Flash Alert (Calls & SMS) vs SMS Filter
Side-by-side comparison of two open source alternatives
Flash Alert (Calls & SMS)
Flash Alert turns your camera flash into a powerful visual indicator whenever you receive a call, SMS/MMS, or notification from another app (WhatsApp, social media, etc.). Key Features: - Customizable flash alerts for calls, messages, and apps. - Contact filtering: enable the flash only for your contacts. - Battery-saver mode: smart deactivation if the phone is face down or if the screen is already on. - Night mode and "Do Not Disturb" override options. - Ambient noise detection (for compatible Android versions). A lightweight app, privacy-friendly, and completely ad-free.
SMS Filter
SMS Filter can filter incoming SMS messages before they reach your inbox. You can filter by address, and optionally add parts that must occur in the message for it to be blocked. By default, SMS Filter will not delete incoming messages. You will get a silent status bar notification when SMS Filter has filtered an incoming message, which you can view by opening the notification or by opening the application. You can also tell SMS Filter to delete incoming messages, in which case it will happily do so for you. To do this, just turn off the 'Save messages' preference.
