Sight-reading skills open the door to reading written music and familiarizing yourself with various music styles. Sight-reading is not a daunting task, and with sufficient practice, anyone can develop this valuable skill.

Our app is designed to help you quickly identify notes across every part of the fretboard, with a special focus on positional playing.

By enhancing your sight-reading abilities, you'll find it easier to focus on other musical aspects like harmony and rhythm.



- Four different modes of use:
1. Locate notes on the fretboard based on the notes in staff.
2. Locate notes on the fretboard based on note name and pitch.
3. Find the names of notes on the staff (without the fretboard)
4. Identify the names of notes presented on the fretboard.

- Automatic detection of problematic notes.


- Key signature support, from 1 to 6 sharps or 1 to 6 flats.

- Automatic selection of the enharmonic notes for each scale to prevent double sharps or double flats in the key signature.

- Scales include major, minor, melodic minor, harmonic minor, blues, pentatonic, and all modal scales.


- Support for 4, 5 and 6 string bass guitars.

- Frets are grouped to limit the number of notes to practice and test.

- Predefined fret groups, e.g., 0-3, 4-6, 7-9, 10-12, 0-12, 13-17, etc.

- You can define custom fret groups.

- The highlighted fret group is displayed on the fretboard.

- Your sight-reading progress is tracked per fret group.

- The longest streak record per fret group measures your sight-reading accuracy.

- You can select specific strings for the highlighted area.

- Test notes can be limited to naturals or notes from a selected scale.


- Reading ahead is a crucial skill for effective sight-reading.

- You can adjust the number of notes to read ahead.


- Several alternate tunings are available for 4, 5, and 6-string bass guitars.

- Optional extra treble clef for iPad.

- Support for left-handed bass guitars.

- Option to display the fretboard in perspective (in landscape mode).

- A universal app compatible with iPhone, iPad, and iPod Touch.

- Supports all screen sizes.

- No ads or in-app purchases.

Great Sight Reading Trainer

I truly enjoy this tool. As someone who’s coming to bass from keyboards and drums this tool has been exceptionally helpful in drilling sight reading for the bass fretboard.

I actually use the app regularly

I’m using this app now to learn the first 5 frets one string at a time. Illuminates small sections of the bass clef.

Best iPhone trainer out there

This app is great for advanced or beginners. It's the perfect app to fill 30sec while waiting because it makes you a better player.
I first used it because I was primarily a 4 string bass player and wanted to learn the 5 string. It allowed me to learn the fifth string incredibly fast and the knowledge surprisingly transferred to an actual 5 string bass very easily.
For those more advanced I advise putting the timing to fastest speed and using the app. It's great for learning areas of the bass that you are weak at, even if you don't touch the exact note every time it still trains your brain where all the different note options are which is the whole point anyway.
