Verdict

The call

The clearest difference is in-app purchases: Gradus¹ at none against Days's 19. Gradus¹ also leads on iOS requirement (9.0 vs 17.0). Days's advantage is update cadence (every 5 days vs every 3 months) and ratings volume (12K vs 6). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Days sells 14 in-app purchases, starting at $0.99 per month. Gradus¹ asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Days holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Days has 12K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 73% of Days's written reviews are positive against 77% of Gradus¹'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Days ships an update every 5 days, Gradus¹ every 3 months. The most recent releases landed on October 1, 2026 and September 16, 2026 respectively.
