Verdict
The clearest difference is ads: Fit by Wix at none against [solidcore]'s shown. Fit by Wix also leads on review sentiment (47% vs 21%) and monetization model (free vs free with in-app purchases). [solidcore]'s advantage is chart position (#156 vs unranked) and ratings volume (29K vs 4.1K). On price, rating, in-app purchases and iOS requirement there is nothing between them.
