We don't have labels on the walls at Mona. We have the O. The O uses location awareness to locate you in and around the museum. Use it to find out about artworks nearby, food and drink options, music performances, and other stuff. Love or hate what you see, join virtual queues and wander off, save your visit, and read and listen in your language. Think of the O as your own personal visitor guide at Mona. The O is also how you navigate the Phrontisterion, Mona's library. It replaces Dewey — charting a course through the collection and linking books by association, theme, or obscure whim. Point the camera at any book cover and reveal myriad connections to other items. Search by title, subject, or curiosity. Follow a thread from one book to another, and then somewhere you didn't expect to end up. The O knows where everything is and will take you there.

Verdict
The clearest difference is rating: The O at 3.5 against Uist's 1.0. The O also leads on update cadence (fortnightly vs every 5 weeks) and ratings volume (6 vs 1). Uist's advantage is review sentiment (50% vs 23%) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
The O holds the better App Store score, 3.5 against 1.0. That said, the two scores are not equally well evidenced: The O has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 23% of The O's written reviews are positive against 50% of Uist's, so the app with the better star average is not the one people write more warmly about.
The O ships an update fortnightly, Uist every 5 weeks. The most recent releases landed on October 15, 2026 and October 7, 2026 respectively.
