# AutoCAD vs FlowAnalyzer Viewer

The clearest difference is iOS requirement: FlowAnalyzer Viewer at 15.0 against AutoCAD's 17.0. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. AutoCAD sells 3 in-app purchases, starting at $9.99 per month and FlowAnalyzer Viewer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 2 months. Both last shipped on October 21, 2026.
