SyncEar Desktop (beta) for Windows 10 and up.

Double-click SyncEar.exe to open.
No Java install needed (a Java runtime is bundled in the jre folder).

If Windows SmartScreen shows a warning (the app is not code-signed yet),
click "More info" then "Run anyway".

If SyncEar.exe will not start on your PC, run SyncEar.bat instead
(same app, batch launcher).
