# CardWeb vs Wiki

The clearest difference is in-app purchases: Wiki at none against CardWeb's 2. Wiki also leads on iOS requirement (12.0 vs 18.0). CardWeb's advantage is ads (none vs shown) and update cadence (every 4 days vs fortnightly). On price and device support there is nothing between them.

Both are free to download. CardWeb sells 2 in-app purchases, starting at $19.99 per month. Wiki asks for nothing beyond the download.

CardWeb ships an update every 4 days, Wiki fortnightly. The most recent releases landed on October 27, 2026 and October 28, 2026 respectively.
