# ColorLingo vs Iteratio

The clearest difference is rating: Iteratio at 5.0 against ColorLingo's 4.6. Iteratio also leads on update cadence (every 2 weeks vs every 5 weeks). ColorLingo's advantage is ratings volume (41 vs 1) and iOS requirement (15.0 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. ColorLingo sells 3 in-app purchases, starting at $5.99 per month and Iteratio sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

Iteratio holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: ColorLingo has 41 ratings behind it against 1, so its average is the more settled of the two.

ColorLingo ships an update every 5 weeks, Iteratio every 2 weeks. The most recent releases landed on October 25, 2026 and October 19, 2026 respectively.
