Android and iOS mobile app working with esp32 - Arduino

Good day, I am interested in ordering an app to control an RC toy. Assumption app installed on smartphone, Android and iOS. Control by WiFi in the toy ESP32-Wrom 32 and l298n bridge, two DC motors and mini servo.

App in the form of a virtual joystick. Supporting 2 types of vehicles: 1) direction operated by servo (proportional) drive by motor A and B controlled by bridge also proportional to joystick swing. Rear and front. The possibility of calibration of the straight position. 2) Tank type vehicle controlled by motor on the left and right side of the vehicle. Proportional control. Possibility of joystick calibration, sensitivity and blind spot.
