Verdict
The clearest difference is in-app purchases: Adder at none against Easy Grade's 3. Adder also leads on ads (none vs shown) and iOS requirement (15.6 vs 17.6). Easy Grade's advantage is ratings volume (11K vs 1). On price, rating, update cadence and device support there is nothing between them.
