AlertFlow – Precise call alerts that override silence for important contacts

Summary: AlertFlow enhances Android's Do Not Disturb by allowing selective call alerts from specific contacts on Cellular and WhatsApp. It features a "Greenlist" to override silence locally and a "Flow" safety net that triggers alarms if VIP calls are missed, all while maintaining offline privacy.

What it does

AlertFlow creates a customizable local Greenlist to let calls from chosen contacts bypass silent mode on Cellular and WhatsApp. Its Flow feature triggers a full-screen alarm if a call from a Greenlisted contact is missed and not returned within a preset time. Focus Mode locks volume to zero when needed.

Who it's for

It is designed for users who need to block unwanted notifications but cannot miss calls from specific people such as family, clients, or colleagues.

Why it matters

AlertFlow solves the limitation of Android’s Do Not Disturb by enabling precise control over call alerts, ensuring critical calls are never missed without compromising privacy.
