#1 Guitar Tuner - Free and No Ads !
Unique features help you work out the chords to new tunes, visualize the pitch and consistency of the human voice, violin or other instrument, or answer the questions "what notes am I humming", "what are those chords", "am I hitting all the notes in tune", "is my vibrato consistent" etc. Select from a list of common instrument tunings or quickly create and manage your own using the built-in tuning editor.
Eight separate visualization modes:
1) Instrument: Combination radial strobe and string/note indicators for easy instrument tuning. Includes a database of common tunings for Guitar, Violin/Fiddle, Mandolin, Ukulele, Banjo, Bouzouki and Pedal Steel, plus a built-in editor for up to 100 user-defined instrument tunings.
2) Dial & Strobe: Combination dial tuner and innovative linear strobe for rapid and extremely accurate hands-free instrument tuning (this linear strobe is a genuine implementation of the strobe-tuner concept, not a decorative imitation).
3) Chromatic Dials: 12-way simultaneous display, with a separate dial tuner for each of the 12 notes in the chromatic scale, to visualize multiple voiced notes or chords.
4) Chromatic Tiles: 12-way simultaneous display of the notes in the chromatic scale, optimized for the visualization of rapid note/pitch changes (e.g. vibrato, arpeggio, portamento, glissando etc).
5) Spectrogram: Scrolling display of live sound analysis, showing the polyphonic perceived pitch of a wide range of sound types (including human voices and singing).
6) Chords: Grid-based estimation display of common chord types (maj/min, maj7/min7, dom7/dim7), ideal for quickly determining the 'strum along' chords for a tune where the chords are reasonably clear.
7) Partials: A multi-way strobe and waveform display, showing individual note partials along with full note timbre for detailed analysis of sound characteristics.
8) BigStrobe: A large, single strobe display, optimized for small screen devices.
These visualization modes are easily accessed by swiping the screen left/right or by pressing & holding the tuner display to get a pop-up view selection menu. User-selectable options are accessed via the MENU button or the pop-up view selection menu and include support for custom temperaments.

To tune your string instruments, such as acoustic guitar, guitar, bass and ukulele, follow the on-screen pointer and look at the note and frequency that are closest to the played string.
The spectrum analyzer provides a visual feedback of the notes played by the instrument and shows a small arrow to highlight the harmonic whose pitch the tuner is tracking.
For those who prefer to manually tune their instrument the 'Diapason' view lets you play a reference tone, 'A' (440 hz) or any other note that you can select dragging the frequency slider.
• tap to adjust the spectrum analyzer visualization options, select thicker spectrum lines, smooth out or highlights peaks, increase or decrease tuning sensitivity and precision (up to 0.1 cents)
• you can calibrate the tuner for non-standard tunings: tune the reference note, tap on the display and select 'Calibrate' to set the note as the new reference. You can also select non-standard musical temperaments, alternate note namings and much more
• select the Sonogram tab to view how the frequency spectrum changes with time, and follow the tuned note as it travels thorugh the spectrum as a green line
n-Track Tuner works great as a guitar tuner, violin, viola, violoncello, bass, piano and wind instruments tuner.

The Fine Chromatic Tuner was adjusted and tested with acoustic guitars, soprano ukulele, tenor uke and electric guitars. I believe that it will work with any mid to mid-high range instrument as it was fine adjusted for the 70 Hz - 500 Hz. So this one is not suitable for bass guitars for example. I will make a different app for the low range instruments soon.
This is automatic chromatic tuner that supports every screen size. Fine Chromatic Tuner works well with devices supporting 44100 16 bit audio input (almost every phone and tablet in mid - high price range) and 22050 16 bit audio input. It still works with the other possible settings but not so accurate.
- Automatic note selection
- Ultra responsive -50 to +50 cent range fine tuning display
- Precise to ±1/100 semitone (±1 cent)
- Analog like needle
- Exact frequency display.
- Clean and simple analog like UI
- Keep screen on while working.
- Works in noisy surroundings
- Supports A 432 Hz (Not available in the free version)
Guitar Tuner i3F in Version HD for Ipad.
Based on Fourier Algoritm is one of the best Tuner in the market, probably the most simple to use.
Guitar Tuner i3F Includes:
Scientific "A" at 432Hz and regular "A" at 440Hz
With this very easy to use guitar tuner you can tune your personal guitar and bass.
The device listen the strings of your guitar helping your finger to tune the six guitar strings.
A very sofisticaded algorithm is in the core of owr usefull tool.
