# Tooth Atlas 8 vs OneScreen

The clearest difference is in-app purchases: OneScreen at none against Tooth Atlas 8's 1. OneScreen also leads on rating (5.0 vs 4.7). Tooth Atlas 8's advantage is ratings volume (14 vs 1) and iOS requirement (8.4 vs 16.4). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Tooth Atlas 8 sells 1 one-off in-app purchase. OneScreen asks for nothing beyond the download.

OneScreen holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Tooth Atlas 8 has 14 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.

Tooth Atlas 8 ships an update fortnightly, OneScreen every 10 days. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
