Verdict
The clearest difference is ads: Efelya at none against GestAge's shown. Efelya also leads on update cadence (fortnightly vs every 3 months). GestAge's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.4). On price, review sentiment, in-app purchases and monetization model there is nothing between them.
