A few minutes a day to breathe, take stock and organize your days.
Méthode Sérénité & Vitalité is a web app that brings together guided breathing exercises, a daily relaxation check-in, morning and evening routines and practical tools. Everything runs in your browser, with no installation, at your own pace.
Sérénité & Vitalité
Easy to open, pleasant to use, easy to keep up throughout the day
Many wellness tools require an account, an installation and a good deal of discipline. Here, you open a link, choose an exercise, and that's it. The interface stays calm, the sessions stay short, and you set the pace.
Short sessions
A breathing exercise lasts between 2 and 5 minutes. The daily check-in takes just a few seconds to fill in.
Nothing to install
The app runs in the browser of your phone, tablet or computer. No download.
A calm interface
Soft colors, a single action per screen, no ads and no intrusive notifications.
At your own pace
No imposed schedule and no counter. You move forward whenever you wish; the tracking grid simply records your consistency.
What's in the app
Five complementary tools, brought together in a single personal space and available as soon as the dashboard opens.
Animated guided breathing
A circle that expands and contracts to guide each inhale and exhale. Three rhythms to choose from depending on the moment: balanced, slow or box. You pick the duration; the animation does the rest.
Daily relaxation check-in
Each day, move a slider to record your perceived level of relaxation. A trend curve takes shape over the days, to look at whenever you wish.
Morning and evening routines
Two short checklists: a few small actions to start the day, a few to close it. You tick them off as the day goes on; the lists reset the next day.
Tracking grid
A visual grid marks the days you did a breathing session, filled in your check-in or completed a routine. One glance is enough to see your consistency over the past few weeks.
Practical tools
Clear guides you can consult at any time in the app: preparing your day, taking a two-minute break, reviewing the week at its end.
Personal area & dashboard
Your area opens directly on the dashboard. Your progress is saved automatically in your personal space. App updates are included.
A clear dashboard, designed for phone and computer alike
Everything is visible on a single screen: breathing, today's check-in, your routines and your tracking grid.
