# TruMonitor vs ABG interpreter

The clearest difference is review sentiment: ABG interpreter at 100% against TruMonitor's 34%. ABG interpreter also leads on monetization model (free vs free with in-app purchases) and iOS requirement (13.0 vs 15). TruMonitor's advantage is rating (3.7 vs 3.0) and update cadence (monthly vs every 19 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

TruMonitor holds the better App Store score, 3.7 against 3.0. That said, the two scores are not equally well evidenced: TruMonitor has 49 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 34% of TruMonitor's written reviews are positive against 100% of ABG interpreter's, so the app with the better star average is not the one people write more warmly about.

TruMonitor ships an update monthly, ABG interpreter every 19 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
