Hi (again) Joshua !
This is a quite rare problem due to some audio and multitasking bad interaction. I have the same problem with Spotify sometimes. I've filled a bug to Apple about that.
Luckily there is a far more easy workaround than restarting the phone.
The problem (if it's the same) only occurs if you relaunch Everyday Looper after already having launched it. In other words, when it's in the "recently launched" app list appearing when you double click the home button.
You can simply hold down a finger on the Everyday Looper icon in that list (appearing at the bottom of your screen), wait for the little minus sign to appear and tap on it. That will force Everyday Looper to launch itself from scratch the next time. You then just have to launch it again.
Hope this helps

!
