Verdict

The call

The clearest difference is in-app purchases: OddBook Universe at none against solAR's 1. OddBook Universe also leads on review sentiment (100% vs 67%) and rating (5.0 vs 4.6). solAR's advantage is ratings volume (2.1K vs 8) and iOS requirement (14.0 vs 17.0). On price, ads and device support there is nothing between them.
