Key signals
What this cohort is telling us.
Store declarations, controlled coverage outcomes, and measured routes stay separate. Every chart is calculated from this observed 50-app snapshot.
Store declarations
Monetization is the norm
46% of the cohort declares ads and 46% declares in-app purchases in its Play listing.
46%declare ads

These are publisher declarations from Google Play, not independently observed ad impressions or transactions.
Controlled workflow
Coverage has a visible outcome
28 apps completed the zero-interaction coverage workflow; 13 ended at an explicit safety or availability boundary.

A terminal boundary is a recorded outcome, not a failed app and not evidence of monetization behavior.
Cohort distribution
Ratings cluster high
The median listed rating is 4.47 across 50 apps with a rating in this snapshot.
Ratings are current store metadata; Observer does not infer app quality from them.

How the evidence works
Store facts and device observations stay separate.
Observer records an app version on a defined store, market, device, journey, and point in time. Missing or blocked evidence remains visible instead of being filled in by inference.
Store metadata
Rank, developer, category, installs, rating, version, minimum Android, and store declarations captured with timestamps.
Coverage proof
Policy-correct install or inventory outcomes, provenance, cleanup, and zero-interaction handling; not a claim that a route or ad was observed.
Runtime routes
Controlled journeys with repeat counts, device version, captured evidence, and explicit complete or partial status.
SDK & network signals
Static package markers and privacy-minimized hosts. Neither is treated as proof of SDK activity, bidding, or an impression.
App discovery FAQ
What Observer can tell you
What is App Supply Observer?
App Supply Observer is a mobile app discovery and supply-intelligence tool. It combines timestamped app-store facts with separately labeled device, SDK, network, journey, and ad-surface evidence.
What can I search in the app catalog?
You can search apps by title, developer, Android package name, category, observed Google Play rank, install range, and available evidence state.
How current are the app rankings and versions?
Every ranking, store profile, version, and device observation carries its own capture time. Rankings are snapshots and may change by time, market, device, and Google Play surface.
Does an SDK signal prove that an SDK was active?
No. Static SDK signals are bundled-code markers. They do not by themselves prove initialization, auction participation, an ad request, or an impression.
Does Observer bypass certificate pinning or click ads?
No. Observer does not bypass TLS certificate pinning, patch apps, root devices, or click advertisements. Unavailable evidence stays labeled unavailable instead of being inferred.
Can I buy App Supply Observer data?
Yes. Clarion currently offers a bounded Android evidence pilot with sanitized JSON and CSV delivery, version-bound app profiles, static SDK inventory, reviewed routes, and qualified placement metrics where available. The public catalog is a preview; commercial cohorts and refreshes are available by request.
Does the commercial product cover both Android and iOS?
Qualified commercial measurement is Android-only today. The iOS observer foundation remains internal and is not represented as a sellable measurement lane until physical-device runs satisfy the same evidence and repeat requirements.
