# NIH Toolbox vs Inquisit Player

The clearest difference is review sentiment: NIH Toolbox at 100% against Inquisit Player's 33%. Inquisit Player's advantage is rating (3.7 vs 1.0) and in-app purchases (none vs 4). On price, update cadence and ads there is nothing between them.

Both are free to download. NIH Toolbox sells 4 in-app purchases, starting at $0.99 per 7 days. Inquisit Player asks for nothing beyond the download.

Inquisit Player holds the better App Store score, 3.7 against 1.0. That said, the two scores are not equally well evidenced: Inquisit Player has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of NIH Toolbox's written reviews are positive against 33% of Inquisit Player's, so the app with the better star average is not the one people write more warmly about.

NIH Toolbox ships an update every 4 months, Inquisit Player every 2 months. The most recent releases landed on November 1, 2026 and November 7, 2026 respectively.
