Respir is a web app that provides guided breathing exercises with visual and audio cues. It offers 3 preset breathing exercises and a breath holding test, but users can also create custom breathing exercises using their own timings. Custom exercises are saved locally and can be exported and imported as JSON data.

This project was created for the 2024 IPC Winter Hackathon by me, shibest, and ben-6. We won best overall.

Respir is built with SvelteKit and uses browser localstorage for persistence. The most challenging part of this project was creating the breathing exercise controller and animations. Originally I relied on javascript setInterval functions, but I eventually switched to using requestAnimationFrame to ensure accurate timings and frame-perfect animations. Due to the relatively simple functionality, we were able to focus on making the UI and UX as smooth and intuitive as possible.
