Store listing

Full description
Some things are too long for a messaging app. And what you said yesterday gets buried under everything since. Syncbox is a private space for two. The letters you write each other, your everyday conversations, and the photos you take together — all in one place. ■ Three kinds of letters • Weekly letter — Look back on the week and write it down. Add that week's photos and a song, and map how each day felt. • Q&A letter — Pick a question and send it, and your partner writes the answer. The things you don't usually get around to asking. • Piece letter — Short, whenever. Send the thought that just crossed your mind. You can reply to a letter, or highlight a single line and leave a comment on it. ■ Just your conversations Send photos, videos and voice messages. Turn on disappearing messages whenever you want. Pick out a stretch of conversation worth keeping and save it. Find older messages by date or by word. ■ A shared feed Post photos or video links and build a timeline only the two of you see. React, and keep the conversation going in the comments. ■ Saved A line from a letter that stayed with you. A conversation you want to read again. A photo you took together. Everything you save is collected in one place, and searchable. ■ Because it's only for two • You connect with one person you invite. No followers, no suggestions, no strangers. • Turn on app lock and open it with a passcode or your fingerprint. • Letters and messages are stored encrypted. • You can delete your account and your records at any time. What the two of you said to each other scatters faster than you'd think. Keep it in Syncbox.
