Sea Legs Bluetooth also leads on update cadence (every 2 weeks vs every 4 months) and iOS requirement (9.3 vs 11.0). ZEFNET Charge's advantage is ratings volume (26 vs 3) and review sentiment (10% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.

Sea Legs Bluetooth holds the better App Store score, 2.3 against 1.6. That said, the two scores are not equally well evidenced: ZEFNET Charge has 26 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 10% of ZEFNET Charge's written reviews are positive against 0% of Sea Legs Bluetooth's, so the app with the better star average is not the one people write more warmly about.
