Helix Tuner vs Cab ML
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Helix Tuner
This app offers a novel approach to instrument tuning by visualizing sound as an interference pattern. It avoids pitch detection, instead creating an optical illusion of motion that indicates sharpness or flatness, appearing stable when in tune. This method is highly resistant to background noise and harmonics, providing clear tuning information even in noisy environments.
- Visual interference pattern tuning
- No pitch detection
- Optical illusion of motion for tuning
- Stable visualization when in tune
- Resistant to background noise
- Useful in noisy environments

Helix Tuner is a completely new way to tune your instrument. Unlike all other tuning apps, it does not detect your pitch at all. Instead, it combines the sound coming into the microphone with the desired tuning pitch to create a beautiful interference pattern on the screen. The interaction between your sound and the reference pitch creates an optical illusion of motion when your note is sharp or flat, and it appears stable when you're in tune. If you are tired of digital tuners that jump around erratically, have slow or delayed response to changes in your tuning, or in general just don't give you good tuning information, then Helix Tuner is the one you are looking for. When you manually select the tuning note, as opposed to letting the app detect it automatically, Helix Tuner is extremely resistant to background noise and higher string harmonics that confuse other tuners, causing them to jump around to higher notes and give wrong tuning information. Because the visualization system naturally responds more clearly to sounds near the selected tuning pitch, it is useful even when other musicians are playing nearby.
Cab ML
This app generates custom impulse responses using a neural network, allowing interactive sound shaping. It also includes a poweramp and microphone reverb generator for further audio manipulation.
- Neural network impulse response generation
- Interactive tag-based sound shaping
- Poweramp with multiple options
- Microphone reverb generator
- AUv3 plugin support

Cab ML is both a standalone app and an AUv3 plugin that provides a neural network for impulse response generation. By moving tags in a window you can change the impulse response in an interactive way. Underlying a neural network will generate an impulse response based on the position of the tags. Instead of trying out all your impulse response files through a classic impulse response loader, you can now find the right sound interactively by moving the marks until you like what you hear. Furthermore Cab ML also provides a poweramp with many options and a microphone reverb generator. The free version allows you to test Cab ML completely, but every minute the plugin will be silent for 3 seconds. To remove these limits there is a one time in-app purchase. You need an audio interface to connect your instrument to your Mac. Known audio interface brands for guitar or bass are for instance Focusrite or iRig. If you don't have an audio interface, you can use the AUv3 plugin in a DAW such as GarageBand or Logic Pro. Any (guitar/bass) sound you have recorded can be fed through the Cab ML audio unit.

Verdict
The clearest difference is price: Cab ML at Free against Helix Tuner's $15.99. Cab ML also leads on update cadence (every 3 weeks vs every 4 months). Helix Tuner's advantage is rating (4.8 vs 4.0) and review sentiment (90% vs 50%). On ads and device support there is nothing between them.
