Only for 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 Combine any of these: • macOS notification • Sound, once or until you stop it • Text spoken aloud • Run any macOS Shortcut • Copy the text to the clipboard • Open a URL with the recognized text • Send a webhook RUNS QUIETLY IN THE MENU BAR • Run as many alerts as you need, each with its own color and name • Alerts are saved and come back after a restart • Click an alert's name on screen to pause, edit or stop it • Manage all alerts from the menu bar • Follow a window even when it moves or is covered • Alerts pause while the Mac sleeps or the screen is locked • A colored frame and name label show what is being watched READ AND COPY SCREEN TEXT • Read any area aloud with the voice and speed you choose • Copy text from anywhere on screen, even from images and videos • Global keyboard shortcuts for reading, copying and adding alerts HISTORY AND EXPORT • Every reading and every fired alert is logged • Export to CSV PRIVATE BY DESIGN • Text recognition runs on your Mac with Apple's Vision framework • No account, no tracking, no data collection • Nothing is sent anywhere unless you set up a webhook yourself • One-time purchase, no subscription Available in English, Greek, German, French, Spanish and Japanese.

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.
