# Simple Moon Phase Calendar vs MOON Pro

The clearest difference is update cadence: MOON Pro at weekly against Simple Moon Phase Calendar's every 5 months. MOON Pro also leads on review sentiment (90% vs 65%) and device support (3 vs 1). Simple Moon Phase Calendar's advantage is rating (4.8 vs 4.4). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Simple Moon Phase Calendar sells 2 one-off in-app purchases and MOON Pro sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Simple Moon Phase Calendar holds the better App Store score, 4.8 against 4.4. Both are backed by a comparable volume of ratings — 86 and 69 respectively. Written reviews complicate that: 65% of Simple Moon Phase Calendar's written reviews are positive against 90% of MOON Pro's, so the app with the better star average is not the one people write more warmly about.

Simple Moon Phase Calendar ships an update every 5 months, MOON Pro weekly. The most recent releases landed on November 3, 2026 and October 27, 2026 respectively.
