Hello Im a Beginner in Arduino, me and my teacher are looking for a way in which I can make a mobile app where I can enter some information and then click a button connected to the arduino an receive back the information. I bought an Esp 32 in order to make this connection but I dont know if it is the best option.

I'm a bit confused. "mobile app" implies a phone, "arduino" implies an Uno, nano or Mega, and then you also mention ESP32.
Which is the Arduino intended to communicate with - the phone or the ESP32?
OR, if you just mean a connection between a phone and an ESP32 (without any Arduino) do you want to use WiFi or Bluetooth?

It probably isn't but, since you have already bought it, any currently available WiFi terminal app should work with it, thereby saving you from re-inventing the wheel.
