Verdict

The call

The clearest difference is ads: 100cm Ruler at none against 3D Snap's shown. 100cm Ruler also leads on review sentiment (45% vs 32%) and iOS requirement (12.0 vs 18.0). 3D Snap's advantage is ratings volume (408 vs 1) and update cadence (every 3 weeks vs every 3 months). On price, rating, in-app purchases and monetization model there is nothing between them.
