# Kinnu vs Micro Learning

The clearest difference is review sentiment: Kinnu at 87% against Micro Learning's 40%. Kinnu also leads on ads (none vs shown) and rating (4.8 vs 4.5). Micro Learning's advantage is ratings volume (55K vs 494) and chart position (#27 vs unranked). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Kinnu sells 4 in-app purchases, starting at $1.99 per month and Micro Learning sells 13 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Kinnu holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Micro Learning has 55K ratings behind it against 494, so its average is the more settled of the two. Written reviews point the same way: 87% of Kinnu's written reviews are positive against 40% of Micro Learning's.

Kinnu ships an update every 6 days, Micro Learning weekly. The most recent releases landed on September 22, 2026 and September 24, 2026 respectively.
