I paid for the premium version hoping for some improvement, but the sensitivity is very inconsistent.
Sometimes the app picks up its own been, showing a .04 sec time. Sometimes the app picks up the sound when removing my pistol from the holster. And sometimes, it picks up nothing at all.
Some guidance and repeatability is really needed here. I think airpods compatibility would be beneficial here to get a mic closer to the pistol, and further from a holster.