On some devices you need to approach the microphone to the guitar, or better use of headphones into the microphone or guitar case. It 'be necessary to increase the volume because some phones microphones have low performance.
If the led bar just below the disoplay exceed 30% of its maximum size and the volume will be enough to move the pointer on the screen to indicate the tuning of his guitar.
"For the Android-loving musician, I think DaTuner Pro is easily the best tuner you can have on your device. I used to give that title to *see review!*, but DaTuner has proven to be so powerful, easy to use, and accurate, it'd be foolish to not use it."
DaTuner is an all-purpose chromatic tuner with a simple interface. DaTuner converts the fundamental frequency to the nearest note and error in cents for quick and easy tuning of your guitar, ukelele, violin, bass, cello, mandolin, piano, harp, saxophone, balafone, Ducati timing belt, harmonica, kazoo, you name it.
1.) No dead zone - screen changes to green when tuning is good.
2.) Auto-Sensitivity - no configuration required.
3.) Bright, easy-to-read display.
4.) Quick, accurate and precise. < 0.3 cents @ E3 (329.62Hz), <0.1 cents @ C5(1046.5Hz), < 1 cent @ A2 (110Hz)
5.) Screen lock: Lock to the note you want to tune, even if extremely out of tune and make your way up/down to it.
6.) Filter lock: Lock and filter to a specific note and filter out everything outside that note's range.
8.) Reference frequency adjustment for orchestra tuning.
9.) Choice of colours for sharp/flat
11.) Temperaments. You can modify the ones that exist or add your own using a text editor. The temperaments are saved on your external memory under the /DaTuner directory.
12.) Notation (ie Solfége, English, English sharp, English flat, Northern European.) Customization of these will be possible in a future upgrade.
13.) Emulated strobe tuner display
14.) Digital display of error in cents
15.) Pitch pipe (triangle, sine, sawtooth, square)
16.) Pitch pipe auto mode (no touch!)
17.) Accelerated tuning algorithm.
18.) Sample rate range 8kHz - 48kHz.
DaTuner's display is easy to read; nearest note and octave is displayed in a giant, easy to read font in the center of the screen, and frequency in hertz plus error in cents is displayed at the bottom of the screen. Sensitivity is auto-adjusted, but can also be adjusted by touch via a bar on the left-hand side of the screen, and the speed/accuracy of the algorithm and the relative frequency (if other than 440Hz) can be adjusted via the configuration menu.
There is no "dead zone" with this tuner app as is the case with many other apps. Instead, the whole display turns green when the incoming frequency is within a configurable range of the target frequency and you can still see small changes in pitch even within the "in-range" area. Both the "in-tune" range and the colours shown for sharp and flat can be configured in this version. The emulated strobe tuner display provides additional visual feedback to how close to the desired note you are.
Screen lock and filter lock allow you to select the note that you would like to tune to, with filter lock ignoring anything outside of the range of the note you wish to tune, which is useful for tuning in noisy environs.
I have tried my best to eliminate bugs from this software, and I apologize in advance for any problems you might find. Getting feedback via email, negative and positive, is very appreciated, so please email me all of the problems that occur so I can fix them! Try out the free version of DaTuner first to be sure that you want to buy the "pro" version.
- Doesn't detect any notes
Turn on mic auto-adjust! Ensure that the signal rises above the little yellow triangle - the algorithm doesn't run until this level is exceeded! If using auto-adjust, stop playing for a moment occasionally to allow the auto-adjust to re-sample the background noise.
There is a possibility of multiple automatic playback of the string, for more convenient operation. Configure guitar now becomes easier and faster with our application.
The application includes, in addition to the classical guitar system, configuration option "Open C", "Drop C" and "Drop D".
Guitar pitch "Open C" in the clear sounds like a chord C. If you take Barre soundings at the second fret - it will be an D (D), on the fourth fret - E (Mi), the fifth - F (F) and so on. Convenient for the game majeure chords.
"Drop C" yields even lower sound than Drop D. Such a system used by those who play heavy music. The first five strings sink to tone lower than usual, and the sixth on the two tones.
"Drop D" is suitable for those, who plays the electric guitar. Drop D differs from the usual order heavier sound, as the sixth string is tuned a tone lower.
Do not spare the stars! )) And good Luck in use!
Extremely accurate: in contrast to needle tuners that average out fluctuations, linostrobe faithfully reflects every nuance of your intonation.
Instantaneous response: if you've used Cleartune, gStrings or DaTuner before, you'll love the absence of delay here!
