# Kaizen vs SlotFlow

The clearest difference is ads: Kaizen at none against SlotFlow's shown. Kaizen also leads on iOS requirement (13.0 vs 26.2). SlotFlow's advantage is update cadence (every 2 days vs every 8 months). On price, in-app purchases and device support there is nothing between them.

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

Kaizen ships an update every 8 months, SlotFlow every 2 days. The most recent releases landed on October 24, 2026 and September 23, 2026 respectively.
