# Wiki vs Kaizen

The clearest difference is in-app purchases: Wiki at none against Kaizen's 3. Wiki also leads on update cadence (fortnightly vs every 11 months) and iOS requirement (12.0 vs 16.4). Kaizen's advantage is ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Kaizen sells 3 in-app purchases, starting at $5.99 per 7 days. Wiki asks for nothing beyond the download.

Wiki ships an update fortnightly, Kaizen every 11 months. The most recent releases landed on October 28, 2026 and October 30, 2026 respectively.
