# Chess vs Opening Prep

The clearest difference is in-app purchases: Opening Prep at none against Chess's 2. Opening Prep also leads on ads (none vs shown) and update cadence (every 4 days vs every 3 weeks). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Chess sells 2 in-app purchases, starting at $3.99 per month. Opening Prep asks for nothing beyond the download.

Chess ships an update every 3 weeks, Opening Prep every 4 days. The most recent releases landed on October 28, 2026 and October 24, 2026 respectively.
