# Appointment King vs SignUpGenius

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.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

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.

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.
