Verdict

The call

The clearest difference is price: TaskRN at Free against ThirdCatheter's $1.99. TaskRN also leads on iOS requirement (13.0 vs 26.0). ThirdCatheter's advantage is review sentiment (100% vs 67%) and update cadence (every 4 days vs every 2 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
