Can't guarantee the same for the apps on phones though as they are often software solutions based on general phones so it depends on how the software has been written. Regarding how accurate are digital tuners, they are based on quartz crystal oscillators that usually are easily accurate to 50 parts per million so, essentially, they are very accurate. For the final tuning, I did let it cool down between grinds and checks just in case the temperature had a significant effect. It's certainly not changed it noticeably. I was easy to keep both tines the same length by eye and the sustain on both seems the same as it was before. It wasn't touchy either, it's not critically minute amounts taking off, just don't go daft. It's not rocket science or even heavy engineering. Just got my guitar chromatic tuning meter and used my bench grinder to take equal amounts off the tines' ends a bit at a time until the frequency was right.

The fork also now sounds good when played simultaneously with an mp3 of a 440 Hz tone to check for beats. A little more fine trimming of the length of the tape with some sharp scissors, and I got the fork to measure within +-1 cent of 440 Hz, as measured against several calibrated iPhone tuners (both dial and strobe). Wrapped the new lengths of tape on the fork tines, and the fork rang 3 cents flat. Then I cut some tape strips about 9/29ths as long (actually a few mm longer). So I removed those pieces of tape and carefully measured them. That also lowered the frequency, by only a bit too much, to 20 cents flat. Next I tried a couple strips of masking tape wrapped around the very end of the each tuning fork tine. Two big rubber bands on the tines clearly lowered the frequency. So I played science student, and tried the experiment.
Each fork is triple tuned for accuracy of +/. All of our high quality tuning forks are Made in the USA. Use this fork to tune any musical instrument to concert pitch A440.
