Cromatika is an Android application designed to train and improve pitch accuracy in a clear, visual and practical way.

It includes a precise tuner for different instruments and, in addition, a specific mode for working on the human voice, where pitch accuracy percentage and progress are recorded session by session.

What can you do with Cromatika?

Voice Mode (male and female)
Select the appropriate vocal range and the note you want to practise. The app calculates the accuracy percentage and saves each session so you can track your real progress.

Instrument Tuner
Includes categories such as woodwind instruments, brass instruments, guitar and bass. It works as a clean and direct tuner, showing the detected frequency in real time without saving percentage records.

For guitar and bass, you can complete the full tuning sequence in seconds: choose the note and, once it is correctly tuned, the app automatically switches to the next string, allowing fast and organised tuning.

Reference Playback
Press “Play” to hear the selected note as a guide before performing it.

Real-Time Visualisation
Watch on the graph how the detected frequency behaves compared to the correct pitch, with clear reference lines showing whether you are above or below.

Session Results
Check the average percentage achieved, the number of notes practised and the history of previous sessions in voice training mode.

Light and Dark Mode
Clean and adaptable interface for a comfortable experience based on your preference.

Cromatika is a tool designed for singers who want to improve their pitch objectively and measure their progress, while also serving as a practical and precise tuner for instruments.

Visual, direct and focused on real pitch accuracy.
