Verdict
The clearest difference is in-app purchases: Spatial Ability Assessment at none against PolyFill's 3. Spatial Ability Assessment also leads on ads (none vs shown) and iOS requirement (10.0 vs 14.0). PolyFill's advantage is update cadence (every 6 months vs every 12 months). On price and device support there is nothing between them.
