Verdict
The clearest difference is review sentiment: Stack Overflow AR at 100% against Traumatica's 56%. Stack Overflow AR also leads on monetization model (free vs ad-supported) and iOS requirement (12.0 vs 16.0). Traumatica's advantage is rating (5.0 vs 4.0). On price, ratings volume, update cadence and ads 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. Neither carries in-app purchases, so what you see is what you pay.
Traumatica holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 1 and 1 respectively. Written reviews complicate that: 56% of Traumatica's written reviews are positive against 100% of Stack Overflow AR's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
