# Period vs Monthly

The clearest difference is in-app purchases: Monthly at none against Period's 1. Monthly also leads on ads (none vs shown) and update cadence (every 4 days vs monthly). Period's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 26.0). On price there is nothing between them.

Both are free to download. Period sells 1 one-off in-app purchase. Monthly asks for nothing beyond the download.

Period ships an update monthly, Monthly every 4 days. The most recent releases landed on October 27, 2026 and October 28, 2026 respectively.
