Verdict
The clearest difference is in-app purchases: GM ChessPrep at none against Linear Algebra's 1. GM ChessPrep also leads on iOS requirement (15.0 vs 18.6). Linear Algebra's advantage is update cadence (every 2 days vs every 42 months). On price, ads and device support there is nothing between them.
