The best pitch detector for most singers is one you can open right now — no download, no account, no cost. The free browser-based pitch detector on this page works on iPhone, Android, Mac, and PC using your device’s built-in microphone. Open it, allow microphone access, and sing — you’ll see your pitch, note name, Hz value, and cents deviation in real time within seconds.
If you specifically need a native mobile app with offline access, recording features, or MIDI export, the comparison below covers the top iOS and Android options in detail. But for the vast majority of singers who want immediate pitch feedback during practice, the browser tool is all you need.
Try the Free Pitch Detector First — No Download Required
Before installing anything, try the free tool at the top of this page. Here’s what it does that most paid apps charge for:
- Real-time note detection — displays the exact note name and octave you’re singing (e.g., G4, Bb3) updated at ~60 frames per second
- Cents deviation meter — shows how many hundredths of a semitone you’re above or below perfect pitch
- Frequency in Hz — the raw vibration rate of your voice, updated live
- Pitch stability score — measures how consistently you hold a note without wavering
- Vocal range tracking — logs your lowest and highest detected notes across the session
It works on iPhone (Safari), Android (Chrome), Mac, Windows, and tablet — any device with a browser and microphone. For a deeper singing-focused analysis with a scrolling pitch curve showing vibrato and drift, use the voice pitch analyzer. To find your voice type with a guided high-low test, use the vocal range test online.
What Makes a Good Pitch Detector App for Singers?
Not all pitch detection tools are built with singers in mind. Generic chromatic tuners — designed for guitar or bass — often show the wrong octave for singing voices, especially male voices which commonly read one octave too low. A singer-focused pitch detector needs:
Accurate octave detection — must identify whether you’re singing C3 or C4, not just “C”. Generic tuners fail here regularly for male voices and high sopranos.
Low latency — feedback must arrive in under 100ms to be useful during live singing. Delays longer than that break the ear-voice feedback loop that makes visual pitch training work.
Cents display — professional pitch work requires seeing deviation in hundredths of a semitone, not just “in tune / out of tune”. Understanding what cents mean in music tuning is the foundation of serious intonation training.
Vocal frequency range coverage — the tool must reliably cover at least 80 Hz (bass low notes) to 1,100 Hz (soprano high notes), with stable detection across the full range.
Clean display — a cluttered interface that requires your attention to read defeats the purpose. The display should be readable at a glance while you’re focused on singing.
Privacy — your voice is personal data. A good pitch detector processes audio locally on your device with no server upload. For details on how this works technically, see the guide on privacy-first pitch detection.

App-by-App Review
PitchDetector.com (Browser — Free)
The fastest way to start. Open the page, allow microphone access, and you have a full pitch detector running in under 10 seconds with no installation. Covers the full vocal frequency range (80 Hz–1,100 Hz), displays note name, Hz, cents deviation, and stability score simultaneously. Works on every device with a modern browser. The voice pitch analyzer adds a scrolling pitch curve for vibrato and drift analysis. The pitch accuracy checker adds a scored session assessment. Privacy guaranteed — no audio ever leaves your device.
Best for: Any singer who wants to start immediately. Daily practice sessions. Singers on multiple devices. Anyone who doesn’t want to install and manage apps.
Nail the Pitch — Vocal Monitor (iOS and Android)
The most feature-complete native app on the list. Nail the Pitch provides real-time pitch tracking with note names and frequency, records your singing, and exports melodies as MIDI — which makes it useful for songwriting as well as practice. Pitch accuracy is high, typically within a few cents. The interface is more complex than simpler tools, which suits singers who want detailed technical feedback.
Best for: Singers who want recording and MIDI export alongside pitch detection. Songwriters building melody ideas. Users who need full offline functionality without any browser.
Vocal Pitch Monitor (Android — Free)
A lightweight free Android app that displays a real-time 7-octave pitch graph. Simple to use with no learning curve — open the app and it starts detecting immediately. Records and plays back practice sessions. Lacks the detailed cents display of more advanced tools but covers the basics reliably.
Best for: Android singers who want a no-cost, no-setup option for basic pitch feedback during practice.
Pitch Checker (iOS — Paid)
An iOS-specific app with frequency, octave, and waveform displays. Adjustable sensitivity suits different singing styles and microphone setups. Useful for analyzing vibrato and pitch stability in detail. The waveform display gives a visual sense of tone quality alongside pitch accuracy.
Best for: iPhone users who want detailed pitch data including vibrato analysis and waveform visualization.
Singscope (iOS — Free / Paid)
A graph-based pitch visualizer aimed at beginners. Easy to read and interpret, with the core pitch feedback displayed clearly without a cluttered interface. The free version covers basic pitch tracking. Good entry point for singers new to visual pitch feedback.
Best for: iOS beginners who want simple, clean visual pitch feedback without technical complexity.
Vocaberry (iOS and Android — Free / Paid)
Focused on vocal identity rather than pure pitch accuracy. Vocaberry identifies your vocal range and voice type, then suggests songs that match your range — useful for singers still figuring out which repertoire suits them. Less suited for moment-to-moment intonation training, more useful for exploration and song selection.
Best for: Singers exploring their voice type and looking for song recommendations matched to their range.
Browser Tool vs Native App — Which Should You Use?
The honest answer depends on exactly what you need:
Use the free browser tool when:
- You want to start immediately without installing anything
- You practice on multiple devices (phone, tablet, laptop) and want consistent access
- You need a free solution with no ongoing cost
- Privacy matters — no app permissions, no account, no data collection
- You’re happy with Chrome, Safari, or Edge on any device
Use a native app when:
- You need full offline access with no internet connection required
- You want to record sessions and review them later within the same app
- You need MIDI export for songwriting or composition
- You prefer a home screen icon and app-style experience on mobile
For the vast majority of singers who practice with wifi available, the browser tool covers everything a native app does — without the installation, storage, or cost. For a full comparison of browser vs app pitch detection including technical trade-offs, see online vs app: why a browser pitch detector is enough.
How to Get the Most From Any Pitch Detector App
Whichever tool or app you use, these practices make the sessions more useful:
Practice in a quiet space — background noise is the single biggest source of inaccurate readings across all pitch detection tools. Even a modest reduction in ambient noise dramatically improves stability.
Use an external microphone if possible — built-in phone and laptop microphones introduce more noise and coloration than even a basic USB condenser mic. The best headphones and mics for pitch training guide covers specific recommendations at different price points.
Hold notes for at least 2–3 seconds — pitch detection algorithms need a minimum sustained duration to produce stable readings. Quick notes and fast runs will always give noisier data than sustained tones.
Watch patterns, not individual readings — a single reading jumping sharp doesn’t tell you much. A consistent pattern of sharpness on every G4 tells you exactly what to work on. Keep sessions focused on 5–10 minutes of deliberate work rather than long unfocused singing.
Warm up before testing your range extremes — a cold voice reads artificially narrow and is more susceptible to strain at the edges. Use vocal warmup exercises before any session involving high or low notes.
Pair pitch detection with ear training — visual feedback accelerates learning but shouldn’t replace ear development. The interval ear training page has exercises that build the aural skills that make visual feedback easier to act on.
