Resumo

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).…

Ler o restante

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).

Descrição

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.…

Needs Android notification-listener permission. Global Application: any Android user. LatAm Version: Brazil/Mexico Android share is high; PT-BR/ES templates for WhatsApp groups and delivery apps.

Jobs to be done

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.

Bianca · 27 · Recife: Gets 300 notifications a day, mutes groups manually. Frustration & buying signal: Wants calls loud and everything else quiet in one place; would pay a one-time fee.
