Trip and charge logging iPhone app for the Lightning

[Jiji]

I few winters back I wrote a pair of iPhone apps to log trips and charges and while they worked they had limitations. My 2025-2026 winter project has been to update these apps to a single app that does it all and have none of the problems.

Feature	Old	New
Applications	2	1 (iOS, iPadOS)
Supported vehicles	Mustang Mach-E	Mustang Mach-E, F-150 Lightning
Internet connection required	Yes	No (only for optional weather data)
Database	Cloud, user-hosted and managed	On device
Trip recording	Manually start in app	Automatic in background
Charge recording	Manually start in app	Automatic in background
Apple Weather integration	No	Yes
Background operation	No	Yes
Privacy	Yes	Yes, location data is only collected during trips and is not shared.
Requirements	OBDLink MX+	iOS26, OBDLink MX+

I made a short video of the Trips feature, sucks but will do for now.

Probably a few weeks out of making it available via TestFlight for those with an OBDLick MX+.

Funnily enough I've been wanting to write the same thing

Lol, I bet

Can you collaborate with an Android DEV to bring this to our world?

Ooh, sounds cool! I’ll TestFlight beta for you.

Nice! Is the trip gathering statistics by simply driving to/from location, or setting navigation to the destinations (example of UPS store in the video) ?

Great! Let us know when it is available!

I know nothing about Android development but I will make the GitHub repo public once it is in TestFlight.

What you are dealing with is a SwiftUI app written in Swift with a few third-party packages that support using SQLite as the underlying database.

That's awesome, note I have zero DEV skills, but I think there are a few forum members who do, hope they read this thread.

Does the OBDLink MX+ work with ABRP? It doesn’t appear so but I couldn’t find a direct answer.

It does for me. Not sure how this relates to app development though.

Just curious, if you hadn't intended to go cross platform, why didn't you use CoreData or SwiftData? When developing, did you test on a bench or did you have to do it from the truck? Great job, looks fantastic!

Sorry. I was asking because I’m looking at getting a dongle for ABRP. Wanted to make sure I would only have to get one dongle that would work with ABRP as well as this logging app.

Thanks!

Wow, this could chew up a lot bandwidth but in a nutshell SwiftData uses classes and can only be used in views, I went with this as it uses structs and can be used anywhere (no views when a trip is recorded with the app in the background).

Plus it supports CloudKit so you can run the app on multiple devices and they are always in sync. i wont won’t be happy until I can implement CloudKit sharing, since my goal is to record both vehicles which are logged into different iCloud accounts are viewable on a single device.

As for testing I have to test on phone (no BT in the simulators) but there is debug code to simulate the vehicle connection to simulate the CAN bus commands that create trips and charges so I just have a 12V supply to power the scan tool at my desk.
