iStroboSoft 4+

I see this app hasn't been updated in quite a while which is fine, because I think it's actually pretty close to perfect. I bought the hardware version (stroboplus hdc) and have a couple stroboclips, but honestly I prefer the app... The display is quicker and more accurate than the stroboplus and it's more powerful than the clips. HOWEVER, at some point, it seems to have lost the ability to rotate upside down, which is something I used all the time! It made it easy to have a power cable coming out of my phone and still have the display in portrait mode, offering the most visibility of the strobe. It was super easy to have it plugged in and sitting on a music stand or desk. Also I feel the mic pointing upward helped the tuner hear the instrument much better. Please bring this feature back!!! It seems like such an easy fix!
Sincerely,
a longtime user and fan

Bottom line, this tuner is everything the pros say about it. Since I only play guitar as a hobby (I find it to be somewhat less confounding than golf), I can’t add anything to the “learnedness” of their comments. I’m sure I’m only scratching the top layer of the surface of the capabilities of this app too. I do know it’s more accurate than any other tuning gadget I’ve ever used, including an A tuning fork, a gizmo that looks like a weird harmonica (guitar pitch pipe), the Intellitouch clip-on, and built-ins for my guitars and amps. I need to read up on some of the other things it can do, because I’m not doing anything other than tuning my guitars with it.

I was going to give it 4 stars instead of 5 because the screen often jumps around uncontrollably, especially when tuning the low E string. It don’t remember it happening when I first got the app (though it might have). That means I have to guess at where the sweet spot is a lot of the time. This happens with all of my guitars. It’s probably something I’m doing wrong because I’ve not read about anyone else having this problem. Since it’s probably due to “user incompetence”, I didn’t feel right taking away a star from a review that I’m probably not even qualified to write in the first place. I need to look into that cable I read about in some of the reviews. It’s not usually loud when I’m tuning, but I’m wondering if that would fix my “jumping around” problem.

I have been a luthier for 30 years and have been using my Stroboconn for that long. I wanted something equivalent and portable. I wrote my first spectrum analyzer (FFT) for hardware I made in 1984 running on a Mac+. I have a lot of expectations when it comes to this software. With in app purchases I had to spend $30 to replace the mechanical strobe which seems expensive for an app. It does, however, function very well. Make sure to calibrate it. I also spent an extra $10 for having the spectrum features replacing my Mac+. (Well worth it.)

I would really like a power meter feature. Beyond tuning I often need to measure string to string balance in piezo pickups. The other feature I would love to have is a waterfall display of the spectrum. It would be an easy add.
