Verdict

The call

The clearest difference is review sentiment: Calculator # at 60% against Summary Scanner's 9%. Calculator # also leads on rating (4.6 vs 2.1) and ratings volume (36K vs 7). Summary Scanner's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.
