Verdict

The call

The clearest difference is review sentiment: Calculator # at 60% against Solid Edge Mobile Viewer's 13%. Calculator # also leads on rating (4.6 vs 3.0) and ratings volume (36K vs 3). Solid Edge Mobile Viewer's advantage is in-app purchases (none vs 6) and ads (none vs shown). On price and update cadence there is nothing between them.
