Verdict
The clearest difference is rating: SendLynx at 5.0 against ECI Bolt's 2.7. SendLynx also leads on update cadence (every 3 days vs fortnightly). ECI Bolt's advantage is ratings volume (76 vs 1) and iOS requirement (16.0 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.
