I am a Chinese, and I am embarrassed to admit that some of the English "translations" provided by some ( not all ) Chinese manufacturers are atrocious. Useless, at best.
That said, without being able to read the instruction you received, I cannot be sure whether you misunderstood or just simply garbage instruction.
If you can take screenshots of the instruction and post them back here, it will help.
Meanwhile, a little "drone 101" :
A drone usually comes with a controller which is used to fly the drone.
However, there are drones that require a phone in stead of a controller to fly the drone. But that is not common.
I am assuming the drones (copters) you received are camera drones. That will require a phone to connect to the drone's camera so that when the drone flies, the camera will transmit what it sees instantly back to the phone. You will then see what the drone sees at the same time.
In order to do that, you will need to download a particular app ( software) to the phone.
The app is used to connect the drone's camera to the phone by way of wifi connection. Without such app, you won't see what the drone sees.
The controller does the flying. You do NOT need the app to fly the drone. You just don't get to see what the drone sees.
The user manual ( instruction) will tell you how to download the app. The app is FREE.
That's all I can help without reading the instruction you received.
