Verdict
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.

Both are free to download. ADHD sells 7 in-app purchases, starting at $4.99 per month. Apollo asks for nothing beyond the download.
ADHD holds the better App Store score, 2.9 against 1.0. That said, the two scores are not equally well evidenced: ADHD has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 15% of ADHD's written reviews are positive against 0% of Apollo's.
ADHD ships an update every 3 months, Apollo monthly. The most recent releases landed on September 23, 2026 and September 20, 2026 respectively.
