About Fuel Log: Mileage Tracker
Fuel Log keeps your fill-ups, maintenance and road trips together, works out fuel economy and maps your stops. The October update adds iPhone Duo support but doesn’t describe how the app looks closed, half-folded or open.
The same release notes say sharing through an App Clip is switched off for now, because of an upload problem.
