We (Guardian Project) have been developing "panic button" features in our apps for years, and now we are working to make a more flexible and open ecosystem of apps that can both trigger other apps, or respond to triggers. Since banking should be as private as possible, Bankdroid is a natural panic responder app, for example, by having Bankdroid lock when the "Pattern Lock" is enabled and a panic message is received. This setup allows for easy configuration of a single trigger action which can then trigger multiple apps.

You can see an example of this user experience in this video: https://www.youtube.com/watch?v=mS1gstS6YS8
It is simple to implement, here are some examples of other apps:
The first panic button app that sends this kind of trigger is called Ripple, and it is available here: https://github.com/guardianproject/ripple https://play.google.com/store/apps/details?id=info.guardianproject.ripple
I'm adding support to this app right now: https://panicbutton.io/ https://play.google.com/store/apps/details?id=org.iilab.pb
