Verdict
The clearest difference is monetization model: Theradynamics at free against KIRO's subscription. Theradynamics also leads on iOS requirement (13.0 vs 16.4). KIRO's advantage is ratings volume (25 vs 1) and update cadence (every 2 weeks vs every 5 weeks). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Theradynamics holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: KIRO has 25 ratings behind it against 1, so its average is the more settled of the two.
Theradynamics ships an update every 5 weeks, KIRO every 2 weeks. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
