# Tiny Calendar vs One Calendar

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.

Both are free to download. Tiny Calendar sells 10 in-app purchases, starting at $1.49 per 7 days and One Calendar sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

One Calendar holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 21K and 21K respectively. Written reviews point the same way: 77% of Tiny Calendar's written reviews are positive against 81% of One Calendar's.

Tiny Calendar ships an update every 2 months, One Calendar fortnightly. Both last shipped on September 25, 2026.
