Kor grows with your total number of full days. A full day is a day where you finish every habit you planned. They don't have to be in a row: miss a day and your total stays where it was.
Levels
Each level takes a certain number of full days:
- Lv 2: 2 · Lv 3: 4 · Lv 4: 7 · Lv 5: 10 · Lv 6: 14 · Lv 7: 21 · Lv 8: 28 · Lv 9: 35 · Lv 10: 42 full days.
- After Lv 10, every level takes 8 more full days (Lv 25 is at 162). There's no top level.
Every level up earns +20 sparks and opens the Level up! screen.
Three stages
- Kor Cub (Lv 1): with you from day one. Can wear hats and neck items.
- Young Kor (Lv 10, 42 full days): glasses, back items and flame colors unlock, and Kor gets a bushier tail.
- Master Kor (Lv 25, 162 full days): the Golden flame lands in your wardrobe and a Kor portrait in your den.
When Kor reaches a new stage, you'll see Kor grew up! Tap Share on the level screen to send a picture of the new look.
Checking your progress
The level card in the Kor tab shows your level, the full days you've done at this level and how many are left until the next stage (for example, "12 full days to Young Kor"). Once Kor is a Master, it says Kor is fully grown.
If you undo a check-off today, the progress from that day goes back too. Past days are locked in, though: archiving or deleting a habit never makes Kor smaller.
