Verdict

The call

The clearest difference is monetization model: Shift Calendar at free with in-app purchases against Shift Work Calendar's subscription. Shift Calendar also leads on review sentiment (88% vs 67%) and iOS requirement (17.0 vs 26.0). Shift Work Calendar's advantage is rating (5.0 vs 4.7) and update cadence (every 2 days vs weekly). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Shift Work Calendar sells 2 in-app purchases, starting at $1.49 per month and Shift Calendar sells 10 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Shift Work Calendar holds the better App Store score, 5.0 against 4.7. Both are backed by a comparable volume of ratings — 5 and 3 respectively. Written reviews complicate that: 67% of Shift Work Calendar's written reviews are positive against 88% of Shift Calendar's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Shift Work Calendar ships an update every 2 days, Shift Calendar weekly. The most recent releases landed on October 24, 2026 and October 20, 2026 respectively.
