Small tools
for learning
and meeting.
Motitory makes apps for people learning a language and people trying to find time together. The server knows only what a feature needs; sharing happens only as far as you choose. We pick what lasts over what sells ads.
What we make
See all
KotoSense
Japanese grammar for Korean speakers. Understand the difference between patterns that translate alike, in context. No account, no server, no ads.

WhenWeave
A private calendar and a finder for the free time two people share. Show others only "busy", propose a time, and one tap puts a single event on both calendars.

HangulSense
Korean grammar for Japanese speakers. The sister app of KotoSense, it tells apart Korean expressions that become identical in Japanese. Working title.
What we keep
Private by default
No server where none is needed. Where one is, it knows only what the feature needs, and sharing happens only as far as the user chose. The app does not hide things; the server never sends them.
Explain the why
Not the right answer, but how the meaning would change had you picked another. Not the feature, but what is visible to whom. We choose what leaves understanding behind.
No nagging
No streaks, no leaderboards, no endless notifications. We promise no exam results, and unreviewed content says so on the screen.
