# Matrix math calculator vs Linear Interpolation Master

The clearest difference is rating: Linear Interpolation Master at 4.7 against Matrix math calculator's 1.5. Linear Interpolation Master also leads on ratings volume (176 vs 2) and iOS requirement (11.0 vs 13.0). Matrix math calculator's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

Both are free to download. Linear Interpolation Master sells 3 one-off in-app purchases. Matrix math calculator asks for nothing beyond the download.

Linear Interpolation Master holds the better App Store score, 4.7 against 1.5. That said, the two scores are not equally well evidenced: Linear Interpolation Master has 176 ratings behind it against 2, so its average is the more settled of the two.

Matrix math calculator ships an update every 3 months, Linear Interpolation Master every 5 months. The most recent releases landed on September 13, 2026 and September 22, 2026 respectively.
