I use Vyrso for reading in comfort on the iPad. But it keeps losing the page I'm reading and going back to some previous point. It has done this particularly with Spurgeon. And if I type in the number of the page from which it hijacked me, it refuses to take me to that page. Very frustrating. Yet I choose Vyrso on iPad for my e-reading app, feet of clay and all - tho I;ll be so happy if and when these teething problems get sorted out.
Incidentally a Users guide would be a great help. I don't find the programme very intuitive. I solve most of the problems that crop up by trial and error, but it would be much quicker and less frustrating if I had some idea what I was supposed to be doing!
Having complained, I'm aware that this is a free programme, and I'm grateful for it.
