# Calendars vs Aapi

The clearest difference is in-app purchases: Aapi at none against Calendars's 20. Aapi also leads on iOS requirement (11.0 vs 18.2). Calendars's advantage is update cadence (every 11 days vs every 6 weeks) and chart position (#105 vs unranked). On price, ads and device support there is nothing between them.

Both are free to download. Calendars sells 18 in-app purchases, starting at $3.99 per month. Aapi asks for nothing beyond the download.

Calendars ships an update every 11 days, Aapi every 6 weeks. The most recent releases landed on September 24, 2026 and March 3, 2026 respectively.
