# Kaizer vs STRYON

The clearest difference is update cadence: STRYON at every 3 days against Kaizer's every 8 days. Kaizer's advantage is ratings volume (9 vs 1). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Kaizer sells 11 in-app purchases, starting at $3.99 per 7 days and STRYON sells 2 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Kaizer against 5.0 for STRYON. That said, the two scores are not equally well evidenced: Kaizer has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Kaizer ships an update every 8 days, STRYON every 3 days. The most recent releases landed on October 24, 2026 and October 8, 2026 respectively.
