In short: absolutely.
Our overall goal is to make Spectre available from as many platforms as possible. Our current road map has us focused on iOS at present, with a minimal web demo already functional, as you've already discovered. As soon as iOS goes live, our focus will switch to developing a fully functional web app.
Our goals for the final web app is a solution that is easily accessible online, available as a progressive web app, and can also be downloaded and used offline, such as from a USB stick or otherwise.
Happy to hear your thoughts or suggestions should you have any.
