# VKos vs Stack B

The clearest difference is rating: Stack B at 4.4 against VKos's 2.8. Stack B also leads on update cadence (every 5 days vs every 6 weeks) and review sentiment (93% vs 68%). VKos's advantage is ratings volume (132 vs 16). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. VKos sells 7 one-off in-app purchases and Stack B sells 1 in-app purchase, starting at $1.49 per month. Whichever you choose, the download price is not the number that matters.

Stack B holds the better App Store score, 4.4 against 2.8. That said, the two scores are not equally well evidenced: VKos has 132 ratings behind it against 16, so its average is the more settled of the two. Written reviews point the same way: 68% of VKos's written reviews are positive against 93% of Stack B's.

VKos ships an update every 6 weeks, Stack B every 5 days. The most recent releases landed on October 3, 2026 and October 2, 2026 respectively.
