Latest release
What’s New
When you add an event after picking a day on the calendar, that day is now filled in from the start. This makes it easier to enter past records one after another. Adding from the timeline, or with today selected, works exactly as before.
Audience growth
Ratings growth
Baseline captured. Growth appears after the crawler observes a changed rating count.
Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
