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.
This is genuinely one of the cleanest and fastest finance apps out there to track the market.

Frequently asked questions
Professional Services
Aon is a British-American company headquartered in London, with the North American division working out of Chicago. It is a professional services firm providing risk management and consulting services across a wide range of different sectors, as well as data and analytics. The company operates on a global scale with roughly 50,000 employees working across over 100 countries. The name comes from the Gaelic word aon, which translates to one, and the shares of the company’s shares trade on the NYSE.
Born From a Merger
Aon was founded in Chicago in 1982 as the result of a merger between two different insurance companies. The two companies that formed what we today know as Aon, Ryan Insurance Group and Combined Insurance Company of America, did however have lineages tracing much further back than that. The company got its current name in 1987 and quickly built up a global presence through organic growth and several large acquisitions. The company also had a notable sponsor partnership with Manchester United between 2010 and 2015. Looking at a list of the competition gives us examples of similar companies such as Willis Towers Watson and Marsh & McLennan.
Services and Risk Capital
As previously mentioned, Aon provides a host of different services for its clients. These clients can be found in finance, hospitality, insurance, life sciences, logistics, and many other sectors. The company works in two primary divisions: Risk Capital and Human capital.
Within Risk Capital Aon provides, as suggested by the name, various types of risk management. This is done on a consultancy basis, helping companies as well as institutions in the public sector manage risk in various parts of their organizations and operations.
Human Capital
The Human Capital solutions provided by Aon are also incredibly diverse. The company provides services within analytics, health & benefits, workplace wellbeing, investments, and more. All of these combined services provided by Aon means that they can more or less be a one-stop shop for clients looking for consultancy services to help them address a wide array of different needs.
