# Opus One vs Edo Agenda

The clearest difference is rating: Opus One at 4.7 against Edo Agenda's 3.8. Opus One also leads on ratings volume (983 vs 104). Edo Agenda's advantage is monetization model (free with in-app purchases vs subscription) and iOS requirement (10.0 vs 15.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Opus One sells 2 in-app purchases, starting at $4.99 per month and Edo Agenda sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Opus One holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: Opus One has 983 ratings behind it against 104, so its average is the more settled of the two.
