The physical products are great, however the app leaves a lot to be desired. I think it's fine as a free app, but a paid version with a lot, and I mean a lot, more development effort would be great. Not another subscription for a product we already own, just a really solid paid app that includes a functionality where Saturday isn't a week day if the schedule started on Friday evening. And if the change affected the ongoing schedule. Not the next one with the same settings.
