# DoCube vs Focus Gacha

The clearest difference is rating: Focus Gacha at 5.0 against DoCube's 4.6. Focus Gacha also leads on update cadence (every 6 days vs every 3 weeks). DoCube's advantage is ratings volume (11 vs 2) and device support (3 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. DoCube sells 1 one-off in-app purchase and Focus Gacha sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Focus Gacha holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: DoCube has 11 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

DoCube ships an update every 3 weeks, Focus Gacha every 6 days. The most recent releases landed on October 6, 2026 and October 10, 2026 respectively.
