Great to know which moon is which. Needs update.

Great for knowing which moon is which when you are looking at Jupiter through a telescope. I wish that in addition to adding and subtracting time to see the progression of the moons that I could enter in a date and time to see where the moons are then. I am also sad that since the app is not updated, it will not work with iOS 11.
Useful but lacks features

The app plots the current moon positions and allows the user to jump back and forth in time. It doesn't make graphs of the positions over time and doesn't predict events such as transits. The GRS transits over the next few hours are shown. It would be nice if the app plotted the planet's elevation in the sky and gave time of meridian crossing. Despite being simple, it is useful. Thanks!
Does what I was looking for!

I was looking for something that would show me which moons where which when looking through my telescope. This did the job perfectly. Could it include more features? Sure. But it does exactly what I was looking for. The inclusion of shadows on Jupiter during moon transits was a very nice touch! Please make one for Saturn!!! :)
It does what it says

The app does a pretty good job at predicting the GRS on Jupiter and the positions of the 4 major moons. Pretty straight forward and simple. I would have given it a 5 star rating however there is a mis-spelling in the app on one of the Jupiter moons.
Superb! Fast to open; has key displays; three suggestions

Simple, fast, and useful. Not sure what the paid $ apps that present Jove's moons have that this doesn't. Would be even better if: 1) It had a video mode for the moons rather than just step mode (min, hours, days). 2) It showed moons in the Red spot close up screen, too. After all, the button says "Details". 3) It included eclipses, transits, too.
No one can say this is bad
