My DHd App

The DHd annual conference packs sessions, talks, posters and workshops into a programme that is hard to survey as a PDF or a long web page — and harder still on a phone between two rooms.

The task

Build a companion that opens up the full programme and lets a personal schedule emerge from it: quick to operate, available on the move, and with no obligation to register.

The approach

The programme can be filtered by day and time slot, and sessions, talks and posters can each be bookmarked individually. The “My programme” tab shows only what has been saved, sorted by time. A person index covers all speakers and chairs and leads straight to their contributions; individual sessions can be shared by link.

Bookmarks are always written to the browser first, so the app keeps working when the conference Wi-Fi does not. Anyone who wants to can add an account and sync their selection across devices, backed by a lean Flask service with SQLite.

The outcome

A tool that does one thing and needs no installation to do it. Offline-first here is not a slogan but an order of operations: local first, cloud second and only if asked.
