I'm writing this on a Thursday evening, which isn't my usual day. But I wanted to tell you something before you hear it anywhere else.

For the last eight months, I've been quietly building an app. It's called Clarus, and it's a place to track your mood, work through what's happening in your head using CBT tools, breathe properly, journal, and talk to an AI when you can't sleep at three in the morning. It's free. It's private. It's built in Ireland, in a spare room and coffee shops around Dublin.

The Monday Note — the letter you've been reading — is part of the same idea. I wanted to write something honest about mental health every week, and somewhere along the way I realised that people didn't just need something to read. They needed a place to practise. A space where they could check in with themselves, notice patterns, try something small, and know that someone understood why that matters.

So I built that. With a family member who records breathing exercises in her yoga studio. With people who've been exactly where you are — tired, sceptical, not quite ready to talk to anyone but needing to talk to someone.

The app isn't perfect. It doesn't pretend to be therapy. It's more like having someone you trust in your pocket who knows that sometimes you just need five minutes to breathe, or a space to write without anyone judging you, or a way to notice whether your mood is actually getting worse or whether you're just having a rough week. The Monday Note continues inside the app, by the way — still one idea a week, still yours to read free.

It launches today — Friday 24th April — on the App Store.

What I'm nervous about is the usual thing — whether it'll actually help. Whether I've built something that makes sense to you, or whether it'll sit there on the App Store with my name on it and do nothing. But mostly I'm just quietly excited. Because it's done. And it's yours if you want it.

Thank you for reading these letters. They matter.

This is for the ones we've lost along the way.
