# MyCal vs Formula

The clearest difference is in-app purchases: Formula at none against MyCal's 3. Formula also leads on ads (none vs shown). MyCal's advantage is update cadence (every 4 days vs fortnightly) and iOS requirement (15.1 vs 17.0). On price and device support there is nothing between them.

Both are free to download. MyCal sells 3 in-app purchases, starting at $4.99 per month. Formula asks for nothing beyond the download.

MyCal ships an update every 4 days, Formula fortnightly. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
