# Essimu vs Call Scheduler

The clearest difference is ads: Essimu at none against Call Scheduler's shown. Essimu also leads on iOS requirement (12.4 vs 15.6). Call Scheduler's advantage is update cadence (every 8 days vs every 6 months). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Essimu sells 3 one-off in-app purchases and Call Scheduler sells 1 in-app purchase, starting at $9.99 per year. Whichever you choose, the download price is not the number that matters.

Essimu ships an update every 6 months, Call Scheduler every 8 days. The most recent releases landed on October 9, 2026 and October 13, 2026 respectively.
