Verdict

The call

The clearest difference is price: Must at Free against Countdown's $9.99. Must also leads on update cadence (every 3 months vs every 7 months). Countdown's advantage is review sentiment (100% vs 91%). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
