LearnHub.io lets you create your own self-learning pathways, basically a sequential list with learning resources for a subject. The main idea is; show what skills you’ve learned and how you learned them.
EQZEN lets you track multiple stock portfolios, cash savings, and other investments in a single view. Creating a portfolio does not require an account and it's not linked with your trading account, all your data can be saved (i.e. downloaded) to your device.
Browse financial data using your own API keys (IEX Cloud, YH Finance, Marketstack, etc.).
Currently works best with IEX Cloud (subscribed to separately), but working on adding additional data providers and other APIs (such as notifications, filings, news).
