Use psyhical button to control ESP8266 device

Let me ask one simple question:
I have one ESP8266 device with push button, so if I press this button , I want to controll android device, concrete I want to start certain app on that device, is that possible with blynk, if it is not, does anybody knows way to do it.

or maybe,

controll virtual push button (widget) wich is created with blink?

THX!

Search for IFTTT, I think it may be possible?
