Track by week, month, or see your entire year at a glance. INSIGHTS WITHOUT JUDGMENT See where you've been showing up the most. No percentages telling you that you failed—just a simple view of your effort, your way. MAKE IT YOURS Choose from 20 beautiful color themes. Track as many activities as you want. Log simple yes/no completions or measured quantities—your choice. WHY EMBER? - No goals to fail - No streaks to break - No guilt, ever - Just show up and watch your progress glow Small sparks make everlasting flames. --- Download Ember and start showing up for yourself.
