Verdict
The clearest difference is in-app purchases: eqSolver at none against Mechanical Formula's 1. eqSolver also leads on rating (5.0 vs 4.7) and iOS requirement (9.0 vs 13.0). Mechanical Formula's advantage is update cadence (every 4 months vs every 69 months) and ratings volume (34 vs 2). On price, ads and device support there is nothing between them.
