Retro Tuner is a musical instrument tuner for the iPhone, iPad, and iPod Touch. It features a user interface in the style of an analog panel meter and Nixie tube note display, but below this retro surface are all-new digital signal processing algorithms that determine the pitch of your instrument quickly and accurately. Retro Tuner was written by the owner of several crappy guitars and a 1920s player piano that is constantly going out of tune, with the idea that if it can tune those, it can tune anything. Retro Tuner tunes in equal temperament and can handle the full 88-key piano range. The reference pitch defaults to A=440 Hz and can be adjusted via Settings either as a frequency in Hz or as a detune factor in cents.

UD Tuner costs $1.99 and Retro Tuner $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
UD Tuner holds the better App Store score, 4.4 against 3.5. That said, the two scores are not equally well evidenced: UD Tuner has 22 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of UD Tuner's written reviews are positive against 63% of Retro Tuner's, so the app with the better star average is not the one people write more warmly about.
UD Tuner ships an update every 7 months, Retro Tuner every 9 months. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
