# Stack AR vs Unseen AR

The clearest difference is rating: Stack AR at 3.8 against Unseen AR's 3.0. Stack AR also leads on ratings volume (2.1K vs 8) and review sentiment (32% vs 19%). Unseen AR's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 4 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Stack AR sells 1 one-off in-app purchase and Unseen AR sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Stack AR holds the better App Store score, 3.8 against 3.0. That said, the two scores are not equally well evidenced: Stack AR has 2.1K ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 32% of Stack AR's written reviews are positive against 19% of Unseen AR's.

Stack AR ships an update every 4 months, Unseen AR every 2 weeks. The most recent releases landed on October 7, 2026 and October 1, 2026 respectively.
