TASCAM Settings Panel for Audio Interface

I own both an iPhone 11 and a Tascam 16x08 and on my laptop (which is broken) I look to the settings panel to make my drums sound high quality. When the laptop broke I switched to my iPad Air 2 to do my tracking through GarageBand and it’s been fine, but I truly would love to have my settings panel available before sessions. Is there a reason this application isn’t available on my iPhone 11 or iPad Air 2?

This app provides with basic settings: stereo/mono monitoring choice. It works however it would be nice to have settings related to sampling rate/buffer size (similarly to the ASIO driver)
