# Opus One vs Adonit One

The clearest difference is rating: Opus One at 4.7 against Adonit One's 2.7. Opus One also leads on ratings volume (978 vs 9) and review sentiment (66% vs 47%). Adonit One's advantage is monetization model (free with in-app purchases vs subscription) and iOS requirement (13.4 vs 15.0).

Both are free to download. Opus One sells 2 in-app purchases, starting at $4.99 per month and Adonit One sells 4 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.
