EDIT: Unfortunately, I can't give this app five stars anymore. I'm not sure what happened, but for a few months now the cloud forecast has been pretty inaccurate. For example: tonight was supposed to be 0% clouds for several hours. Yet, here I am at 10:30pm - when the app still says 0% clouds - and I have 70-80% cloud cover. It's unreliable, making it challenging to schedule imaging sessions, and clear skies are at a premium. Still love the other features, though.

is it possible to add an address/location search function? it would be faster and easier than going to another map app to locate the exact location and then trying to scroll/zoom to it on your map in order to save it as a favorite. i love all the other functions and tracking. haven't tested accuracy yet, but very excited about this.

Yes! A map search feature is on the way.

From my experience, cloud cover forecasts are generally correct but are occasionally off by a few hours. In those instances, app will sometimes update the forecasts correctly in real time but at other times will continue to show me an incorrect real time forecast. Having said that, I haven't found anything more accurate. Wish the pro was a one-time fee rather than recurring sub.

What's new

This release aims to fix a number of loading problems that can occur when network issues are encountered. The size of the app is now larger, however the extra size contains content the app no longer needs to fetch from the server. Overall this will decrease the amount of network traffic needed to load the app and significantly speed up and improve reliability of app load.
