excellent app, it gives me free access to company earnings calls and annual reports. I also love the convenience of calls being available offline so I can listen in whilst doing other things and even when internet or WiFi isn't available.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
