StroboPro - Your Easy-to-Use Online Strobe Tuner for Musicians
StroboPro is your go-to online strobe tuner designed specifically for musicians. Whether you play the guitar, ukulele, piano, or any other instrument, StroboPro makes tuning a breeze. By utilizing your device's microphone, StroboPro accurately detects pitch and visually displays it, helping you achieve perfect harmony in your music.
What is a Strobe Tuner?
Imagine a classic strobe tuner with a spinning wheel and a strobe light indicating how close your instrument's pitch is to the ideal. Now, envision this process happening digitally. StroboPro brings this concept to life by digitally recreating the traditional strobe tuner experience. It displays harmonic arcs that move and rotate, visually representing the difference between your instrument's tones and the ideal pitch. No engineering jargon - just precise tuning made simple.
StroboPro Strobe Tuning Made Easy
StroboPro takes the complexity out of tuning by presenting a user-friendly interface that uses advanced algorithms to emulate the classic strobe tuner. As you play a note, the harmonic arcs will show you if you're perfectly in tune. When the display remains steady, your instrument is perfectly tuned. If the arcs rotate clockwise, you're slightly sharp; if they go counter-clockwise, you're a touch flat. It's like having a tuning expert right at your fingertips!
You Said Easy! This Isn't Easy.
Because Strobe Tuners are ridiculously precise and accurate (less than 0.1 cents), and since StroboPro tracks multiple harmonics of your instrument, it is next to impossible to get all of the harmonics to completely stop. This is especially true if your instrument, or strings, are getting old. This is OK. Try to get it as close as possible.
Fundamental and Harmonics
Most instruments don't produce a single tone when played; they produce a fundamental tone, and a series of harmonic tones that are multiples of the fundamental tone. Your ears hear each of these harmonics and the fundamental, and StroboPro shows you all of these, individually.
Speed and Position
The speed and position of the arcs around the note display indicates the difference between the ideal frequency and what StroboPro is hearing. When your tuning is getting "close," this position is generated from a direct comparison between the audio stream and an internal signal, so it works just like a true strobe tuner. Outside of "close" the speed of each arc is limited to keep it visible.
Strobe Brightness
You will notice that the strobes will fade in and out while rotating. The strength of each strobe indicates the strength of the fundamental/harmonic in comparison to the other tones that StroboPro is hearing.
Cents and Frequency Display
Unlike the position and speed of the strobe arcs, the cents and frequency displays are generated using an FFT. As a result, they will likely not exactly match what the strobes are telling you. You can use the cents and frequency displays to get close to the ideal frequency, and then use the strobes to dial it in.

Fine-Tune with Microphone Sensitivity
StroboPro is smart. It adjusts its sensitivity to filter out background noise, focusing solely on your instrument's frequencies. This means it locks onto the notes you play and ensures accurate tuning without interference.
Set Your Preferred Reference Frequency...
... to play with your friends! The default reference frequency, A4 at 440Hz, is the starting point for precise tuning. If you need a different reference, no worries! StroboPro lets you customize this setting in the options. Your last chosen frequency will be remembered by StroboPro.
Perfect Your Sound with Various Instruments and Temperaments
StroboPro understands that every musician has unique preferences. Choose from different temperaments to suit your musical style - just explore the settings to find the one that resonates with you. Plus, whether you're a guitarist, ukulele enthusiast, or play another instrument, StroboPro has you covered. It supports chromatic mode and specific instruments, each with its own special offsets to ensure accurate tuning.
Pro Tip: For those who want an extra layer of customization, you can set a custom instrument cents offset in addition to the temperament cents offset for each note.
Save Your Settings Across Devices with Google Login
Enjoy seamless access to your custom settings, temperaments, and instrument preferences across all your devices by logging in with your Google credentials. StroboPro's convenient login feature ensures that your tuning experience is consistent and personalized, no matter where you play.
Record Mode: Effortless Instrument Tuning
Introducing the innovative "Record" mode! When adding a new instrument, simply use record mode while adding each string of your instrument and let StroboPro do the work for you. StroboPro listens for the exact tuning/note of each string as you play, automatically capturing and adding the tuning information. Say goodbye to manual input - with StroboPro, your instrument's temperament is accurately recorded without any typing required.

Troubleshooting Tips for a Smooth Tuning Experience
| Symptom | Resolutions |
|---|---|
| No Sound Detected | Check microphone access and connection. Restart browser if needed. |
| Tuning Accuracy Off | Check reference frequency and instrument selection to ensure accurate tuning. |
| Not Locking to Notes | Ensure you've chosen the correct instrument or switch to Chromatic mode for a more general tuning approach. |
Why is it Free?
Of course we want to make money on this, but we also need a "market." We are true believers that StroboPro is (or will be) one of the best tuners on the market and can command a premium, but we need the market first. As engineers, and not marketers, our plan is to grow virally first, and then release our premium features via subscription. We aren't good at the TikToks... but you are. If you make a video tuning your guitar/double bass/ukulele etc and tag it with #StroboPro, let us know and we will gladly add you to our list of testers and provide you with a complimentary full version when it becomes available.
StroboPro is now in testing on mobile!
