# String.io vs Tornado.io!

The clearest difference is monetization model: Tornado.io! at free with in-app purchases against String.io's subscription. Tornado.io! also leads on update cadence (every 2 weeks vs every 3 months) and ratings volume (98K vs 1.8K). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. String.io sells 4 in-app purchases, starting at $7.99 per 7 days and Tornado.io! sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Tornado.io! holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Tornado.io! has 98K ratings behind it against 1.8K, so its average is the more settled of the two. Written reviews complicate that: 58% of String.io's written reviews are positive against 51% of Tornado.io!'s, so the app with the better star average is not the one people write more warmly about.

String.io ships an update every 3 months, Tornado.io! every 2 weeks. The most recent releases landed on October 7, 2026 and October 10, 2026 respectively.
