## What is 4?

Slow down in 80 seconds.

4-7-8 is a simple breathing rhythm: breathe in for 4 seconds, hold for 7, breathe out for 8. This app guides you through it with a calm, glowing line. Just follow the dot.

FOLLOW THE LINE
The line rises as you breathe in, stays level while you hold and falls as you breathe out. A large countdown, soft bells and gentle vibrations tell you when to switch, so you can even close your eyes.

DEEPLY RELAXING BOOST
Add a soft binaural beat in the theta range (5 Hz) underneath your breathing. Put on headphones, set the volume you like, or turn it off.

BUILD THE HABIT
• Choose 3, 4 or 5 sessions a day
• Commit to 30, 60 or 90 days
• Set a time for each session and get a gentle reminder
• Every finished session gets a check mark

YOUR PROGRESS AT A GLANCE
Add the widget to your Home Screen or Lock Screen to see how many days are left and which of today's sessions are done.

SIMPLE AND PRIVATE
• One session is 4 rounds, about 80 seconds
• No account, no ads, no tracking
• Everything stays on your iPhone

Feeling a little lightheaded is common when you start. If it happens, stop and breathe normally. This app is a relaxation exercise and is not a medical treatment.
