A driver's car ledger that opens like a notebook, a summary beside the details
Does 車本本 CarNote work on iPhone Duo?
Yes. 車本本 CarNote's App Store page says it supports iPhone Duo, so the update is out. FoldHunt's editor hasn't seen it running yet.
- App Store confirmedHSIU FAN WANG, the developer, in the App Store release notes for version 1.0.2 (released October 11, 2026): open, each chapter has two facing pages, and while you drive the gauges sit on the left and the live rankings on the right. In an email to FoldHunt on October 17, 2026, the developer described the layouts in more detail and said they were captured in the iPhone Duo simulator with the same 1.0.2 build that's on the App Store.

About 車本本 CarNote
