NIH Score & stroke tools holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: NIH Score & stroke tools has 69 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 25% of NIH Score & stroke tools's written reviews are positive against 43% of RapidAI's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

NIH Score & stroke tools ships an update every 5 months, RapidAI every 2 weeks. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
