Verdict

The call

The clearest difference is rating: ADHD at 2.9 against Apollo's 1.0. ADHD also leads on review sentiment (15% vs 0%) and ratings volume (7 vs 1). Apollo's advantage is in-app purchases (none vs 7) and update cadence (monthly vs every 3 months). On price, ads and device support there is nothing between them.
