Needs some improvement

Great catalogue of resources but the current version of the app for me doesn’t seem to keep track of where I was up to in a book. Every time I start the app I have to scroll through multiple chapters to get back to where I was. The other bug I’ve found is when starting the app while reading a book I’ll be presented with a blank screen and have to close the book and reopen it for it to render again

Constantly Improving

I love the Safari service, and the iPhone app (I don’t have an iPad) is excellent. They’ve thought well about the workflow of users and how they likely want to use the app. There are plenty of ways to find content, and you don’t have to download books to read chapters, etc.

Best of all? If you have questions, their support is super - they actually read your messages in a timely manner, and don’t give you a precanned response :)

Just keeps getting better and better.

The content has always been fantastic, but the app started off rather spartan... and got so much better with every iteration. User concerns like being able to search within books, being able to read table of contents without downloading, being able to control size of margins - all got addressed, and more.

Thank you for making this app better and better!
