Our Philosophy
Less Coordinating. More Together.
Modern schedules are fragmented across work calendars, personal appointments, family obligations, and side projects. Answering the question "When are you free?" usually triggers an exhausting back-and-forth across chat apps.
The Social Inversion Principle
Traditional shared calendars ask users to surrender their privacy by exposing full appointment titles, doctor visits, and meeting notes. UsTime flips this paradigm:
Client-Side Scrubbing
Your device converts private appointments into anonymous busy blocks on your phone before anything is transmitted.
Overlap Heatmaps
Our mathematical Interval Inversion Engine calculates the exact overlapping free slots across your entire circle.
Built for Real Life
Circles for Every Bond: Create dedicated spaces for your partner, friend groups, book clubs, or family dinners.
1-Tap Web Guest RSVPs: Friends without the app can view recommended meetup times and cast their vote with a single tap.
