Verdict

The call

The clearest difference is rating: BetterUp at 4.5 against SLII®'s 3.3. BetterUp also leads on ratings volume (436 vs 28) and update cadence (weekly vs every 3 weeks). SLII®'s advantage is monetization model (free vs free with in-app purchases) and review sentiment (58% vs 42%). On price, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

BetterUp holds the better App Store score, 4.5 against 3.3. That said, the two scores are not equally well evidenced: BetterUp has 436 ratings behind it against 28, so its average is the more settled of the two. Written reviews complicate that: 58% of SLII®'s written reviews are positive against 42% of BetterUp's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

SLII® ships an update every 3 weeks, BetterUp weekly. The most recent releases landed on September 10, 2026 and September 20, 2026 respectively.
