Application from another web recourse.

 
Hello. How can I check if it your application or not. The thing is I can use another brokers in the Android application from this link https://fir.im/sv8k
But I don't know if these broker and application are thust worthy or not.
The name of broker in the application is BIT-live from broker searching field.
And the company name is BITCOIN GOLD International Limited.
How can I recognize if they are really those who they are or it's fake and application is fake too?

Regards
