Altrillio

Altrillio listens to your voice and tells you, honestly, whether you produced a rolled R. No grading. No guesswork. Just yes or no.

Built for adults learning Spanish, Italian, Portuguese, German, Russian — anyone whose target language uses a rolled R. The feedback is real-time, runs entirely on your iPhone, and works regardless of which word or language you attempt.

WHAT'S INSIDE • Practice — tap, attempt a rolled R, get an honest verdict the moment you stop • Five exercises — drills that build the underlying skill, in order • Camera mirror — optional, watch your own mouth while you practice • Personal best — your longest sustained trill, kept locally
