Zynk vs Blip

Blip nails direct transfer: any size, resumable, end-to-end encrypted. Zynk matches that and adds a menu-bar tray you drop contacts onto, conversations that keep the history, and a CLI Blip doesn't have.

What we noted

Blip is a focused direct-transfer app with any-size sending, resumable transfers, and end-to-end encryption. It does the send action well.
If all you want is to fire a big file across and forget it, Blip's one job keeps it simple. Zynk's extra surface pays off only when you want more than the send itself.
