# Kmap vs Math Automata

The clearest difference is in-app purchases: Kmap at none against Math Automata's 1. Kmap also leads on ads (none vs shown). Math Automata's advantage is update cadence (every 4 days vs every 128 months) and iOS requirement (13.0 vs 15.1). On price and device support there is nothing between them.

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

Kmap ships an update every 128 months, Math Automata every 4 days. The most recent releases landed on June 1, 2026 and September 21, 2026 respectively.
