# CSI Pro vs WebDebug

The clearest difference is in-app purchases: CSI Pro at none against WebDebug's 3. CSI Pro also leads on iOS requirement (8.0 vs 12.0). WebDebug's advantage is update cadence (every 2 months vs every 12 months) and chart position (#199 vs unranked). On price, ads and device support there is nothing between them.

Both are free to download. WebDebug sells 3 in-app purchases, starting at $0.99 per 7 days. CSI Pro asks for nothing beyond the download.

CSI Pro ships an update every 12 months, WebDebug every 2 months. The most recent releases landed on September 16, 2026 and September 24, 2026 respectively.
