Verdict

The call

The clearest difference is rating: Calculator⁼ at 4.6 against Draw's 1.7. Calculator⁼ also leads on ratings volume (359K vs 12) and review sentiment (36% vs 27%). Draw's advantage is ads (none vs shown) and iOS requirement (7.0 vs 15.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.
