Introduction in Readme.md is incorrect

The introduction in the `Readme.md` says the following:

> Wirelessly transfer files to and from file transfer ready BluetoothA Bluetooth Low Energy File Transfer native iOS app written in Swift for Adafruit Industries. This app will make it accessible to send files via BLE (Bluetooth LE) to your Adafruit hardware on the go!

I believe it should say:
Wirelessly transfer files to and from file transfer ready BluetoothA Bluetooth Low Energy File Transfer native **Android** app written in **Kotlin** for Adafruit Industries. This app will make it accessible to send files via BLE (Bluetooth LE) to your Adafruit hardware on the go!

Open Readme.md and review the introduction quoted in the issue. Correct the platform and language references to Android and Kotlin, then verify that the introduction accurately describes the PyLeap Android app.
