Verdict
The clearest difference is price: Bobbin at Free against MySizer's $1.99. Bobbin also leads on update cadence (every 6 weeks vs every 38 months) and iOS requirement (17.0 vs 26.1). MySizer's advantage is in-app purchases (none vs 3). On review sentiment, ads and device support there is nothing between them.