World-class automatic pitch recognition: reliable even for "difficult" (overtone-rich) instruments such as the mbira.
Supreme sensitivity and a clear display: you can even tune from across the room!
Note: Linostrobe requires an 800 MHz CPU or better to run well. If in doubt, you can use the free 'lite' version to check if your device is capable enough.
This full version is ad-free and offers many adjustable preferences:
⚫ adjust concert pitch from A₄ = 415 to 466 Hz
⚫ 30 historical and modern temperaments
⚫ calibrate target in cents (% of a semitone)
⚫ auto-calibrate to an external reference tone
⚫ English, German, solfège, sargam, Byzantine,
Cyrillic, and Japanese note names
⚫ support for transposing instruments
⚫ choice of sharps & flats (e.g., C♯ or D♭)
⚫ choose colors for flat, good, and sharp pitch
⚫ max. deviation (in cents) for 'good' color
⚫ adjust strobe sensitivity (rotation speed)
⚫ can display the measured frequency in Hz
Linostrobe requires the RECORD_AUDIO permission to access your phone's microphone. The audio is analyzed on the fly - nothing is actually recorded.
The Precision Strobe Tuner App's main display consists of a Strobe Display and Spectrum Dial.
The outside Strobe Display works like a classic rotating disk strobe tuner. The pinwheel pattern rotates CCW when the input is flat, and CW when sharp. When the rotation is stopped, the note is in tune.
The Central Spectrum Dial displays the input spectrum wrapped around the Dial, with each octave shown in a separate color. The Dial is marked like a clock with the twelve notes of the Scale. All partials of the input are shown as peaks in the Spectrum Dial pointing towards the corresponding notes. Use the Spectrum Dial for coarse adjustment by tuning the fundamental to the center of the selected Note Indicator. As the input approaches the desired note, a two group pinwheel pattern becomes visible rotating in the Strobe Display. Fine tuning is accomplished by adjusting to stop rotation. The Strobe Display responds instantaneously to changes in pitch and is extremely sensitive.
The first portrait screen shot shows the display tuning a Guitar D string. The fundamental and second partials show as Yellow (Octave 3) and Green (Octave 4) peaks pointing towards the Note D Indicator. The third partial shows in blue (Octave 5) pointing toward the Note A Indicator.
When Note Tracking Mode is enabled, the tuner Note Setting automatically tracks the fundamental of the incoming note. It can be disabled and the Note selected manually by tapping the desired Note Indicator. A Guitar Mode provides higher stability Note Tracking for the set of Standard Tuning Guitar strings.
Bandpass Filter Mode creates a clear Strobe Display even when harmonics are present, as when a string is first plucked. Using the Bandpass filter, the fundamental and each partial of a string can also be measured separately, so the Inharmonicity of piano strings can be determined. The Bandpass Filter can be disabled by selecting Allpass Mode from the Settings Menu.
The Precision Strobe Tuner tuning range covers all 88 notes of the piano keyboard, from A1 to C8. The Selected Note is displayed in the center. The selected Octave is also shown in the center, it's color corresponding to the color used for that Octave in the Spectrum Dial. Tap the Note Indicators to select the Note. Tap the top and bottom of the center ring to select the Octave.
The Precision Strobe Tuner can be calibrated 60 cents sharp or flat with .1 cent resolution. The next screen shot shows the Calibration Adjustment Dial, slide it sharp or flat to calibrate and stop rotation. The Calibration Setting is shown in the lower right corner. This tuning fork is .7 cent flat at room temperature.
The Temperament Mode provides separate calibration adjustments for each of the 88 Notes. This can be used to configure the PST to alternate temperaments, Piano tuning or special Guitar Intonation systems. There are five User Configurable Temperament Banks as well as several examples in Fixed Banks. The next screenshot shows a Bank configured as a Just C Major Temperament.
In addition, there are several Special Measurement Banks used for String Inharmonicity characterization and Piano Stretch Curve Calculation. Individual strings are characterized by measuring the Fundamental and 2nd Harmonic separately. By careful selection of a few representative measurement points, a reasonable smooth fit Piano Stretch Curve can be generated. Any number of measurements up to C7 can be used.
The next screen shot shows the Inharmonicity Measurements table for several strings, with the difference between the Fundamental and 2nd Harmonic graphed as a bar. The following screenshot shows the normalized and fit data, while the final screenshot shows the resulting Piano Stretch Curve in the result Bank.
For android devices, 4.1 and up.
Recommend that you try running the free Demo Version to verify operation on your device.
