I forgot to mention why a classical pre-roll would be tricky in my previous post

.
In fact, the loop is not necessarily tempo-driven by a click track. So in these cases, I would have to guess the tempo, which is quite tricky. I could invalidate the behaviour for non tempo-driven loops, but I try to keep the app as intuitive as possible, so a loop is always considered as "time driven" and not "tempo driven".

I also thought that a Bluetooth footpedal would be the best solution for remote access but I assume this would be restricted by the same limitations you mentioned.
Bluetooth is even worst ^^ ! I think an iPhone can only be paired with bluetooth headset/headphones and nothing else.
I thought about the ext control again after your question, and I think I may have find a way to emulate a switch pedal. But don't expect anything about it soon, and it's a 100% tricky DIY thing anyway.
For the earpiece, there is an option for that. In "Options", in the last category named "Output", the "Favor Speaker Over Receiver" switch do just that. If you enable it, sound will go out through the Speaker at the bottom of the phone. So it'll be louder, but sensible to feedback.
Maybe the word
Receiver is not clear enough.
Earpiece make more sense to you ? I'm not a native english speaker, so if you are, I'm interested in your opinion

I'm really glad that you had fun with the app

! It's my main goal, so it's really appreciated !
Don't hesitate to rate and comment it on the app store by the way, it helps me a lot
