# Grains vs ArrowForge

The clearest difference is price: ArrowForge at Free against Grains's $1.99. ArrowForge also leads on rating (5.0 vs 4.3) and update cadence (fortnightly vs every 32 months). Grains's advantage is in-app purchases (none vs 2) and chart position (#196 vs unranked). On ads there is nothing between them.

ArrowForge is free to download; Grains costs $1.99 up front. ArrowForge sells 2 in-app purchases, starting at $6.99 per month. Grains asks for nothing beyond the download.

ArrowForge holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Grains has 6 ratings behind it against 1, so its average is the more settled of the two.

Grains ships an update every 32 months, ArrowForge fortnightly. The most recent releases landed on October 27, 2026 and October 15, 2026 respectively.
