ABSeq - Reference Test Music 4+

I reference mixes as I work on them using Apple headphones connected to my phone, but I’ve just used the Files app until I found this. It’s a huge upgrade being able to a to Files, instead of bouncing back-and-forth between opening different files. I think the audio quality is the same as the Files app on the iPhone, but it may be slightly different. My only critique would be to make sure that the audio quality is exactly the same as the audio files, so that you’re not getting a warped perspective of what things sound like.

This app is missing the most basic feature of an AB test app - the ability to blindly evaluate two audio files.

To me, the goals of an AB test are to:

1. determine if one can hear a difference at all between the files

2. determine if one has a preference for either of the two files, or can blindly identify them by sound alone.

This app is so close to being extremely helpful, but it’s extremely feature-bare for the wildly high price of $15/year.

Here’s how it should work in my view; the app has three buttons: A, B and X. You import two files. The names are hidden from the user but retained by the app. The two files are randomly placed on one of the three buttons, and a duplicate of one of the files chosen at random is placed on the third button.

You listen to the three of the files, and depending on the mode, you are asked by the app to either identify which file is which, or which file you prefer.

You repeat this process perhaps 5 or 10 times, with new randomization of the above factors each time. Then, the app reveals to you how many times out of 10 you chose each file as the favorite, or how many times out of 10 you correctly identified each file.

I would be happy to pay $15 for an app that does this well, similar to ABX Tester on Mac. However, this app lacks every single feature necessary for me to derive any value from its AB test functionality.
