# Calendars vs Krellot

The clearest difference is in-app purchases: Krellot at none against Calendars's 10. Krellot also leads on iOS requirement (16.4 vs 18.2). Calendars's advantage is chart position (#141 vs unranked) and device support (4 vs 1). On price and ads there is nothing between them.

Both are free to download. Calendars sells 10 in-app purchases, starting at $3.99 per month. Krellot asks for nothing beyond the download.
