Pi Companion is an unofficial iOS companion app for the Pi coding agent (pi.dev) — browse your projects, read full chat history, and keep talking to your agents while away from your Mac. Start a task in your terminal, go for a walk, keep directing the agent from your phone, and come back to continue on the desktop — same session, no restarts. HOW IT WORKS A small open-source companion server runs on your Mac. It reads Pi's session files and drives Pi over its documented RPC protocol. The app connects directly to your Mac over your own network — no cloud, no accounts, no analytics. Use tools like Tailscale to reach your Mac from anywhere. FEATURES • Projects and workspaces: the folders you choose, grouped by git repo, with branches and live status • Full chat history: messages, thinking blocks, tool calls, and images • Send messages: continue any session from your phone; the terminal …
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 5 screenshots above are Pi Companion's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: Pi Companion runs a dark set with one background colour (#0C040C) carried across every screenshot — the listing reads as a single poster when the shots sit side by side in search results. The accent colour we picked up, #8C4C64, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
