ScreenAlert
Read & Monitor Your Screen
Only for Mac
$4.99
Also Included In
Mac
New in 1.3: select an area, adjust it and see a live preview before you start. Click any alert's name on screen to pause, edit or stop it.
Turn any part of your screen into an alert.
Draw a box around a price, a build status, a score or anything else that changes. ScreenAlert reads it with on-device text recognition and tells you the moment it changes, or when a number crosses a value you set.
No integrations. No APIs. Works with any app, any window, any content.
USE CASES
• Track stock or crypto prices and get alerted when a target is hit
• Watch builds, logs or dashboards and react the moment they change
• Follow live scores, auctions or countdowns
• Get notified when a long task, download or AI agent finishes
• Make any app "alertable", even ones without notifications
SMART ALERTS
• Text changed, contains, does not contain, equals or differs
• Number equals, is greater than or is less than a value
• Image changed, with adjustable sensitivity
• Prices like $1,234.56 and 1.234,50 € are read correctly
• Reading glitches are filtered out, so alerts fire when something really changed
• Adjust the area and see a live preview of what is read, and whether your condition is met, before you start
WHAT HAPPENS WHEN AN ALERT FIRES

• macOS notification

Ratings & Reviews

ScreenAlert 1.3 makes setting up an alert faster and clearer.
NEW
• Select the area first. The alert panel opens right beside it, with a live preview of what ScreenAlert reads.
• Move or resize the frame before you press Start. Nothing is saved until you do.
• See whether your condition is met right now, for example "4,184.01, not met", before you start.
• Click an alert's name on screen to pause, edit or stop it. Paused alerts dim until you resume them.
• Pause and resume alerts from the menu bar too.
• A new welcome guide walks you through permissions and settings.
• A cleaner, more modern alert panel.
FIXES
• "Text changes" alerts now fire on values that change at every check, such as live prices. Number alerts now fire on moving values too.
• An alert's name label no longer floats above other apps.
• The frame around an alert comes back as soon as you return to its window.
• Choosing a new area on a different window now follows that window.
Thanks for using ScreenAlert. Reviews help a lot.
