Persistent Background Volume Booster for Android & E-Ink Devices

The user on a Boox Go 7 (an e-ink Android tablet) is frustrated that most volume booster apps do not run persistently in the background, specifically noting issues with boosting audio for browsers like Edge Canary. This highlights a niche need for a robust Android audio enhancement solution that can reliably operate as a persistent background service, overcoming Android's aggressive app management. Such a SaaS product could offer device-specific optimizations (e.g., for e-ink tablets), ensure consistent volume boosting across all apps (especially browsers), and potentially integrate with automation tools like Tasker for power users. This solves a common pain point for users of less conventional Android devices or those who need continuous audio modifications.
