# VCEMS Mobile vs ER NAV

The clearest difference is in-app purchases: VCEMS Mobile at none against ER NAV's 1. VCEMS Mobile also leads on rating (5.0 vs 4.7) and iOS requirement (15.0 vs 17.5). ER NAV's advantage is update cadence (every 3 months vs every 15 months) and ratings volume (14 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. ER NAV sells 1 in-app purchase, starting at $2.99 per month. VCEMS Mobile asks for nothing beyond the download.

VCEMS Mobile holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: ER NAV has 14 ratings behind it against 1, so its average is the more settled of the two.

VCEMS Mobile ships an update every 15 months, ER NAV every 3 months. The most recent releases landed on September 15, 2026 and September 20, 2026 respectively.
