It depends on what the app does. There is no simple answer like "it will
take x days".

Everything(!) is different. Depending on how they developed the app, it
would be neccessary to use Kotlin or Java instead of Swift. It's also
not very likely, that the app is using a cross platform framework like
Capacitor with Angular - because then they would already have an app for
Android devices too.

As explained above: everthing is different, not just the brand of the phone.

> me. In PC language, only the drivers would have to be changed, because

No, there are no "drivers". The app uses Bluetooth to communicate with
the device. An Android version would "just" have to implement the same
features - but with a completely different programming language on an
operating system which is based on Linux und Android instead of iOS.

It is like porting a native Windows application to MacOS or Linux - this
is also not an easy task, if you did not use cross platform tools like
Qt or Electron.

Even if the creators would know what to do - someone has to pay that.
And I would not expect much less than at least 50000-100000 USD for that
(2-3 months of development and testing for around 1500 USD per day -
minimum).
