# Calendars vs HiCal

The clearest difference is in-app purchases: HiCal at none against Calendars's 20. HiCal also leads on iOS requirement (13.0 vs 18.2). Calendars's advantage is ratings volume (122K vs 23) and update cadence (every 11 days vs every 2 months). On price, rating, review sentiment and ads there is nothing between them.

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

On the App Store both sit at effectively the same score — 4.7 for Calendars against 4.7 for HiCal. That said, the two scores are not equally well evidenced: Calendars has 122K ratings behind it against 23, so its average is the more settled of the two. Written reviews split almost evenly too, at 55% and 55% positive.

Calendars ships an update every 11 days, HiCal every 2 months. The most recent releases landed on September 25, 2026 and September 7, 2026 respectively.
