# Neptune vs PracNav

The clearest difference is in-app purchases: Neptune at none against PracNav's 1. Neptune also leads on ratings volume (17 vs 1) and device support (3 vs 1). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. PracNav sells 1 one-off in-app purchase. Neptune asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Neptune against 5.0 for PracNav. That said, the two scores are not equally well evidenced: Neptune has 17 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
