Corneteiro

Corneteiro is an educational app created to help military personnel memorize 27 bugle calls, hymns, and songs.

With a simple and objective interface, the app gathers the calls in one place — with audio, name, and tips for each (most of them) — and offers an intelligent simulation for you to practice until you master each command.

How the simulation works:
Listen to the call and identify it. The app records your correct and incorrect answers and applies spaced repetition: the calls you get wrong appear more frequently, and those you already master, less often. This way, your training focuses exactly where you need to improve the most.

In the hymnbook section, create your own hymns and songs. Paste the YouTube link and lyrics into the specific field, save, and listen to the hymn while following the lyrics.

What you'll find in the app:
• List of 27 bugle calls
• Audio of each call to listen to whenever you want
• Tips (memorization tips) for most calls.

• Simulated in classic or multiple-choice mode
• Track your progress by touch
• History of your latest results
• Light and dark theme support
• Change the app color to match your institution's colors.

• Hymnal - Save your hymns and songs in one place.

All data is stored on your device. The app does not collect personal information, does not require registration, and works without an internet connection.
