Verdict

The call

The clearest difference is rating: ER NAV at 4.8 against TigerConnect EMS's 4.0. TigerConnect EMS's advantage is in-app purchases (none vs 1) and update cadence (every 2 weeks vs every 3 months). On price, ratings volume, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

ER NAV holds the better App Store score, 4.8 against 4.0. Both are backed by a comparable volume of ratings — 20 and 16 respectively. Written reviews complicate that: 100% of TigerConnect EMS'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.

UpkeepUpdate frequency

TigerConnect EMS ships an update every 2 weeks, ER NAV every 3 months. The most recent releases landed on November 2, 2026 and October 30, 2026 respectively.
