Hey,

You signed up for MentaFlow updates a while back, and then heard nothing. That's on me. Short version: I kept building instead of publishing. The building part is done. This is the publishing part.

MentaFlow is open now. It's a set of browser brain-training games — about 60 of them — plus a focus-audio engine, built solo, by me.

The fastest way to see it is this: a reaction test you can play in about 10 seconds. No account, no email, nothing to install.

If reaction tests aren't your thing, there are a few other free tools that also need no signup:

• Memory test: https://www.mentaflow.app/tools/memory-test
• Breathing timer: https://www.mentaflow.app/tools/breathing-timer
• Binaural beats generator: https://www.mentaflow.app/tools/binaural-beats-generator

That's it. No countdown, no "spots remaining." If you try one and something breaks or annoys you, reply to this email — it goes straight to me, and right now I fix things the same week.

Dan Founder, MentaFlow
