# Think vs FastMath

The clearest difference is ads: Think at none against FastMath's shown. FastMath's advantage is update cadence (every 2 weeks vs every 3 months) and device support (3 vs 1). On price and in-app purchases there is nothing between them.

Both are free to download. Think sells 1 one-off in-app purchase and FastMath sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Think ships an update every 3 months, FastMath every 2 weeks. Both last shipped on October 7, 2026.
