The clearest difference is ads: DX FAITH at none against MathGrid 100's shown. DX FAITH also leads on device support (4 vs 2) and iOS requirement (13.4 vs 15.1). MathGrid 100's advantage is update cadence (every 3 weeks vs every 2 months). On price and in-app purchases there is nothing between them.
