Duolingo 8 Day Streak Animation

The animation begins with a dim flame and the number seven. A bright yellow sunburst spins and scales up rapidly, exploding into a vibrant orange flame. Simultaneously, the number seven rolls upward to reveal an eight, accompanied by floating spark particles. A weekly calendar then slides up from the bottom, with the current day's progress bar filling up with a smooth orange slider animation. Finally, a motivational text card and a primary action button stagger into view from the bottom, completing the celebratory streak milestone.
