Audio Evolution for Android Website
Audio Evolution Mobile Studio TRIAL on the Google Play Store
I have Audio Evolution Mobile Studio for Android; A full-fledged Digital Audio Workstation with individual tracks up to 24 or more I think. MIDI, functionality with USB Audio Interfaces (it worked with the behringer UMC404HD). I highly recommend this to anyone who has an Android device and wants to record something high-quality on a budget. There are some features that you have to buy in-app (like DLC for a game, kinda stupid) but it's still affordable.
I have honestly considered downsizing from my Desktop Workstation and laptop with Reaper and just using Audio Evolution for demos and recordings before I take them into the studio just because it works well. I'm definitely going to try and implement it for a mobile-workstation set-up.
I haven't used iOS in years but I know the newer versions have GarageBand pre-installed, which is pretty cool from a musicians stand-point.
Hope this helps.
Here's the trial version

Another thing to note is that this works best in a tablet as the layout can be a little compact, but if you have a device with good processing power, it operates like a breeze regardless
All right, update.
Baofeng uses the Kenwood connector - the "speaker" pin is wired to the tip of a 2.5 mm jack. I found a 2.5 mm > 3.5 mm jack cable (from my AT headphones). But you can't plug it into a phone jack socket, because the microphone pin gets shorted to ground with a regular 3-pin jack. And my 4-pin jacks are still en route from China.
So I plugged a cheap $1 USB sound card (plastic blue noisy trash) with line in and out via an OTG adapter into my phone. Finding an app which would allow me to record and monitor (listen to) the audio at the same time was a feat. Audio Evolution Mobile Studio works well so far, but because of its nature (multitrack "pro" studio), it's a bit cumbersome.
When I finally got out to capture some transmissions, I spent half of the pass fiddling with cables only to find, that my earbuds weren't working. Oh well, at least I can repurpose the cable for the 4-pin jack.
With the item you give, yes on my Nexus 10. Make sure you have a phone/tablet with USB OTG. With this cable: http://www.amazon.ca/gp/product/B005QX7KYU?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00
And I have done my recording with this: https://play.google.com/store/apps/details?id=com.extreamsd.aemobiledemo
Streamer setup typically means you want to broadcast yourself to twitch or youtube, and that's quite some additional stuff on top..
Recording on Android isn't really all that advanced/usual thing to do. https://play.google.com/store/apps/details?id=com.extreamsd.aemobiledemo claims to have a special low-latency driver for usb interfaces, but it looks like the Katana can only be used with 44.1kHz - but at least it works in a quick test I did Works to multitrack-record the DI along with the wet stereo signal. Trial version is limited to 45s recording via the USB driver, but that's enough to test. Paid version is 9€ + 4€ in-app-purchase for the low-latency audio driver. If you only record yourself over a backing track, then the default android USB-audio driver will also work, despite the higher latency.
But recording on a tiny phone is not really comfortable, not sure whether the tab7 is large enough for the UI to be useful.
As to playing over backing tracks: just feed those in via aux-in (to have it output via the speaker) or feed it in via USB (then you'll only be able to hear it using the rec/headphone out)

On Android you can use Audio Evolution Mobile.
You will have to disable MIDI support in the settings to make the Katana work and depending on your device, it might not work well at all.
You will also need an OTG adapter and a device that supports USB OTG.
The app that I linked is a free demo which should be enough to see if it works for you.
I don't own an iPad so I can't help you there.
maybe this
audio evolution mobile has a tool that can check if a USB interface is working with your phone.
There is this new one as well, that seems to be less limited than fl3
