PulseDuo is a quiet little line between two people. No texts. No emojis. No feeds. Just a tap your partner feels on their iPhone or Apple Watch — a private language you build together. • Create up to five custom patterns, each with its own name, color and sequence of taps. • Send one with a single tap — from the app, a widget, or your watch face. • Feel theirs arrive, wherever you are. • Keep a private journal of every pulse, with a daily streak to keep the habit alive. Everything lives in your own iCloud. No accounts, no servers, no tracking, no ads — your touches stay between the two of you. Pair once with a 6-character code, and you're connected.
