Coucou for Android

Your computer does the work, your Android phone keeps you in the loop when you step away.

Download Coucou for Android 0.3.0

A signed APK, free, no ads. By Rhytam Biswas (@Rhytam23).

Home: Mochi, the agent list, plan usage and a service

The lock screen: Approval needed, with only the tool and the program’s name

A notification from Mochi with Deny and Allow buttons

What you need

Computer: Coucou 0.4.0 or later on Windows or Linux (Windows, Linux). The Mac isn’t supported yet.
Phone: Android 11 or later.
Wi-Fi: the phone and the computer on the same network. No account to create.

Get it on your phone

Download Coucou-Android-0.3.0.apk from the release page on your phone and open it. Android asks once to allow installs from your browser or file manager.
On your computer: close any older Coucou, start 0.4.0 or later, then Settings → Android phone → turn on Phone link. If Windows asks about the firewall, allow Coucou on private networks.
Show pairing code, then scan it with the app (or paste the link).
Start a Claude Code session on the computer: it shows up on the phone within seconds.

You can check the download with sha256sum -c SHA256SUMS. Claude Code must be in a mode that asks for permission, or nothing is sent to the phone.

What you can do

Allow or Deny a permission from the notification or the app, even on a locked phone. A request wakes the screen (you can turn that off, and choose a standard, short or no vibration; the request itself always arrives); notifications show at most the tool and the program’s name, never the full command. Allow asks for your fingerprint or screen lock.
Answer Claude Code’s questions and chat through your computer’s own AI keys, when you turn them on in the computer’s settings.
See your agents at a glance: who is working, plan usage and your services.
Widgets for your home screen: Solo, List, Mochi Big, Status Pill, Waiting Alert, Usage Ring, Today, Mochi Mood, Your team (the agents you pick) and the Agents summary. They show your agents’ names and how they are doing, never a command or a file, and a request is always decided in the app.
Your history: an optional weekly recap on Home (counts only, switched on from your computer), search and export of your recent decisions, and a mute for one agent’s finished and failed notices. Requests and questions are never muted.
Quick actions: long-press the app icon for Chat, Recent decisions or Pair again, and share text from any app to your computer’s chat. A shared text only lands in the box; you decide whether to send it.
An island over other apps (optional), a quick-settings tile, and a notification that keeps the link alive.
Mochi, his outfits and his sounds, on your phone.
In your language: English, French, Spanish, Brazilian Portuguese, Simplified Chinese, Hindi, Bengali, Russian, Indonesian and Arabic (right to left), from the app’s settings or Android 13’s own language screen.
Light or dark: follow your phone or choose, and optionally use your phone’s own colours. Mochi looks the same in both.
Made for TalkBack and large text: agents, tabs, requests and every Widget are spoken in words, controls are at least 48 dp, and a “Reduce motion” choice stops Mochi’s idle animations.

Private by design

The phone talks straight to your computer on your Wi-Fi: TLS with a certificate pinned from the pairing code. The phone link is off by default and nothing listens until you turn it on.
A command too long to show in full can only be allowed on the computer. Each request expires after two minutes.
The pairing, chat and approval screens can’t be captured or recorded. No ads, no analytics, no tracking.
