Verdict

The call

The clearest difference is price: Tiny Calendar at Free against Custom Alerts's $0.99. Tiny Calendar also leads on rating (4.6 vs 3.8) and update cadence (every 2 months vs every 13 months). Custom Alerts's advantage is in-app purchases (none vs 10) and ads (none vs shown). On device support there is nothing between them.
