Savior Guitar Tuner is a professional guitar tuner built by a touring guitar tech. It gives you the same strobe display and tenth-of-a-cent accuracy that pros rely on backstage, on a phone, fully offline, with no ads and no account.
STROBE TUNER ACCURACY
Most phone tuners round to the nearest cent or two. Savior Guitar Tuner detects pitch to 0.1 cent using a strobe-class engine that tracks the phase of the note between readings, not just a single snapshot. The rolling strobe bands slow down as you get close and freeze when you are dead in tune, so you can see a tenth of a cent of drift that a needle would hide.
FOUR DISPLAYS
• Strobe: four rolling bands at x1, x2, x4 and x8 for coarse to ultra fine tuning
• Needle: the classic meter with a wide sweep
• Cents: a clean numeric readout with a stability bar
• Trail: a scrolling history so you can watch a note settle
CHROMATIC AND INSTRUMENT MODES
• Chromatic tuner: detects all 12 notes across every octave, for guitar, bass, ukulele, violin, mandolin, banjo, brass, voice and any pitched instrument
• Standard guitar tuning (E A D G B E)
• Drop D
• Bass guitar (4 string, low B range supported)
• Ukulele (G C E A)
TUNINGS FROM A WORKING TECH
Real guitars do not intonate perfectly to equal temperament. Savior Guitar Tuner includes per-string tuning offsets for acoustic, electric, 12 string and bass that make chords ring true across the neck, the way a setup tech tunes on the bench.
REFERENCE PITCH CALIBRATION
Adjust A4 from 432 Hz to 446 Hz in 0.1 Hz steps to match a piano, an orchestra or a recording. Every string target and reference tone follows the calibration.
TUNE BY EAR
Tap any string to hear a clean plucked reference tone at the current calibration and tuning offset. Great for stage use when the mic picks up too much crowd noise.
BUILT FOR THE STAGE
• Works completely offline, no signal needed in a basement rehearsal room or a venue with no service
• Screen stays awake while you tune
• Haptic tap when a string locks in
• Six color palettes including gold, cyan, green, orange, blue and violet, with a glowing display that reads at a glance from across a dark stage
• Large note readout, frequency in Hz and cents deviation always visible
PRIVATE BY DESIGN
Audio stays on your device. The app makes no network requests, collects no data, shows no ads and has no signup. The microphone is used only to detect pitch, in real time, and nothing is recorded.
ONE PRICE, EVERYTHING INCLUDED
No subscription, no unlocks, no upsells. Buy it once and every mode, display, tuning and calibration option is yours.
