MobiSquirt allows you to connect your iOS device to a MegaSquirt ECU, view realtime data from your car's engine control system and log that data for later analysis using available tools such as MegaLogViewer. MobiSquirt will eventually support all versions of the MegaSquirt firmware but initial versions of the app will concentrate on compatibility with MegaSquirt 1, MegaSquirt 1 - Extra, MegaSquirt 2 and MegaSquirt 2-Extra. It is also anticipated that support for MegaJolt will be added. Version 1.2 of the App has been tested against most versions of the MS1-Extra and MS2-Extra firmware. Other firmware versions have partial or no support in this version. Use of this app will require provision of a WiFi or Bluetooth connection to your MegaSquirt ECU. Details of suitable options for this are available on the app web site - https://mobisquirt.org/ and in the user manual available at https://mobisquirt.org/user-manual/

Verdict
The clearest difference is rating: OBD2 Car Scanner at 4.6 against MobiSquirt's 3.0. OBD2 Car Scanner also leads on update cadence (every 5 weeks vs every 41 months) and ratings volume (5K vs 4). MobiSquirt's advantage is in-app purchases (none vs 3) and review sentiment (67% vs 55%). On price, ads and device support there is nothing between them.

Both are free to download. OBD2 Car Scanner sells 3 one-off in-app purchases. MobiSquirt asks for nothing beyond the download.
OBD2 Car Scanner holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: OBD2 Car Scanner has 5K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 67% of MobiSquirt's written reviews are positive against 55% of OBD2 Car Scanner'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, OBD2 Car Scanner every 5 weeks. The most recent releases landed on July 20, 2026 and September 23, 2026 respectively.
