# Pumpout Nav vs Cortex Onboard

The clearest difference is rating: Pumpout Nav at 4.5 against Cortex Onboard's 3.8. Pumpout Nav also leads on ratings volume (117 vs 12). Cortex Onboard's advantage is review sentiment (56% vs 38%) and update cadence (every 2 months vs every 4 months). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Pumpout Nav holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: Pumpout Nav has 117 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 38% of Pumpout Nav's written reviews are positive against 56% of Cortex Onboard's, so the app with the better star average is not the one people write more warmly about.

Pumpout Nav ships an update every 4 months, Cortex Onboard every 2 months. The most recent releases landed on September 18, 2026 and June 7, 2026 respectively.
