KeyTuner

TimperTuner is a full-range accurate and easy to use chromatic tuner that gives clear feedback with a visual design that makes maximum use of the screen. A consistent horizontal display for fine and coarse tuning allows easy tracking of the needle as a note is played. The display is suitable for both tuning and intonation practice. A quick tune mode provides fast confirmation in live situations. Three color schemes allow one to choose from a white, warm, or dark background for comfortable viewing. Tone generation is also supported for droning.

An advanced digital algorithm is used to allow precise tuning of all instruments (strings, woodwinds, brass, plucked string, etc). Many tuners have difficulty with low registers (such as bass and bassoon) or those with many overtones but TimperTuner employs algorithms specifically aware of harmonic distributions. By taking advantage of the real-time behavior of multiple waveforms, vibrato can be detected and is shown as a highlighted region around the needle.

Fast and easy to use

Really handy for my piano, and saved me from calling the Tuner. The app is fast, and intuitive to use. The range is impressive. And I will try it with violin next. Nice touch with the dark theme mode.

User friendly and accurate!!!

Rating screen is annoying

I really like this app and think it’s excellent however I did not want to put a rating in at this time but the rating screen kept coming up like an annoying mosquito you swat away with your hand. Each time I had to put down my cello bow and tap”NOT NOW”even though I hit not now several times it became so annoying that I decided to give it 2 stars and write this review based on the fact that you have to rate the app to use it for more than 30 seconds. I would expect that from a free app but I actually paid for this one.
