Thanks for the positive feedback! I'm glad you're finding it useful.
Out of interest, where did you find SEQUEmatic? Was it in search results or did you find a link on another website?
I started with a website because it was simpler and could be used from any device - mobile, table or computer. I have been exploring some options for a mobile app but it is still some way off before it can be shared. To help shape the app, what would be the most important features for you?
Also, if anyone else is interested in an app, please comment here so I have an idea of how popular it would be.
