# NIH Toolbox vs MyCap Classic

The clearest difference is rating: MyCap Classic at 4.2 against NIH Toolbox's 1.0. MyCap Classic also leads on in-app purchases (none vs 4) and ratings volume (11 vs 1). NIH Toolbox's advantage is review sentiment (100% vs 60%). 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. MyCap Classic asks for nothing beyond the download.

MyCap Classic holds the better App Store score, 4.2 against 1.0. That said, the two scores are not equally well evidenced: MyCap Classic has 11 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 60% of MyCap Classic'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, MyCap Classic every 2 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
