Babylon
You check your watch dozens of times a day. Babylon turns every glance into a micro-lesson: a smartwatch that teaches you numbers in a new language, one telling-of-the-time at a time.

Numbers are where new languages stall
People starting a language want to begin with numbers: prices, times, dates are the first real-world test. But number drills are exactly the practice that apps make tedious. Numbers already surround us on a device we glance at constantly. What if the watch simply told the time in the language you're learning?

Three psychological needs, one watch face
Together these pointed directly at the watch's unique functionality: passive exposure that compounds, with the time itself as the flash card.
- Autonomy: progress without surrendering the day to an app.
- Stimulation: practice in fresh, unforced moments.
- Competence: a small, real win with each glance.
The best learning interface is the one you were already going to look at.
design principle
A watch first, a teacher second
The research was translated into the watch-face behavior, the pairing of numerals with their written forms, and the restraint that keeps Babylon a watch before anything else.
