Verdict

The call

The clearest difference is in-app purchases: Equations at none against Studdy's 51. Equations also leads on iOS requirement (12.0 vs 15.0). Studdy's advantage is rating (4.8 vs 4.4) and update cadence (every 10 days vs every 2 months). On price, ads and device support there is nothing between them.
