See how it went.
Inspect output, exit codes and timings. The task table shows last and next runs, health across five recent executions, and average duration. Enable or pause tasks with a switch.

CHOOSE YOUR ACTION
Everyday tasks.
Room for your own ideas.
Your own automation.
Run shell scripts or AppleScript. Set a working directory, environment variables, timeout and output limit for the work you need done.
Keep an eye on a page.
Check a web address for changed content, or open a URL in your preferred browser. Open applications and folders on schedule, too.
Set the mood.
Play a playlist, track or artist from your Music library, resume what is ready, or pause Music. Set volume and Mac display brightness to an exact percentage.

A FEW USEFUL DETAILS
Before you schedule.
Does it need to keep running?
Yes. Closing the windows leaves Do This Then active in the menu bar. Quitting stops scheduling and cancels pending follow-ups. Occurrences missed while the app is closed or the Mac is asleep are skipped.
Does it save my scripts and logs?
Task definitions are saved locally. Persistent run logging is off by default: recent results stay in memory until you quit. Turn on saved history in Settings when you want it. Web-check baselines are saved separately so checks can remember previous content.
What counts as a changed web page?
The web check compares the downloaded response body. Its first successful run establishes a baseline. Later checks return 1 for a change, 0 for no change, and 2 for an error. It does not run JavaScript or use your browser’s cookies, and changing timestamps or ads can count as changes.
Can tasks run on top of themselves?
A task never overlaps itself. Extra occurrences are skipped while it is already running or queued. Up to four tasks can execute together, with foreground actions serialized. Circular follow-up chains are rejected.
Which music can it play?
Choose a playlist, track or artist by name from the Music app’s library, or resume whatever is ready. Artist playback uses a dedicated playlist managed by that task. Music and AppleScript actions may need macOS Automation permission; volume and brightness depend on hardware support.
What does this website count?
Visits, pageviews and download requests, using a short-lived random tab token and daily aggregate counts. No cookies, third-party analytics, stored IP addresses or stored user agents. Counts are requests, not unique people or installations.
