# Shikaku vs One Color!

The clearest difference is in-app purchases: Shikaku at none against One Color!'s 7. Shikaku also leads on review sentiment (76% vs 44%). One Color!'s advantage is rating (4.7 vs 4.4) and update cadence (every 4 days vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. One Color! sells 7 in-app purchases, starting at $4.99 per month. Shikaku asks for nothing beyond the download.

One Color! holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: One Color! has 249 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 76% of Shikaku's written reviews are positive against 44% of One Color!'s, so the app with the better star average is not the one people write more warmly about.

Shikaku ships an update every 3 weeks, One Color! every 4 days. The most recent releases landed on October 31, 2026 and November 5, 2026 respectively.
