# kubic vs 4=10

The clearest difference is review sentiment: 4=10 at 98% against kubic's 36%. 4=10 also leads on rating (4.9 vs 4.4) and ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. kubic sells 5 one-off in-app purchases and 4=10 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

4=10 holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: 4=10 has 2.5K ratings behind it against 245, so its average is the more settled of the two. Written reviews point the same way: 36% of kubic's written reviews are positive against 98% of 4=10's.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 9, 2026 and September 20, 2026 respectively.
