Verdict

The call

The clearest difference is ads: Lingo7 at none against Polyglot Reader's shown. Lingo7 also leads on review sentiment (100% vs 66%) and update cadence (every 2 days vs every 5 weeks). Polyglot Reader's advantage is ratings volume (74 vs 6). On price, in-app purchases, monetization model and device support there is nothing between them.
