DeXeF views DXF files on Apple devices. Open a drawing and pan, zoom, and read off coordinates against a reference grid, with every layer just a toggle away. On macOS, DeXeF also provides Quick Look previews and Finder thumbnails, so you can peek at a DXF file without opening the app. There are many DXF viewers on the App Store, but all of them are terrible and cost too much. This one is free, low on mystery meat, and hopefully broadly functional.

Verdict
The clearest difference is ads: DeXeF at none against CADFast's shown. DeXeF also leads on device support (3 vs 1). CADFast's advantage is update cadence (every 3 weeks vs every 2 months) and iOS requirement (16.0 vs 26.0). On price and in-app purchases there is nothing between them.
