# ColorWiz vs Arduino Programming Tutorial

The clearest difference is rating: ColorWiz at 4.3 against Arduino Programming Tutorial's 3.0. ColorWiz also leads on ads (none vs shown) and monetization model (free vs ad-supported). Arduino Programming Tutorial's advantage is update cadence (every 6 weeks vs every 10 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

ColorWiz holds the better App Store score, 4.3 against 3.0. That said, the two scores are not equally well evidenced: ColorWiz has 6 ratings behind it against 1, so its average is the more settled of the two.

ColorWiz ships an update every 10 months, Arduino Programming Tutorial every 6 weeks. Both last shipped on November 3, 2026.
