You spend hours a day on calls. Almost nobody tells you how you sounded.
Did you talk over people? Rush when it got tense?
Most tools that could tell you record everyone, upload it to the cloud and charge monthly.
Halen runs on your Mac. Do the 30‑second voice check and it ignores every voice but yours. It turns the sound into a few numbers and throws the audio away.
No bot in the call. No audio saved. No account.
After each call you get one thing to try next time. You say how it went. After six rated calls it shows you which habits match your good ones.
Like a fitness ring, but for how you talk.
