# GT Graph vs Lie group

The clearest difference is in-app purchases: Lie group at none against GT Graph's 1. Lie group also leads on iOS requirement (16.6 vs 18.0). GT Graph's advantage is device support. On price there is nothing between them.

Both are free to download. GT Graph sells 1 one-off in-app purchase. Lie group asks for nothing beyond the download.
