# 100Days vs Pday

The clearest difference is rating: Pday at 5.0 against 100Days's 2.3. Pday also leads on ratings volume (19 vs 3) and device support (3 vs 1). 100Days's advantage is update cadence (daily vs every 3 days). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 100Days sells 3 in-app purchases, starting at $14.99 per month and Pday sells 1 in-app purchase, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

Pday holds the better App Store score, 5.0 against 2.3. That said, the two scores are not equally well evidenced: Pday has 19 ratings behind it against 3, so its average is the more settled of the two.

100Days ships an update daily, Pday every 3 days. Both last shipped on October 24, 2026.
