Monthly tech roundup: the best products of April 2015

Thank you for reading this column. It’s a lot of fun to write, and inspiring to hear about how you use what I review. Or, how you’d rather it be hacked into oblivion. But I know that you can’t tune in every day. After all, isn’t that why we have DVRs and binge watching? You have homes to sell. This monthly summary of tech standouts is designed to help you catch up. We’re aiming to provide one every 30 days or so.
