# Neptune vs Binnacle School

The clearest difference is in-app purchases: Neptune at none against Binnacle School's 3. Neptune also leads on ratings volume (15 vs 1) and iOS requirement (15.0 vs 17.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Binnacle School sells 3 in-app purchases, starting at $4.99 per month. 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 Binnacle School. That said, the two scores are not equally well evidenced: Neptune has 15 ratings behind it against 1, so its average is the more settled of the two.

Neptune ships an update every 4 days, Binnacle School weekly. The most recent releases landed on October 10, 2026 and September 30, 2026 respectively.
