# Grainfall vs Cavernum

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

Both are free to download. Grainfall sells 6 one-off in-app purchases and Cavernum sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Grainfall ships an update fortnightly, Cavernum every 2 days. The most recent releases landed on September 30, 2026 and October 8, 2026 respectively.
