[Jiji]

TL;DR: TestFlight Invite

Build 2026.03.15 Update

ATTENTION 2026.03.3 USERS:
Make a backup of your trips/charges before installing this build
- Settings.Database, Backup
- Install new build
- Clear the database, Settings.Database, Clear Database
- Restore from your backup

If you can’t log a trip or charge, make sure background operation is enabled in Settings.Bluetooth (a red symbol in the Bluetooth button means you are disabled).

What's New
Key updates are robustness and user features:
- 2025 Mustang Mach-E support (OBDLink MX+ required)
- create/edit charges using the Ford app Charge History (no OBDLink required)
- more robust design works without network connection
- Live Activities are properly supported (iOS does not allow Live Activities from background app)

Trips
- destination updates every 10 seconds with reverse geocoded address
- trips start and end gracefully even if there is no network connection
- view high voltage battery history

Charges
- charges start and end gracefully even if there is no network connection
- manually create a new charge
- edit a charge detail
- view high voltage battery history
- graph coupler temperature when charging
- State of Charge is now displayed on the charge power chart

Settings
- Bluetooth settings allows you to enable and disable operation and pair to a specific adapter
- fixed bug with Locations count shown as 0
- manually add new vehicles in the Vehicle settings (for those manually logging charges)

What is Pankuzu?
Pankuzu, which is Japanese for breadcrumbs, is an iOS application that records your trips and charges and dives into the individual details or aggregates you EV trips and charges to enlighten your Mustang Mach-E or F-150 ownership. Why Pankuzu? Every name I tried was rejected by Apple so I had tothink out-of-the-box to get this into TestFlight for your personal enjoyment.

Testing
As of this initial post, Pankuzu is untested, if you have a problem you can submit a screenshot or crash report using TestFlight. Once the source code is posted on GitHub, there will be a Issues and Discussion sections for problem reports and comments.

Disclaimer
Pankuzu is provided "as is" for entertainment purposes only and is not intended for, nor fit for, any specific purpose. The are no warranties, express or implied, regarding accuracy, reliability, or suitability. Use of this app is entirely at your own risk. There is a lot going on under the hood with Bluetooth, Swift, SwiftUI, SQLIte, and more and this is just another of my winter projects to keep the brain exercised in my advanced old age.

Specifically, do not go out and buy an OBDLink MX+ unless you see some independent reviews from others that already have an MX+ so aren't making a financial investment - caveat emptor.

Requirements
iPhone:
I have only used it on iOS26 and an iPone 17 Pro but should work on other iPhones or iPads

OBDlink MX+:
An OBDLink MX+ scan tool is required to record trips and charges but anyone can try out the user interface as the Database Seeding section in Settings lets you add trips and charges so

Privacy
No ads, no trackers, nothing bad.
All data collected is stored on your device and in your iCloud account and is not shared with anyone.
Location Always permission is required as Pankuzu runs in the background logging your position to create the trip route map. Location is only collected for the duration of a trip or at the start of a charge to display your location on a map.

Recording a trip
Happens automatically, as you approach your vehicle your phone will connect with the OBDLink <X+ scan tool and when you shift out of Park the trip will start recording. When the gear selector is returned to Park the trip ends. As I am a bit paranoid about this, there are optional notifications when the scan tool connects and disconnects and when a trip is started.

At least this is now it is supposed to work.

Trips
Let's look at your trips. The Trips tab shows your recent trips in a convenient or custom format. On the left are the trips taken today in all vehicles in the household or fleet. We can drill into the trip details (second from the left) and see the vehicle used, origin and destination, weather conditions along with the most useful vehicle details. The Route button will display the trip path on a map, scroll and zoom for pertinent details along the way. And the Elevation button adds useful insight into the ups and downs of the journey, 2.5mi/kWh as it was mostly downhill.

But wait, there is more to discover as map points of interest and weather data are integrated into the trip data. Tapping on the 'From' or 'To' field you find full address information plus the ability to select from nearby points of interest, Pankuzu will select the nearest but you can change it to your actual destination (left side). Or Tapp on the weather conditions and see a detailed summary of the weather along the route, looks like a stiff headwind on this trip.

Enough for now, I'll add the Charges at an another time, to be continued.

Thought this sounded familiar. You should mention that this is the outcome of your previous post that introduced the concept and many of us were looking forward to.

Really cool. I’m going to try this on the drive to work today.

 

[TenaciousG77]

Very cool concept. I guess I *need* the OBD tool now, you know, for testing purposes.

As the first guinea pig I hope it works that easily. I also hope you didn’t stop at the TL;DR and have the scan tool.

If you do I would love your feedback.

No scan tool required until you want to log your own trips.

In the meantime under Settings, Database Seeding, you can canned trips and charges and explore the Trips and Charges tabs.

Thank you! Downloading now!

Does it only work with OBDLink MX+??
I have another brand and can’t get it to connect.

 

[Sirkillz]

I’d like to point out using an app in TestFlight can be risky if you don’t know or trust the developer

 

[SFsparkie]

Thank you. Downloaded. OBD link arriving this evening. Looking forward to Friday’s drive round trip Oakland to Santa Cruz, Sunny (well warm rain) CA.

 

[Lightning Rod]

Thank you. Downloaded. OBD link arriving this evening.

Mine will be here today also. I've been putting this purchase off for several years now.

 

[Maxx]

Mighty cool. I love the elevation function. It would look really good on android ;(

 

[SFsparkie]

Mine will be here today also. I've been putting this purchase off for several years now.

I was thinking the OBDLinkMX+ may sell out. I’ve been using the Veepeak for car scanner. Hoping the upgrade to MX+ and PANKUZU is beneficial.

Very cool concept. I guess I *need* the OBD tool now, you know, for testing purposes.

No, try it out, except the recording aspects, and let someone else confirms it works. As I am the only one that has used this let others that already have an OBDLink MX+ and help iron out the kinks in 6he onboarding process.

Big mistake putting the TestFlight link at the top instead of making you read to the end.

edited: fixed testflight typo

I read the whole post. I was just hoping to be able to connect with the one I have as well
