Verdict
The clearest difference is review sentiment: BLUK at 79% against Stack AR's 32%. BLUK also leads on rating (4.8 vs 3.8) and ads (none vs shown). Stack AR's advantage is ratings volume (2.1K vs 157). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. BLUK sells 1 one-off in-app purchase and Stack AR sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
BLUK holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: Stack AR has 2.1K ratings behind it against 157, so its average is the more settled of the two. Written reviews point the same way: 79% of BLUK's written reviews are positive against 32% of Stack AR's.
BLUK ships an update every 2 weeks, Stack AR every 4 months. The most recent releases landed on September 21, 2026 and September 22, 2026 respectively.
