Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
