Verdict

The call

The clearest difference is rating: OnSkin at 4.7 against Solid Core's 1.0. OnSkin also leads on update cadence (every 2 weeks vs every 14 months) and ratings volume (33K vs 1). Solid Core's advantage is in-app purchases (none vs 15) and ads (none vs shown). On price and device support there is nothing between them.
