Verdict
The clearest difference is in-app purchases: Phonics Inventory at none against The World Autistic's 2. Phonics Inventory also leads on iOS requirement (10.0 vs 15.0). The World Autistic's advantage is update cadence (fortnightly vs every 4 months) and device support (3 vs 1). On price and ads there is nothing between them.
