Steep Priced Solar Data
If you are a solar astronomer, and have somewhat deep pockets to put out for an Apple-based app, this utility provides very good data in a clean graphic presentation. It is unfortunate, especially for the price of 10 USD (as of this writing, 2016,10Feb:1919), this app provides none of the latest solar videos available [one of the reasons I keep the FREE Korean Solar Space Centers RRA SWx for Apple devices].
Because the steep price and the unavailability of videos of solar activity: 4 Stars.
