Thank you, this is very helpful. One thing I really like is the ease and simplicity of doing everything on the iphone, I had not yet put much thought into how this would be different using a separate device.
The main reasons I was considering a separate device for recording are:
1) My Iphone storage is limited because I have a lot of photos and documents for work
2) I am often listening to music on my BT headphones that are connected to my iphone. The phone does not let me listen to music while recording video.
So I may be better off continuing to use my iphone and instead find alternate solutions like increasing cloud storage, off-line back-up, etc. I can probably just find another cheaper separate device to use for listening to music via bluetooth so that my phone can do the recording.
So thank you, this was helpful!
