# Scheduler vs FireSync Shift Calendar

The clearest difference is price: FireSync Shift Calendar at Free against Scheduler's $7.99. FireSync Shift Calendar also leads on rating (4.8 vs 3.8) and ratings volume (9.1K vs 74). Scheduler's advantage is update cadence (every 9 days vs every 2 months) and chart position (#135 vs unranked). On ads, in-app purchases, monetization model and device support there is nothing between them.

FireSync Shift Calendar is free to download; Scheduler costs $7.99 up front. Neither carries in-app purchases, so what you see is what you pay.

FireSync Shift Calendar holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: FireSync Shift Calendar has 9.1K ratings behind it against 74, so its average is the more settled of the two. Written reviews complicate that: 79% of Scheduler's written reviews are positive against 69% of FireSync Shift Calendar's, so the app with the better star average is not the one people write more warmly about.

Scheduler ships an update every 9 days, FireSync Shift Calendar every 2 months. Both last shipped on October 13, 2026.
