# Kmap vs Fx Minimizer

The clearest difference is rating: Kmap at 5.0 against Fx Minimizer's 1.0. Kmap also leads on in-app purchases (none vs 1) and ratings volume (5 vs 1). Fx Minimizer's advantage is update cadence (every 20 months vs every 128 months) and iOS requirement (9.0 vs 15.1). On price, ads and device support there is nothing between them.

Both are free to download. Fx Minimizer sells 1 one-off in-app purchase. Kmap asks for nothing beyond the download.

Kmap holds the better App Store score, 5.0 against 1.0. That said, the two scores are not equally well evidenced: Kmap has 5 ratings behind it against 1, so its average is the more settled of the two.

Kmap ships an update every 128 months, Fx Minimizer every 20 months. The most recent releases landed on June 1, 2026 and September 16, 2026 respectively.
