harryhuynh.x@gmail.comFrequently asked
Does XMetric work offline?
Yes. All conversions and calculators run entirely on your device — no
internet connection is required.
Why does a value look different than I expect?
Results are rounded for display (up to 6 significant digits, switching to
scientific notation for very large or very small numbers). The underlying
calculation uses full precision.
How do I pin a conversion to Favorites?
Open any conversion and tap the star icon in the top-right corner. Pinned
favorites also appear in the home screen widget.
The home screen widget isn't showing my favorites.
Make sure you've pinned at least one favorite in the app, then long-press
the widget and choose “Edit Widget” to confirm it's linked to XMetric. If
it still doesn't update, removing and re-adding the widget usually fixes it.
I found an incorrect conversion factor.
