Timer+ 2.4 and up can be launched via a URL scheme. iOS allows apps to register URL schemes that can be used by apps to launch other apps and pass basic data in the URL parameters. There are many automation and launcher apps, such as Alloy, Launch Center Pro, and Workflow, that use URL schemes to enable powerful workflows.
Here are the two actions that Timer+ supports via URL schemes.
Set and start a quick timer. Quick timers are timers that are deleted after they are completed.
Start a quick stopwatch. Quick stopwatches are stopwatches that are deleted after they are used.
Timer+ partially supports the x-callback-url specification. It accepts the x-source and x-success parameters. If x-success parameter is set, Timer+ will attempt to open that URL after completing the action specified by the URL. For more information on x-callback-url, visit x-callback-url.com.
To enable x-callback-url support, start your URLs with "timerplus://x-callback-url/" instead of the standard "timerplus://app/".
