Fitdays+ holds the better App Store score, 4.4 against 2.7. That said, the two scores are not equally well evidenced: Fitdays+ has 836 ratings behind it against 133, so its average is the more settled of the two. Written reviews complicate that: 21% of Scale Up's written reviews are positive against 16% of Fitdays+'s, so the app with the better star average is not the one people write more warmly about.
Scale Up ships an update every 2 months, Fitdays+ every 3 weeks. The most recent releases landed on October 23, 2026 and October 27, 2026 respectively.
