Q: Does this app have HDR merging function (e.g. .HDR file)?

No. Please use any other merging apps.

Q: What is ISO parameter?

100-1600. You can change it from setting menu.

No, it's not supported. S/SC does great job for photography and much less expensive. Main advantage of V is 4k video recording.

Q: Why it's so slow?

That's due to hardware limitation. This app cannot do anything.

Q: Can I turn off wifi during capturing?

No, it doesn't capture anymore. The camera is fully controlled by this app via wifi.
