Brands that installed a loyalty app

Three example rows · a real strip is built from Sonar’s storefront observations

Illustration with example data. A real list names brands observed installing the app, each with Sonar’s most recent check of that storefront.

Five jobs, one graph

Find, qualify, watch, understand, act.

Where the product has public records, the card shows them live, with the same dates and evidence labels you get after signing up. Where it doesn’t, the card shows an example and says so.

The data layer

Built on transparent data

Every feature above sits on the same evidence-labeled catalog of apps, brands, developers, and experts.

Public signals only

Everything is built from public App Store listings, storefronts, and ecosystem data. No private merchant or partner data, ever.

Accurate detections

When we detect an app on a store, it’s there — a detected install is a confirmed install observed on the storefront, and coverage grows every day.

Freshness you can see

Every brand and app page shows when Sonar last checked it, and each feature page’s proof object carries the same dates, so you always know how current a signal is.
