1. 5/5First time DIY success!

   My tuner for my Steinway M recently passed away and as I looked for someone else, I thought why not go down the rabbit hole and see what it would take to tune it myself. After a lot of research, I decided to give it a try, if nothing else I would learn more about my instrument. I purchased a high end tuning hammer and some mutes, and decided to go with PianoMeter for the app. It was recommended to me by another pianist/tuner, and I believe it was what my previous tuner used. For the basic paid version it did everything I needed and was far less than the other professional tuners. While it took me about 6 hours to do my first tuning, it was a lot of fun and ended up sounding great! There are definitely things one needs to learn with experience, such as setting the pin and tuning unisons, but this app and all of the great documentation and video walks you through the whole process. Anthony the developer was very responsive and helpful with a few questions I had. I can’t say enough good things about the app and support, I highly recommend it!!!!

2. 5/5Outstanding diagnostic tool!

   I am a Piano tech for more than 30 years. I’ve replaced tune lab pro with Piano Meter Pro as my main diagnostic app. There are a few problems with an occasional partial slip but no more than any of the other apps you can get here. NOW the big thing on this app is the graphic depiction of every note on the piano lined up with a keyboard. This gives me a visual representation that I can show to a non musician client. I sample each note into the Piano Meter App, then I take a screen shot, at the end of the tuning I repeat the process. Now I have a before and after picture for the client. Of course, the picture is a gimmick if the tuning’s not good. But this app gives me constant feedback about what the piano is doing during the tuning. Great for pitch correction! Curves are consistent to curves calculated with other diagnostic tools. Oh yeah, you do have to upgrade to professional to get those features that makes it great for the professional piano tuner. Wholeheartedly recommend!

3. 5/5Good tuning app with regular updates

   Nice looking UI, frequent updates & automatically calculated tuning curve on the fly: Awesome. I bought the 1 year pro subscription to do a pitch raise on my in-laws very out of tune piano, and it worked very well. I’ve also recently purchased a used Yamaha U1 which I’ve timed twice in 3 weeks, first a rough pass after it was moved to my house and it acclimated, then again to fine tune it. I was first discouraged that it took like 5-6 hours to do the first rough pass, but the second pass a week later went way faster (like half the time) as I starting to get the hang of the order of the tuning pins and the much smaller adjustments for fine tuning. What also helped speed up is to not focus so much on the number of cents too high/low, and setting a threshold in your mind, but rather getting the rotating “discs” to stop spinning. Interesting is that after the first rough pass, the bass strings sounded very shallow and I was really bummed, then I pulled up PianoMeter again to check and the mid range was all about 2-3 cents too high (either from the accumulated change of tension across the piano or me just tuning it slightly sharp while focusing too much on the numbers). So after tuning it that second time, the bass strings resonated beautifully again. I very much recommend this app. I’ll probably tune my piano myself from now on, and more frequently than once or twice a year. I totally recommend this app.

4. 5/5Great app

   The developer has worked very hard on this app and it shows. I have a few piano tuning apps and this is probably the most simple to use and most streamlined app of all of them. There is another review here complaining about the stretch compared to Yamaha keyboard. This isn’t fair because most Yamaha keyboards use concert grand pianos as their samples and this will be very different for what a smaller piano needs to be tuned to. Every piano is tuned differently. This program gives excellent tunings in the bass section based on the particular inharmonicity of the piano. Some short pianos just sound bad no matter what you do or what app you use because of the poor scaling or other factors. I tell my clients who have picky ears to download this app to help them touch up tunings on their own because of the price. The plus version is a no brainer for the picky piano owner who can’t wait for their tuner to come by.

5. 5/5Great app

   Original post: I've been turning my own Baldwin 5 foot 8 inch grand since the early 1970s. Using just a tuning fork. Neither the bass stretch of piano meter or piano scope is pleasing to me. I'm experimenting with tune lab trial version which gives much less stretch. But tune lab has other flaws which I'm trying to correct for. Using the pianometer app as reference– Full version. Update: at this point I'd say I prefer the stretch of pianometer, plus I don't have the patience to keep retuning the bass. I think my initial dissatisfaction was because the 1974 book I learned to tune by did not incorporate any stretch in its method, plus I was mostly playing Bach then which is confined to the middle 4 octaves . at the moment I'm only playing my own composition which uses octaves in the deepest bass. Now that I've gotten used to it it seems fine. So I've changed my rating to five stars. Makes the tuning process much simpler.
