# ShiftLife Organizer vs Calendars

The clearest difference is ads: Calendars at none against ShiftLife Organizer's shown. Calendars also leads on ratings volume (122K vs 1.8K) and update cadence (every 11 days vs every 5 weeks). ShiftLife Organizer's advantage is review sentiment (78% vs 55%). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. ShiftLife Organizer sells 13 in-app purchases, starting at $1.99 per year and Calendars sells 18 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for ShiftLife Organizer against 4.7 for Calendars. That said, the two scores are not equally well evidenced: Calendars has 122K ratings behind it against 1.8K, so its average is the more settled of the two. Written reviews are what separate them: 78% of ShiftLife Organizer's written reviews are positive against 55% of Calendars's.

ShiftLife Organizer ships an update every 5 weeks, Calendars every 11 days. The most recent releases landed on September 22, 2026 and September 26, 2026 respectively.
