About this app
Stub is an iOS app that tracks everything with a date attached to it — warranties, return windows, utility bills, subscription invoices, credit card statements, medical bills, rent, insurance premiums, and anything else a household deals with on paper, in email, or as a PDF. Everything stays on-device unless you explicitly share it.

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.
Price tracking
Price intelligence
First snapshot captured. The trend line starts after the next crawler price observation.
