What counts as an active day?
The one measure behind hatching, growing up, and your WatchieBesti Family history.
The definition
An active day is any day your warmth bar moves: you moved enough, according to your Health data, to make a difference. It's not tied to a single workout: any movement that nudges the bar counts.
Where it shows up
The same active day counts in four different places across the app:
- Hatching Speed: an active day is what cracks and hatches your egg. Fast can crack and hatch in as little as two active days; Patient spreads them further apart.
- Evolution & Growing Up: active days feed your besti's progress bar toward the next of four life stages, alongside feeding Bursts directly.
- WatchieBesti Family: tap any graduated besti and their history shows exactly how many active days you shared together.
- Achievements: the Streak chip tracks your longest run of active days in a row.
Active days vs. Bursts
An active day is a simple yes/no threshold for the day: did the warmth bar move. Bursts are a separate, bigger reward earned from a specific tracked workout, a burst of everyday activity, or winning a Brain Boost game. Each one you feed gives an instant (capped) push to growth, on top of whatever active days already do.
