Regulate, Reflect, Connect. Here's what each one actually means.

Get it out
Vent, write the letter you'll never send, or let the words dissolve. Private writing never leaves your phone.
"You showed up.
That matters more
than you know."

Don't stay alone with it
Text someone in your life with words already written for you, sit quietly with a friend, or read real words from people who've been there.
"How are you now?"
After each tool: better, about the same, or worse. Better? Leave whenever you're ready. Same? Try a different kind of reset. Worse? Reach someone. O₂ remembers what helped, only on your phone.

Don't stay alone with it
Reaching out, made easier.
The hardest part is often the first message. O₂ helps with that, and with the moments you don't want to talk at all.
Reach someone
Pick what would help: just be with me, listen, or take my mind off it. Your message is written for you. Change anything, then send it from your own phone.
"Hey, something hard happened. Could you just listen for a bit? You don't have to fix anything."
Help me say it
Apologize, say you're not ready to talk yet, ask for help, or set a boundary. Fill in a few blanks and your words come together. No AI, nothing sent until you send it.
"Hey Sam, I'm sorry I snapped at you earlier. You don't have to answer right away."
Sit with me
Don't want to talk? Two quiet minutes with a calm, breathing presence. Invite a friend with a link and see "Patrick is here" when they join. No chat, just company.
Tap your glow to send them a soft pulse.
Real words from real people
Left here by someone who's been there.
Every letter is written by a real person and reviewed before anyone reads it.
"I know you are reading this tired. Maybe at the end of a shift, maybe in the middle of one. You showed up. That matters more than you know."
"What you do is hard. You deserve to be treated like a human being, and I am sorry every time that did not happen."
"Recovery was never about being perfect. It was always about refusing to quit."
Who's been here
Moms, nurses, dispatchers, athletes, students, teachers, first responders. Add yourself to the wall, no name needed, and see who else has been where you are.
Private by design
Nobody has to know you were here.
- No account, no download. Open it in your phone's browser and start.
- Private writing stays on your phone. It's never sent anywhere.
- You choose what to share. Anything you leave for others is reviewed first, with no names.
- Not a substitute for care. If you're in crisis, call or text 988, any time.

Questions
Good to know
Is O2 Rhythm related to oxygen equipment?
No. O2 Rhythm is a free mental wellness app for the minutes after a hard moment. It isn't a medical oxygen device and has no connection to oxygen concentrator brands. The O₂ stands for the breath you take to calm down.
Is it really free?
Yes. Anyone can open O₂ Rhythm on their phone and use every tool for free.
Do I need to download anything or sign up?
No. It opens in your phone's browser. There's no account, no email, and no password.
Can I put it on my phone like an app?
Yes. Open O₂ Rhythm on your phone and tap "Add O₂ to your home screen." On iPhone: in Safari, tap Share, then Add to Home Screen. On Android: tap the ⋮ menu, then Add to Home screen or Install app. It gets its own icon and opens in one tap.
If I invite a friend to sit with me, what do they see?
A short note that someone asked them to sit for two minutes, then the same calm screen you see. No chat, no messages, no names stored. They just show up, and you see that they're there.
Who can see what I write?
If you keep it private, nobody. It stays on your phone. If you choose to leave something for others, it's reviewed first and shared without your name.
Is this therapy?
No. O₂ Rhythm is for the minutes after a hard moment. It works alongside counseling, peer support, and crisis lines, not instead of them.
What if I'm in crisis?
Please reach out now. Call or text 988 (Suicide and Crisis Lifeline) or call 911 if you're in immediate danger.
Can my school, team, or workplace use it?
Yes. See organization access for QR codes and ready-made materials.
Keep it one tap away.
Add O₂ to your home screen so it's there the next time something happens. iPhone: Safari, Share, Add to Home Screen. Android: ⋮ menu, Add to Home screen.
