A few things to know
Is Rest free?
Yes. The 12 background sounds and breathing guidance are free. The app also offers optional AI reading subscriptions; you do not need one for Rest.
Which courses and languages are available?
Six courses include natural breath awareness, 4-in/6-out, equal breathing, belly breathing, a gently longer exhale and a bounded 4–7–8 course. There are three voices in each of seven languages: Korean, English, Japanese, Simplified and Traditional Chinese, Thai and Vietnamese.
Do I need to match every count?
No. Stop guidance if you feel uncomfortable or dizzy, and breathe normally. The 4–7–8 course is limited to three minutes and four cycles. Rest is for relaxation, not for diagnosing or treating sleep conditions.
Do I have to use Saju or sign up?
No. Rest works without an account or birth details. You can explore the journal and daily stories separately whenever you like.
