# Down to Zero vs Chess Move

The clearest difference is review sentiment: Down to Zero at 100% against Chess Move's 27%. Down to Zero also leads on rating (5.0 vs 4.3). Chess Move's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 3 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Down to Zero sells 1 one-off in-app purchase and Chess Move sells 10 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Down to Zero holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Chess Move has 1.1K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Down to Zero's written reviews are positive against 27% of Chess Move's.

Down to Zero ships an update every 3 months, Chess Move every 3 weeks. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
