# xCluster vs Max Calc

The clearest difference is rating: Max Calc at 5.0 against xCluster's 4.0. Max Calc also leads on update cadence (every 9 days vs every 3 weeks) and iOS requirement (17.0 vs 26.0). xCluster's advantage is in-app purchases (none vs 2) and ratings volume (5 vs 1). On price, review sentiment, ads and monetization model there is nothing between them.

Both are free to download. Max Calc sells 2 one-off in-app purchases. xCluster asks for nothing beyond the download.

Max Calc holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: xCluster has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

xCluster ships an update every 3 weeks, Max Calc every 9 days. The most recent releases landed on September 21, 2026 and June 4, 2026 respectively.
