# Art Hidden Objects vs Harmonium Pro HD

The clearest difference is rating: Art Hidden Objects at 4.5 against Harmonium Pro HD's 2.2. Harmonium Pro HD's advantage is ads (none vs shown) and update cadence (every 2 months vs every 30 months). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Art Hidden Objects sells 4 one-off in-app purchases and Harmonium Pro HD sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Art Hidden Objects holds the better App Store score, 4.5 against 2.2. Both are backed by a comparable volume of ratings — 2 and 5 respectively. Written reviews complicate that: 0% of Art Hidden Objects's written reviews are positive against 11% of Harmonium Pro HD's, so the app with the better star average is not the one people write more warmly about.

Art Hidden Objects ships an update every 30 months, Harmonium Pro HD every 2 months. The most recent releases landed on October 18, 2026 and November 1, 2026 respectively.
