Does Fuel Consumption – DriveDex work on iPhone Duo?
Yes, since version 2.5.0 on October 20, 2026, and seen in a simulator recording: open, your vehicles sit beside the selected one's stats, and logs open in windows of their own.
- Simulator verifiedFlorian Seida, the developer, in a submission to FoldHunt on October 20, 2026, with a recording of the app in the iPhone Duo simulator in a post on X. The release notes for version 2.5.0 (released October 20, 2026) say DriveDex makes better use of the screen on iPhone Duo and iPad, and that vehicles, statistics and logs can now open in separate windows.
Adapted for the fold
- Open · Inner display
Vehicles beside their stats
Open, all your vehicles sit in a column on the left, and the one you picked fills the right with its current trip, mileage, consumption, costs and parts.
- Split View · Two apps
A window each
Statistics, trips and logs can open in windows of their own, so a trip can sit beside its mileage chart, or a DriveDex window beside another app.
- Closed · Outer display
One vehicle at a time on the cover
Closed, you swipe between your vehicles at the top of the screen, with the selected one's highlights below.
About Fuel Consumption – DriveDex
DriveDex keeps track of the maintenance, costs and use of all your vehicles, from cars and motorcycles to boats and bicycles. Log refuels to see their real fuel consumption, get reminders before a service is due, record trips with their own statistics, and keep every expense and repair in one history. Usage can be counted in miles, kilometers or operating hours, and there are widgets, Shortcuts, Siri commands and iCloud sync.
Version 2.5.0, out on October 20, 2026, is Florian Seida’s first update for the iPhone Duo. Open, the app shows two columns: your vehicles on the left and the selected one’s stats on the right. Vehicles, statistics and logs can also open in windows of their own, on the Duo and on iPad.
