Syncbox: Couple App Android

Syncbox: Couple App

A private space for two. Write letters, share your days, keep them together.

Overview

Features & Capabilities

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.
