Summary

Briefing

A Reddit poster (Ideas Radar, Oct 22) wants real per-app control of notifications and sounds and has not found it; the same post ran in two Android communities. Android's per-app channel settings exist but are scattered. Existing tools found: volume managers that switch volume by foreground app (Volu, WOW Volume Manager, Audio Profiles).…

None found with notification-level policy rules on one screen (limited check, not exhaustive). Mass B2C utility, global, SEO-friendly ('silence Instagram notifications but keep WhatsApp loud'). Low-confidence idea; demand evidence is one Reddit thread (post volume is demand, not proof that no product exists).

Description

Product: Android app that builds a single policy matrix (rows = apps and categories such as calls, messages, social, promo; columns = loud, normal, vibrate, silent, hidden) and applies it through notification-listener and channel APIs; templates for work hours, sleep, driving; 'why did it ring' log to learn rules; monthly 'noise report' shareable card.…

When my phone buzzes for everything and I miss important calls, I want one screen of rules by app and category, so I can stay reachable and calm.

Risks

Main risk

Low willingness to pay

All risks

Value Risk: Attention — Low willingness to pay. Next: Fake-door price test. | Usability Risk: Supported — Simple matrix UX. Next: Prototype. | Feasibility Risk: Attention — Permission friction and OEM battery killers. Next: Test on 5 OEMs. | Viability Risk: Elevated — Google/Samsung can ship it. Next: Move fast on templates and SEO.

Next validation step

Fake-door page + 2 Android community posts; check native features
