Anything useful is behind a paywall

Along the lines of the other reviews. It's frustrating that there is an initial cost, and then when you open the app, there's a memmo telling you to subscribe at extra cost. The app itself is pretty decent and easy to navigate. But the subscription fee annoys me. I can understand the reasoning that's provided for the fee , but surely a free download, and then a 99p would be less of kick to the old chap ?
