# Zempy vs Microgram

The clearest difference is monetization model: Microgram at free with in-app purchases against Zempy's subscription. Microgram also leads on rating (4.7 vs 4.2) and ratings volume (1.1K vs 38). Zempy's advantage is update cadence (every 3 days vs every 2 weeks) and iOS requirement (13.0 vs 17.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Zempy sells 6 in-app purchases, starting at $9.99 per month and Microgram sells 10 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Microgram holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Microgram has 1.1K ratings behind it against 38, so its average is the more settled of the two. Written reviews point the same way: 63% of Zempy's written reviews are positive against 67% of Microgram's.

Zempy ships an update every 3 days, Microgram every 2 weeks. The most recent releases landed on August 31, 2026 and September 26, 2026 respectively.
