Professor Caloiro Digital Products LLC is an Iowa-based app development studio building focused, practical tools for learning European Portuguese — starting with listeners, learners, and expats who want real fluency, not just flashcards. The studio is currently in early development, building its first apps for iOS with Android to follow on Google Play.
What we're building
Small, purpose-built apps rather than one bloated platform — each one solving a specific gap in how people practice a language:
Pronunciation training that adapts to your own voice
Practical vocabulary and grammar drills grounded in real use
Tools designed for learners immersed in Portuguese life, not just studying it from a textbook
More on each app as they near release.
