Verdict
The clearest difference is monetization model: One Calendar at free with in-app purchases against Tiny Calendar's subscription. One Calendar also leads on ads (none vs shown) and update cadence (fortnightly vs every 2 months). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.
