Verdict

The call

The clearest difference is rating: Calculator Max at 4.3 against Lookmark's 3.6. Calculator Max also leads on ads (none vs shown) and ratings volume (1.8K vs 83). Lookmark's advantage is update cadence (every 8 days vs every 2 months). On price, review sentiment, in-app purchases and monetization model there is nothing between them.
