Poor
Immediately confronted with sideways on view of everything. Then, whilst trying to make sense of why there were so many boxes, some already containing numbers, presumably by way of example, and with a baffling combination of colons and equals signs between them, I was just about to experiment to find out when rudely interrupted by some kind of request to grant permission for further distraction and some irrelevant mention of Google which could be explored to discover how I'd be further interrupted and how my information was going to be used if I granted such permission. Err, no thanks: I can't be bothered with all the fuss. I prefer apps which just do the job. Afterthought: I should add that I never actually got around to experimenting with some numbers!
