Key takeaways
- The useful developer watch apps are notifications, 2FA, status tiles and timers; terminals are a last resort.
- The empty category was agent supervision: approvals, prompts and replies fit a watch perfectly.
- PeakWatch fills it with a relay you run and a standalone Wear OS client.
Developers buy smartwatches for the same reasons as everyone else and then discover the app store has almost nothing for the work they actually do. Here is what exists, what is worth installing, and the category that was empty.
What works today
- Notifications, filtered hard. The single most useful thing a watch does for a developer is deliver the three notifications that matter (CI failed, pager, a direct message) without the phone. Spend the time on the filters.
- Two-factor codes. Authenticator apps with Wear OS tiles turn a phone hunt into a glance.
- CI and uptime status. Several dashboard apps put build and incident state on a tile; most are thin wrappers, all of them beat unlocking the phone.
- Timers, voice notes and reminders. The unglamorous productivity layer, and it is good.
- SSH and terminal clients. They exist. Typing a command on a 1.5-inch screen is an emergency measure, not a workflow.
What was missing
Anything to do with the agents that now do a large share of the work. A coding agent runs for minutes, stops to ask for permission, waits for a prompt, and finishes. Every one of those moments is a natural watch interaction: read a sentence, tap, dictate a line. No watch app did it, because a watch cannot run the agent and there was no protocol for driving someone else's session.
Filling it
PeakWatch pairs the watch with a small relay on your machine that owns the sessions through the Claude Agent SDK. The watch lists sessions ranked by what needs you, approves or denies tool requests with the arguments in view, takes prompts by voice, streams replies, summarises a session in one screen and shows your plan usage. It also mirrors sessions you started in a terminal. Standalone over WiFi or LTE; phone optional.
What to want next
Diff previews on the wrist for small changes. Voice-driven code review for pull requests. A richer set of quick replies learned from your own habits. And the same supervision surface for agents beyond Claude Code.
PeakWatch is built for this
Your coding agent, on your wrist. Coming soon, free during the beta.

Which watch is best for this?
Can I run the relay on a laptop that sleeps?
Does PeakWatch work with the phone off?
