Verdict
The clearest difference is price: Scolio at Free against Scoliometer's $9.99. Scolio also leads on rating (5.0 vs 4.1) and iOS requirement (13.0 vs 15.0). Scoliometer's advantage is chart position (#158 vs unranked) and ratings volume (14 vs 2). On ads, in-app purchases, monetization model and device support there is nothing between them.
