# ABG Expert vs Glasgow Coma Scale

The clearest difference is review sentiment: ABG Expert at 100% against Glasgow Coma Scale's 50%. ABG Expert also leads on ratings volume (9 vs 1) and update cadence (every 5 months vs every 11 months). Glasgow Coma Scale's advantage is rating (5.0 vs 4.8). 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.

Glasgow Coma Scale holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: ABG Expert has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of ABG Expert's written reviews are positive against 50% of Glasgow Coma Scale's, so the app with the better star average is not the one people write more warmly about.

ABG Expert ships an update every 5 months, Glasgow Coma Scale every 11 months. The most recent releases landed on October 20, 2026 and October 18, 2026 respectively.
