What Premium unlocks
| Every guided pattern | Box breathing, 4-7-8, coherent, alternate nostril, physiological sigh and the rest. |
| Custom pattern builder | Set your own inhale, hold, exhale and hold, and save it. |
| Session history | See what you actually practised instead of guessing. |
| No ads, no interruptions | A breathing app that interrupts you is a contradiction. |
| Offline use | Works on a plane, in a basement, anywhere you need it. |
Which one should you pick
If you are going to use it past four months, lifetime is cheaper — that is the whole calculation. Monthly exists so you can stop whenever you like without having spent much.
Free either way
You do not need Premium to breathe better today. Start with the guided breathing exercises, the box breathing walkthrough, or print the one-page breathing card. All free.
Frequently asked questions
How much does RhythmRx Premium cost?
Premium is 4 dollars 99 a month, or 19 dollars 99 once for lifetime access. The lifetime option pays for itself in about four months.
Is there a free version?
Yes. The core guided breathing exercises are free and stay free, and every guide on this site is free to read.
Can I cancel the monthly plan?
Yes, any time, from the billing portal. Cancelling stops the next charge and you keep access until the period ends.
What is the difference between monthly and lifetime?
Nothing in features. Monthly is 4 dollars 99 and recurring; lifetime is 19 dollars 99 paid once with no renewal ever.
Is RhythmRx medical treatment?
No. RhythmRx is a wellness practice app, not medical advice or treatment. If you have a heart or lung condition, or you feel faint during a breathing exercise, stop and speak to a doctor.
