# chmod vs SysOpsKit

The clearest difference is in-app purchases: chmod at none against SysOpsKit's 1. chmod also leads on iOS requirement (8.2 vs 15.6). SysOpsKit's advantage is update cadence (every 3 days vs every 5 months). On price, ads and device support there is nothing between them.

Both are free to download. SysOpsKit sells 1 in-app purchase, starting at $1.99 per month. chmod asks for nothing beyond the download.

chmod ships an update every 5 months, SysOpsKit every 3 days. The most recent releases landed on September 27, 2026 and October 4, 2026 respectively.
