# Mastersoft Chess vs Chess Prep Pro Openings

The clearest difference is ratings volume: Mastersoft Chess at 1.5K against Chess Prep Pro Openings's 20. Mastersoft Chess also leads on review sentiment (90% vs 74%) and update cadence (every 5 days vs fortnightly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Mastersoft Chess sells 3 in-app purchases, starting at $2.99 per month and Chess Prep Pro Openings sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
