# HBN Smart vs GraviTrax Power

The clearest difference is rating: HBN Smart at 4.8 against GraviTrax Power's 3.7. HBN Smart also leads on ratings volume (3.2K vs 6) and iOS requirement (12.2 vs 15.0). GraviTrax Power's advantage is review sentiment (75% vs 51%). On price, update cadence, ads and in-app purchases there is nothing between them.

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

HBN Smart holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: HBN Smart has 3.2K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 51% of HBN Smart's written reviews are positive against 75% of GraviTrax Power's, so the app with the better star average is not the one people write more warmly about.

HBN Smart ships an update every 8 months, GraviTrax Power every 10 months. The most recent releases landed on October 27, 2026 and October 22, 2026 respectively.
