# Zero vs Colour Widgets

The clearest difference is rating: Zero at 4.8 against Colour Widgets's 4.2. Zero also leads on ratings volume (445K vs 33) and chart position (#116 vs unranked). Colour Widgets's advantage is in-app purchases (none vs 17) and update cadence (every 2 days vs every 2 weeks). On price, ads and device support there is nothing between them.

Both are free to download. Zero sells 10 in-app purchases, starting at $9.99 per month. Colour Widgets asks for nothing beyond the download.

Zero holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Zero has 445K ratings behind it against 33, so its average is the more settled of the two. Written reviews complicate that: 32% of Zero's written reviews are positive against 50% of Colour Widgets's, so the app with the better star average is not the one people write more warmly about.

Zero ships an update every 2 weeks, Colour Widgets every 2 days. The most recent releases landed on October 30, 2026 and October 25, 2026 respectively.
