If you have an iPhone/iPad, since iOS 11 is possible to connect the phone directly to your computer:

And you can use Lemur for example.
I use Lemur on the iPad all the time for mixing/recording/remixing on the fly, and best of all, the entire interface can be rearranged to your liking on the computer. It might be a bit cumbersome to set up, but there's no lag whatsoever. It's $30 on the App Store, and the desktop counterpart is free.
The Glitch Mob performed with iPads on their Love Death Immortality tour, however they were using them as controllers using the Lemur app.
Sorry about the filter; not my photo.
This is all running in Ableton Live (32bit) on an i7 with 16GB of RAM.
Not shown: Vocal looping pedal. ART USBDualPre interface.
I'm still working on setting up Lemur, and plan to get two expression pedals for the APC.
Both platforms match each other pretty well with most general mobile features, except for one area in particular - audio apps and audio processing (and by audio apps, I mean apps that require real-time processing / creation of audio - not streaming audio / mp3 playback).
iOS has been much further ahead in this area for quite a while, though Android has been promising improved audio latency for years. It is still much more difficult to do realtime low-latency audio processing on Android than it is in iOS. Latency is still too high for many popular processing apps, for example Amplitube Guitar Processor - which is still iOS only.
There are also many pro-sumerish level control apps that are only available on iOS, for instance Liine Lemur and Apple's own Logic Remote app for iPad.
I have, and Lemur is a good open source effort, but it's not really in the same ballpark as Touchable.
Lemur is more a way to connect to MIDI servers and design very general MIDI and OSC tools....it's best to think of Lemur as more of a "language/framework" for tools people build.
So you install Lemur, and then you have a LONG road ahead of you to have a usable, reliable midi controller. The best Ableton Lemur template is live control 2. Its got a couple of the features touchable ships with, such as a few X/Y controllers you can map, a session view where you can see clips, and some rough attempts at device control .

Touchable is basically the much better, more flexible, and more reliable "midi controller" for IOS and Android working with Ableton.

Personally, I use my ipad pro and iphone 7 plus heavily in my production and live setup, but I haven't used Lemur in years.
Your best available tools, imho:
Cheers
Touchable 3 has been the best that I've found, but it's not working with the latest version of Live. Next up would be Lemur with LiveControl 2. Lemur is only $9.99 through tomorrow, so you might want to hop on that-much better than the $50 I paid in 2013.
I'm thinking the same thing, it looks to be a great starter system and the Shuttle Control can do great things with Live Control. Never used one...yet. https://liine.net/en/products/lemur/premium/livecontrol-2/
Rip. I bought lemur back when it was first brought to ipad, which was... nearly a decade ago, at this point.
Plenty of relevant info here if you wanted to dig more into it, but while it was certainly the first in its field to provide what it provides, and was widely used for a reason, there's now plenty of clones and lookalikes that are slightly more modern that are probably worth looking into instead.

is amazing for this kind of thing. Design your own interfaces. No Bluetooth support though sadly, but will work over network midi afaik. I'm not sure there is a protocol for bluetooth control across iOS but I could be wrong.
Thank you!
The iPad is running Lemur . It’s an insanely cool MIDI controller. It used to be a separate hardware controller that cost a fortune, but with the advent of smartphones and tablets it was released as an iOS app for $50. You need to know basic C scripting to program it but you can do some really crazy stuff with it. There’s a built in physics engine which is really fun and gives you options that no other controller (that I’m aware of) can offer. It runs connects via a small iConnectMIDI 2+ interface that’s behind the yellow synth on the left. It isn’t visible in this shot, but it’s also really cool. In addition to its MIDI functions it has 2 channel audio passthrough meaning you can route the audio output of the iOS device through the USB connection avoiding the garbage built in DAC on the headphone output of the iOS device. This allows you to use iOS synth/instrument apps while capturing the audio at full quality in your DAW. Hope this answers your question.
you can also use things like lemur for ipad, or touchable/mashable, host of other apps to send midi over wifi. I use it and it works pretty well, minimal latency in osx. https://liine.net/en/products/lemur/
Not only is this entirely feasible, but people actually use Max to control things like servos and LED arrays. It's very powerful as a control language and not just for MIDI/Analog music gear. You can learn all about it at the Max/MSP forums.
If you have an iPad there's also Lemur and MidiDesigner. There are tons of cool templates that people have made for both apps.
Midi designer is iPad only. I have no experience with Android, but there's Lemur: https://liine.net/en/products/lemur/
A lot harder to program than Mididesigner, but looks a lot cooler and works cross-platform.
