On iPad if you just want to do planetarium there is something like Distant Suns, SkyOrbs, …

The big advantage, in particular of the Pro edition (but not only), is the well-stocked basic catalog, the control of goto mounts, and the abundance of “skylists” which can be made by everyone and which deal with all themes: asterisms, Caldwell objects, improbable micro tâchouilles… there is something for everyone. It is sometimes on sale at -50% on the AppStore, watch for the occasion.
