Atom Finance isn't an investing platform, but rather a hub that provides all of the information you need to track your investments and invest smarter. You can integrate your existing brokerage accounts and read up on the latest market commentary, analyst estimates, and event transcripts. You can also connect with other traders and have one-on-one or group discussions. All these features make it a great companion to any online brokerage, though you'll have to do the actual trading elsewhere.

The bulk of Atom Finance's third-party ratings come from its mobile app reviews. They are pretty positive, though some Android users have complained about it being a little slow. There doesn't appear to be a way to reach out to the company for support, but the apps are pretty easy to navigate and understand, so most people should be just fine.
