# kubic vs Prisms

The clearest difference is review sentiment: Prisms at 89% against kubic's 36%. Prisms also leads on rating (4.9 vs 4.4) and ads (none vs shown). kubic's advantage is update cadence (every 2 months vs every 17 months) and ratings volume (245 vs 19). On price, in-app purchases, monetization model and device support there is nothing between them.

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

Prisms holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: kubic has 245 ratings behind it against 19, 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 89% of Prisms's.

kubic ships an update every 2 months, Prisms every 17 months. The most recent releases landed on September 28, 2026 and June 5, 2026 respectively.
