Defragmenting the calendar

Product design for Aerotime, a YC-backed macOS calendar that merged task tracking and scheduling into one surface.

Led design for a YC-backed productivity app that reimagined the calendar as a place to prioritise work. It combined task tracking and scheduling to help teams reclaim focus time and get things done.

Focus time Ask busy people when they do their real work, and you'll hear the same answer: in the evening. Their days fill with meetings, leaving deep work stranded in half-hour gaps. Aerotime made focus time a priority, protecting it as the week evolved. People told us they won back up to 20% of their day.

Scheduling Finding a time shouldn’t be hard work. No more endless scheduling emails or impersonal booking links. Tell Aerotime who to meet, and it figured out when. It reshuffled meetings that could move to optimise your day. Fewer meetings at better times, and focus blocks long enough to get things done.

Tasks Work turns up in a dozen places. A thread in Slack, a ticket in Linear, an email that quietly becomes a task. In Aerotime all of these appeared in a unified Inbox, letting users prioritise their work and make time for it. Tasks that needed uninterrupted attention had focus blocks waiting for them.

Impact Over three years, Aerotime went from Chrome extension to polished Mac app. In the end, it didn't get enough traction. Calendar apps were having a moment in the early 2020s, but few survived. Many of these features are now part of AI-first workflows.

Robin is one of the best designers I've ever worked with. Although we formally worked together through a consultancy arrangement, he operated like a core member of the team and effectively led design at Aerotime.

I always admired the structure he brought to product thinking and his exceptional understanding of design primitives, which made him a brilliant UX designer. At the same time, he has extraordinary visual taste. He has a rare ability to create interfaces that feel clean and minimal without ever becoming sterile or boring.

Very few designers combine rigorous UX thinking with such a strong aesthetic sensibility, and Robin does both exceptionally well.
