Yes, that’s my understanding. So it’s more work to use than point and shoot, which would be a nice feature for someone like me who can recognize major constellations and planets, but not much else.

Planisphere is alright, it’s basic, but does the job. No nasties in it and works offline.

Tubular has sponsor block too.

Do you mean Heliboard? It supports gesture typing, but you need to import the library you want.
