Verdict

The call

The clearest difference is ads: Readlang Language Readers at none against Polyglot Reader's shown.

Polyglot Reader's advantage is ratings volume (74 vs 5) and iOS requirement (16.0 vs 18.0). On price, in-app purchases, monetization model and device support there is nothing between them.
