1. 4/5Super great... Except one thing

   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

2. 5/5Almost Perfect

   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.

3. 5/5The absolute best!

   It is such a luxury to be able to use this app on a tablet and benefit from the humongous screen, compared to the relatively small screens on most tuners, even strobe tuners. I used to own a Conn strobe tuner. That was an old analog beast, and it made lots of mechanical noise all by itself. This is even more accurate and totally silent. If you set intonation on your instruments yourself you absolutely need a strobe tuner, and this is a very elegant option because of the ability to use a tablet size screen. There is a learning curve when using strobe tuners because they are so sensitive. It is essential that you study up on this before you dig in or you will wonder why the notes don’t stabilize. It’s actually because the notes do not stabilize on your instrument. They are moving constantly as harmonics jump out and die away, so you need to know how to use the tuner and what indicates a note is in tune. Most other types of tuners filter out those jittery fluctuations, which seem to make tuning fast and easy, but actually give you a much less accurate assessment of what the string is doing. Because strobe tuners are so superior, they show you everything that is going on and you have to know how to read it. Is extremely simple once you get the hang of it and well worth the effort for an instrument that plays in tune all over the neck. ***BEST RESULTS I RECOMMEND USING THIS WITH AN AUDIO INTERFACE FOR PLUGGING IN YOUR INSTRUMENT IF IT HAS A PICK UP. YOU WILL BE REWARDED WITH SMOOTHNESS AND ACCURACY. I AM USING A FOCUSRITE WHICH IS BUS POWERED FROM MY TABLET AND IT IS A FABULOUS EXPERIENCE***

4. 2/5Good as a phone app bad for my use cases

   I purchased this app based off of good reviews here and on Reddit. From the day I purchased it I’ve been disappointed by the issues I’ve had. On my M4 IPad Pro it almost always displays the hz multiple octaves up (frequently double.) Also I cannot get my interface for my guitar to work with this app. It’s recording and sending input to the iPad but nothing is coming through to the app. I’m not sure if this is even meant to be supported but I resorted to trying it considering I could never get it to work normally. On my iPhone 15 Pro the app works almost seamlessly if I put my phone extremely close to the guitar. Any further away and it can’t hear it even on boost mode with the noise filter on. I tried turning them off and no input. It jumps octaves much less on the phone but it still does it frequently enough to be annoying. Some of this could be user error but I didn’t change any settings after downloading the app. In general the app works well enough and I’m sure the good reviews reflect good experiences. I just didn’t have a great experience myself.

5. 4/5Luthier’s Review

   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.
