What is a streak?
Streak means 'in a row' - if you meditate for 3 days in a row you will have a streak of 3 days.
You can start your streak by listening to meditations. Every following day you listen to a meditation or program, it will be counted for your streak.
Please note that listening to music does not count as meditation time for your streak. The exception is listening to music using the Gong Timer.
