On-Device A/B Testing Framework for Mobile Apps
Seed: experiment_registry, rollout_percent, metrics_events; example: local overrides with remote config and exposure loggingADVERTISEMENT - IN-ARTICLE
Implementation Guide
Design an on-device A/B framework that evaluates feature variants locally, logs exposures and events, supports secure remote config, and reconciles exposures on intermittent connectivity. Include SDKs for safe randomization, sticky assignments, and guardrails for experiments impacting critical flows. Provide tooling to export exposure+outcome for causal analysis.
