# HarmoniQ vs Note Diver

The clearest difference is in-app purchases: Note Diver at none against HarmoniQ's 7. Note Diver also leads on rating (5.0 vs 4.8) and iOS requirement (14.0 vs 18.6). HarmoniQ's advantage is ratings volume (64 vs 2). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. HarmoniQ sells 7 in-app purchases, starting at $4.99 per month. Note Diver asks for nothing beyond the download.

Note Diver holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: HarmoniQ has 64 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on October 14, 2026 and October 1, 2026 respectively.
