Verdict

The call

The clearest difference is rating: Appointment King at 1.9 against SignUpGenius's 1.3. Appointment King also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). SignUpGenius's advantage is ratings volume (157 vs 14) and update cadence (every 4 months vs every 10 months). On price, review sentiment, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Appointment King holds the better App Store score, 1.9 against 1.3. That said, the two scores are not equally well evidenced: SignUpGenius has 157 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 0% of Appointment King's written reviews are positive against 2% of SignUpGenius's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Appointment King ships an update every 10 months, SignUpGenius every 4 months. The most recent releases landed on November 2, 2026 and November 6, 2026 respectively.
