Verdict
The clearest difference is rating: SymphonyLight at 2.2 against Smart Cover's 1.7. SymphonyLight also leads on ratings volume (106 vs 3) and iOS requirement (11.4 vs 13.0). Smart Cover's advantage is update cadence (weekly vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.
