Verdict

The call

The clearest difference is update cadence: CONVERT UNITS at weekly against Convert's every 3 months. CONVERT UNITS also leads on ratings volume (1.4K vs 126) and monetization model (ad-supported vs freemium). Convert's advantage is iOS requirement (12.0 vs 15.0). On price, rating, review sentiment and ads there is nothing between them.
