Verdict
The clearest difference is update cadence: X at every 3 weeks against Engage SSF's every 3 months. X also leads on ratings volume (3.3K vs 68) and review sentiment (91% vs 71%). On price, rating, ads and in-app purchases there is nothing between them.

X holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: X has 3.3K ratings behind it against 68, so its average is the more settled of the two. Written reviews point the same way: 71% of Engage SSF's written reviews are positive against 91% of X's.
Engage SSF ships an update every 3 months, X every 3 weeks. The most recent releases landed on October 8, 2026 and October 17, 2026 respectively.
