Right now Foyer runs on Mac and iPhone. An Android version is not in progress, and this page won't pretend otherwise. What the waitlist actually does: it counts you.
Send a one-line email and you're on the list. If an Android version ships, you get exactly one message. If it never ships, you get none. No newsletter, no follow-ups, and the address goes nowhere else.
It opens your mail app with the message pre-filled. Sending it is the whole signup.
Why the count matters
Foyer is built by one person. The audio engine is native Apple code today, so Android is a real rebuild, not a checkbox. Whether that rebuild is worth months of work depends on how many people are actually waiting; this list is how that gets measured. Every email genuinely moves the decision.
Meanwhile, the browser version of the idea

There is also a pomodoro timer that plays them while you work. If you have an iPhone or a Mac somewhere in your life, the full app is a one-time $9.99, no account, on both.

It sits on the list. If an Android version ships you get one message; if it never ships you get none. No newsletter, no sharing, and you can ask for removal any time by replying.
