# Caterpillar vs Micro Learning

The clearest difference is ads: Caterpillar at none against Micro Learning's shown. Caterpillar also leads on rating (5.0 vs 4.7) and update cadence (weekly vs fortnightly). Micro Learning's advantage is ratings volume (15 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Caterpillar sells 1 in-app purchase, starting at $4.99 per 7 days and Micro Learning sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Caterpillar holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Micro Learning has 15 ratings behind it against 1, so its average is the more settled of the two.

Caterpillar ships an update weekly, Micro Learning fortnightly. The most recent releases landed on October 10, 2026 and October 24, 2026 respectively.
