast, you can't close the screen without having to end the app and relaunch. Seriously bad."
