Letterly and Comet both sit at 4.7 stars, but that hides the real split: 78% of Letterly's written reviews are positive against 65% of Comet's. Letterly also leads on device support (4 vs 2) and iOS requirement (16.0 vs 18.0). Comet's advantage is ratings volume (7.8K vs 1.1K). On price, rating, update cadence and ads there is nothing between them.
