# Calcium vs Microgram

The clearest difference is rating: Microgram at 4.7 against Calcium's 3.7. Microgram also leads on update cadence (every 2 weeks vs every 3 months) and ratings volume (1.1K vs 3). Calcium's advantage is review sentiment (100% vs 65%) and in-app purchases (none vs 11). On price and ads there is nothing between them.

Both are free to download. Microgram sells 10 in-app purchases, starting at $9.99 per month. Calcium asks for nothing beyond the download.

Microgram holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Microgram has 1.1K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Calcium's written reviews are positive against 65% of Microgram's, so the app with the better star average is not the one people write more warmly about.

Calcium ships an update every 3 months, Microgram every 2 weeks. The most recent releases landed on October 24, 2026 and October 30, 2026 respectively.
