Verdict
The clearest difference is price: Linear Algebra at Free against iSolveModel's $9.99. Linear Algebra also leads on update cadence (every 6 weeks vs every 4 months). iSolveModel's advantage is ads (none vs shown). On in-app purchases, device support and iOS requirement there is nothing between them.
