# JSBox vs Algorithms

The clearest difference is rating: Algorithms at 4.5 against JSBox's 4.0. Algorithms also leads on review sentiment (79% vs 50%) and monetization model (free vs free with in-app purchases). JSBox's advantage is ratings volume (85 vs 8) and chart position (#69 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. JSBox sells 2 in-app purchases, starting at $7.99 per year and Algorithms sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Algorithms holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: JSBox has 85 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 50% of JSBox's written reviews are positive against 79% of Algorithms's.

JSBox ships an update fortnightly, Algorithms every 3 weeks. The most recent releases landed on September 24, 2026 and September 18, 2026 respectively.
