# Date and Time Calculator vs PDPM Navigator®

The clearest difference is ads: PDPM Navigator® at none against Date and Time Calculator's shown. PDPM Navigator® also leads on review sentiment (100% vs 81%) and monetization model (free vs ad-supported). Date and Time Calculator's advantage is rating (4.7 vs 4.2) and ratings volume (9.9K vs 13). On price, update cadence, 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.

Date and Time Calculator holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Date and Time Calculator has 9.9K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 81% of Date and Time Calculator's written reviews are positive against 100% of PDPM Navigator®'s, so the app with the better star average is not the one people write more warmly about.

Date and Time Calculator ships an update every 4 weeks, PDPM Navigator® every 2 months. The most recent releases landed on October 27, 2026 and October 25, 2026 respectively.
