# MobiSquirt vs ECU Connect

The clearest difference is rating: ECU Connect at 4.0 against MobiSquirt's 2.3. ECU Connect also leads on update cadence (every 3 weeks vs every 41 months) and ratings volume (88 vs 3). MobiSquirt's advantage is iOS requirement (9.0 vs 15.0). On price, review sentiment, 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.

ECU Connect holds the better App Store score, 4.0 against 2.3. That said, the two scores are not equally well evidenced: ECU Connect has 88 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 67% of MobiSquirt's written reviews are positive against 62% of ECU Connect's, so the app with the better star average is not the one people write more warmly about.

MobiSquirt ships an update every 41 months, ECU Connect every 3 weeks. The most recent releases landed on October 23, 2026 and October 29, 2026 respectively.
