# Polyhedra vs Master RPG AI

The clearest difference is rating: Polyhedra at 5.0 against Master RPG AI's 4.0. Polyhedra also leads on in-app purchases (none vs 5) and ads (none vs shown). Master RPG AI's advantage is update cadence (every 9 days vs every 2 months) and ratings volume (5 vs 1). On price, review sentiment and device support there is nothing between them.

Both are free to download. Master RPG AI sells 5 in-app purchases, starting at $6.99 per month. Polyhedra asks for nothing beyond the download.

Polyhedra holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Master RPG AI has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Polyhedra ships an update every 2 months, Master RPG AI every 9 days. The most recent releases landed on November 1, 2026 and November 5, 2026 respectively.
