How to receive data sent by ESP-01 8266?

I want to write an app that receives data sent by ESP-01 8266 and that ESP-01 is connected to the same phone hotspot. What is best way to achieve this? First, you need to setup your ESP as a client (ST_MODE).

Can a ESP-01 connect to an AP?

In STA mode, the ESP-01 can connect to an AP such as the Wi-Fi network from your house. This allows any device connected to that network to communicate with the module. The third mode of operation permits the module to act as both an AP and a STA.

What does the ESP8266 Esp-01 Sta mode do?

It simply establishes a two way communication between the ESP8266 and the device that is connected to it via Wi-Fi. In STA mode, the ESP-01 can connect to an AP such as the Wi-Fi network from your house. This allows any device connected to that network to communicate with the module.
