Send silent one-tap hellos to people you love
Psst is a free iPhone app for sending a quiet “thinking of you” signal with one tap. Connected friends receive a whisper and can reply directly, including from a notification.
Invites are mutual, with no feed, strangers, contact uploads, location sharing, or spam. Psst+ adds personal extras such as custom colors, app icons, and whisper sounds.
