Verdict
The clearest difference is review sentiment: GTRMax at 83% against Units's 45%. GTRMax also leads on in-app purchases (none vs 3) and update cadence (every 9 days vs every 5 weeks). Units's advantage is rating (4.9 vs 4.7) and ratings volume (261 vs 26). On price, ads 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. Units sells 3 in-app purchases, starting at $0.99 per month. GTRMax asks for nothing beyond the download.
Units holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Units has 261 ratings behind it against 26, so its average is the more settled of the two. Written reviews complicate that: 83% of GTRMax's written reviews are positive against 45% of Units's, so the app with the better star average is not the one people write more warmly about.
GTRMax ships an update every 9 days, Units every 5 weeks. The most recent releases landed on October 2, 2026 and October 11, 2026 respectively.
