Would you mind telling me how you rate Jellop? I see them on a lot of successful Kickstarters, and would love to hear about the real experience of them.

It wouldn't take much more to make this useful for older people, e.g. farther non-obvious separation of buttons (e.g. across pages), or in time. Humans are really bad about associating unrelated things from too few samples or missing recurring things just outside our window of attention.
