What can I spend coins on?
Boosts, streak items and profile cosmetics.
Updated 8 October 2026
1. Choose an item
Shop lists each item's price before you buy. Coins can buy timed Double XP boosts, streak items, avatar frames, profile titles and name colours. Permanent cosmetics remain owned; choose an owned cosmetic to equip it. Only one of each cosmetic type is shown at a time.
2. Check the duration
Timed boosts expire at the time shown in Shop. Purchased streak points last until the streak breaks and do not create past study days. Shop items do not unlock additional AI marking. Name colours have a shine effect, which is disabled when reduced motion is requested.
