ER NAV brings this tech into EMS by allowing EMT's and Medics to quickly find the nearest hospital and route direct to the ambulance bay using your preferred navigation app. Ambulance Bay Navigation Go directly to the correct EMS entrance, not the hospital’s main lobby.

No digging through outdated documents or memory. Use Your Preferred Apps Tap once to open your route in Apple Maps, Google Maps, or Waze. ER NAV works with the navigation app you're already used to. Ambulance Bay Images See user-submitted images of the ambulance bay so you know what you're looking for.

Verdict
The clearest difference is rating: ER NAV at 4.7 against Huly's 3.4. Huly's advantage is in-app purchases (none vs 1) and update cadence (fortnightly vs every 3 months). On price, ratings volume, 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. ER NAV sells 1 in-app purchase, starting at $2.99 per month. Huly asks for nothing beyond the download.
ER NAV holds the better App Store score, 4.7 against 3.4. Both are backed by a comparable volume of ratings — 5 and 14 respectively. Written reviews complicate that: 100% of Huly's written reviews are positive against 86% of ER NAV's, so the app with the better star average is not the one people write more warmly about.
Huly ships an update fortnightly, ER NAV every 3 months. The most recent releases landed on September 13, 2026 and September 20, 2026 respectively.
