Verdict
The clearest difference is price: Things at $6.99 against Agonizer's $19.99. Things also leads on in-app purchases (none vs 3) and review sentiment (100% vs 79%). Agonizer's advantage is ratings volume (203 vs 6) and update cadence (every 5 months vs every 17 months). On ads and device support there is nothing between them.
