Call apps
Enabled
If you aren’t planning to use OpenIn for handling tel:
links on your Mac, you can disable it completely, so OpenIn will
not try to check if other apps are set as the default for handling call links.
Applications
Remove all applications
OpenIn automatically discovers applications that can be used as call apps on your system. You can remove all applications and rebuild the list on your own.
Add application…
OpenIn shows a dialog with all the applications that can be used as call apps found on your system. If you are planning to rewrite the URL to a different scheme, you can add it here.
Select applications from the Add applications list and press Add to add them to the list of applications for call apps.
You can add the same application more than once - that helps, for example, to configure them differently.
Order of the applications
OpenIn uses the defined order of the applications when it shows the App Selection menu when you click the link.
You can change the order by dragging applications by ≋
.
Edit application

Edit applications
Based on the type of the application, you might see slightly different configurations.
- Name - you can give any name to the application; it does not change the name of the app on the system.
- Icon overlay - you can add an icon overlay. This is useful if you, for example, add the same application with different configurations.
Launch Configurations
You can configure how OpenIn launches the application
- New instance - Whether you want the system to launch a new instance of the app.
- Adds To Recent Items - Whether to add the app or documents to the Recent Items menu, if the application supports that.
- Activates - Whether the system activates the app and brings it to the foreground. You can uncheck this to launch the URL in the background.
- Hides - Whether you want the app to hide itself after it launches.
- Hides Others - Whether you want to hide all apps except the one that launched.
Rules
Rules help you organize how OpenIn uses selected applications. If no rules are defined, it will show the selected
apps in the App Selection menu when you click the tel:
link. Similarly, if no rules match conditions, OpenIn will just show
the list of applications from above.
In the list you can edit or remove rules.
Order of the rules
The order of the rules matters. OpenIn goes from the first rule of the list to the next one, verifying if the conditions are met.
The first that matches conditions will be executed. You can change the order of the rules by dragging ≋
.
Edit rule

Edit Rule
You can configure the Name of the Rule to help you identify it. If you aren’t satisfied with the rule yet, you can Disable it while trying to figure out what works best for you.
Conditions
You have several conditions to configure. If you have specified multiple conditions they will work as AND, except multiple phone matches and multiple sent-from apps are executed as OR in those lists.
Execute when
- With key Modifiers - you can configure this rule to execute only when those key modifiers are pressed when you click the link.
Execute with Focus
OpenIn can be configured based on the selection of System Focus. OpenIn cannot read which focus is set, but you can configure Focus Hints parameters that you can use with the Focus editor in the System Settings. And when the Focus Hint matches the one configured in the rule, this rule will be executed.
To learn more, please review Tutorial: Configuring rules based on the Focus selected in macOS system.
Matches phones
You can add one or more phone number matches. In case you configured multiple phone numbers, just one of them needs to be matched.
Use *
for matching.
Sent from apps
You can configure this to execute this rule only when a tel:
link is sent from a specific application.
In case you configured multiple applications in this list, just one of them needs to be matched.
Use applications
You can configure how this Rule shows applications defined in the list of applications.
- All - all applications from the list will be used
- All (running) - only running applications will be shown. If none of the applications are running, this rule is skipped.
- Selected - only applications that you have selected in the list will be used.
- Selected (running) - only running applications that you have selected in the list will be used. If none of the applications are running, this rule will be skipped.
Custom script
You can define your custom JavaScript to change the URLs or select the call apps based on your own custom conditions.
