# QUBE(큐브) vs 풀다

The clearest difference is review sentiment: 풀다 at 90% against QUBE(큐브)'s 58%. 풀다 also leads on update cadence (every 4 days vs every 3 weeks) and ratings volume (16 vs 1). QUBE(큐브)'s advantage is rating (5.0 vs 4.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. QUBE(큐브) sells 2 one-off in-app purchases and 풀다 sells 23 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

QUBE(큐브) holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: 풀다 has 16 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 58% of QUBE(큐브)'s written reviews are positive against 90% of 풀다's, so the app with the better star average is not the one people write more warmly about.

QUBE(큐브) ships an update every 3 weeks, 풀다 every 4 days. Both last shipped on September 21, 2026.
