WhatAn app that gives users granular control over government emergency alerts — filtering by severity, location relevance, and time-of-day quiet hours — on both stock and custom Android ROMs.
SignalUsers are frustrated by being woken up repeatedly by non-critical emergency alerts broadcast at the highest priority level, with no ability to filter or schedule quiet hours on their devices.
Why NowGovernments (particularly Canada) have been escalating use of presidential-level alerts for non-life-threatening situations, and the backlash is growing as people disable all alerts entirely — creating a public safety problem.
MarketSmartphone users in countries with aggressive alert systems (Canada, US); ~100M affected users. No incumbent solves this — OS-level controls are binary on/off with no nuance.
MoatWeak — this is a feature not a company. Any OS vendor could add granular controls. Low defensibility.
