# HarmoniQ vs One Thing Explained

The clearest difference is ratings volume: HarmoniQ at 65 against One Thing Explained's 5. On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. HarmoniQ sells 7 in-app purchases, starting at $4.99 per month and One Thing Explained sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

One Thing Explained holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: HarmoniQ has 65 ratings behind it against 5, 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 every 9 days. The most recent releases landed on October 22, 2026 and October 2, 2026 respectively.
