Description
Never miss a call, text, or notification again! Flash Alerts Ultimate turns your phone's camera flash into a powerful visual alert system.
Key Features: • Flash alerts for incoming calls, SMS, and app notifications • 5 unique flash patterns: Standard, Heartbeat, Strobe, Gentle, and Urgent • SOS emergency signal — send a Morse code distress flash with one tap • Shake to Flash — toggle your flashlight by shaking your phone • Do Not Disturb schedule — set quiet hours with no flash alerts • Low battery flash warning — get alerted when battery is running low • Flash alarm clock — wake up with gentle light flashes • Fully customizable flash timing, blink count, and patterns • Per-app notification filtering — choose which apps trigger flash alerts • Battery saver mode to preserve power
Ideal for people who are deaf or hard of hearing, or anyone in noisy environments. Flash Alerts Ultimate provides a reliable, customizable visual notification system for every situation.
Download now and never miss an important alert again! Accessibility Service Notice: Flash Alerts Ultimate uses Android's Accessibility Service on older devices (Android versions prior to 4.3) as a fallback to detect incoming notifications and trigger flash alerts. This service is used solely to detect when a notification arrives — it does NOT read, store, or transmit any message content or personal data. All processing occurs locally on your device. The app does not use the Accessibility Service to change device settings, collect personal data, or interfere with other applications.
Recent changes: Fixes alerts that silently stopped working: the app now restores its own notification access when the system had granted it but stopped delivering notifications. Adds a screen flash for devices without a camera flash, and updates the app for Android 16.

★☆☆☆☆Therese S· Jul 26, 2026
The test button doesn't do anything. I can't tell if it will flash my screen or not. The only use I need this for is SMS which I have from my phone, actually my phone doesn't alert me to incoming SMS either, it's just too darn "subtle" for my taste. So this app might help with that, if I could get it working on my tablet that I normally use for work and at home.
