# The Marimo vs ケサランパサラン

The clearest difference is rating: The Marimo at 4.4 against ケサランパサラン's 1.0. The Marimo also leads on ratings volume (16 vs 1). ケサランパサラン's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 3 months). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

The Marimo holds the better App Store score, 4.4 against 1.0. That said, the two scores are not equally well evidenced: The Marimo has 16 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 80% of The Marimo's written reviews are positive against 86% of ケサランパサラン's, so the app with the better star average is not the one people write more warmly about.

The Marimo ships an update every 3 months, ケサランパサラン every 2 weeks. The most recent releases landed on October 19, 2026 and October 18, 2026 respectively.
