# Fisic vs Kaizer

The clearest difference is in-app purchases: Fisic at none against Kaizer's 11. Fisic also leads on ratings volume (60 vs 9). Kaizer's advantage is update cadence (every 10 days vs every 3 months). On price, rating, ads and device support there is nothing between them.

Both are free to download. Kaizer sells 11 in-app purchases, starting at $3.99 per 7 days. Fisic asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Fisic against 5.0 for Kaizer. That said, the two scores are not equally well evidenced: Fisic has 60 ratings behind it against 9, so its average is the more settled of the two.

Fisic ships an update every 3 months, Kaizer every 10 days. The most recent releases landed on September 21, 2026 and September 18, 2026 respectively.
