What SmoothDroid focuses on
- Native macOS app for macOS 12 or newer.
- USB/MTP transfers with no cloud and no phone companion app.
- Side-by-side Mac and Android panes.
- Drag and drop, copy/paste, rename, delete, and folder creation.
- Conflict detection when macOS or another transfer app blocks the phone.
When OpenMTP may still be right
If you specifically want a free and open-source app, OpenMTP should be on your shortlist. SmoothDroid is for people who are comfortable paying once for a focused Mac utility with direct support and a notarized download.
When SmoothDroid makes sense
Choose SmoothDroid when you want a small commercial tool whose product promise is narrow and explicit: Android file transfer for Mac, locally over USB, without account setup or cloud storage.
