Verdict
The clearest difference is rating: Matrix Operations at 4.7 against Fx Minimizer's 1.0. Matrix Operations also leads on update cadence (every 10 days vs every 20 months) and ratings volume (19 vs 1). Fx Minimizer's advantage is ads (none vs shown) and iOS requirement (9.0 vs 15.5). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Fx Minimizer sells 1 one-off in-app purchase and Matrix Operations sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Matrix Operations holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Matrix Operations has 19 ratings behind it against 1, so its average is the more settled of the two.
Fx Minimizer ships an update every 20 months, Matrix Operations every 10 days. The most recent releases landed on September 16, 2026 and September 24, 2026 respectively.
