# Attendance Radar vs Ludus

The clearest difference is rating: Ludus at 5.0 against Attendance Radar's 3.7. Attendance Radar's advantage is device support (3 vs 1). On price, review sentiment, ratings volume and update cadence there is nothing between them.

Both are free to download. Attendance Radar sells 2 in-app purchases, starting at $15.00 per month and Ludus sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

Ludus holds the better App Store score, 5.0 against 3.7. Both are backed by a comparable volume of ratings — 12 and 17 respectively. Written reviews complicate that: 90% of Attendance Radar's written reviews are positive against 87% of Ludus's, so the app with the better star average is not the one people write more warmly about.

Attendance Radar ships an update weekly, Ludus every 5 days. Both last shipped on September 29, 2026.
