Know the quality behind every app listing.
AppScore turns noisy iOS and Android storefront data into one explainable benchmark for quality, privacy, maintenance, and execution.
The methodology
Six signals. One transparent score.
Every component is normalized to 100 and exposed in the response. No community popularity, paid placement, or opaque editorial adjustment enters AppScore.
Rating confidence
Bayesian weighting rewards durable satisfaction, not tiny samples.
Maintenance
Release freshness reveals whether an app is actively cared for.
Efficiency
Binary size is compared with a category benchmark.
Privacy
Store labels, Exodus trackers, and permissions expose data cost.
Localization
Case-insensitive language consolidation measures global reach.
Polish
Screenshots, tablet support, and platform coverage show execution depth.
Developer-first API
Trigger once. Poll or receive a signed webhook.
Audit jobs run asynchronously through a regional worker. Every callback includes an HMAC-SHA256 signature, and every endpoint accepts a scoped live or test key.
