# Z vs FlexBeam

The clearest difference is rating: Z at 4.8 against FlexBeam's 1.0. Z also leads on ratings volume (433 vs 1). FlexBeam's advantage is update cadence (every 9 days vs every 2 months) and review sentiment (100% vs 83%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Z holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: Z has 433 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 83% of Z's written reviews are positive against 100% of FlexBeam's, so the app with the better star average is not the one people write more warmly about.

Z ships an update every 2 months, FlexBeam every 9 days. The most recent releases landed on September 22, 2026 and September 10, 2026 respectively.
