# ECU Connect vs Nextbase

The clearest difference is rating: Nextbase at 4.7 against ECU Connect's 4.0. Nextbase also leads on ratings volume (515 vs 88). ECU Connect's advantage is review sentiment (62% vs 24%) and monetization model (free vs free with in-app purchases). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Nextbase holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Nextbase has 515 ratings behind it against 88, so its average is the more settled of the two. Written reviews complicate that: 62% of ECU Connect's written reviews are positive against 24% of Nextbase's, so the app with the better star average is not the one people write more warmly about.

ECU Connect ships an update every 3 weeks, Nextbase every 4 weeks. The most recent releases landed on September 26, 2026 and September 28, 2026 respectively.
