I’ve had a number of enquiries through various channels about whether we’ll make the SFE available as an app for mobile platforms. The answer is that we would like to, but that finishing the SFE text and getting the website working properly has to be our priority. So this is probably off somewhere in next year rather than this year. And, to be clear, we’d almost certainly have to charge for apps (unlike the website, which would remain free.) But with those provisos, here’s a small poll to ascertain demand, and which platforms our readers use. Comments also welcome, of course.
