DivTracker

DivTracker is an iOS app focused on tracking dividend-paying stocks and calculating your yield on cost across positions bought at different prices. You log each purchase with its date and price, then the app tracks dividends received and automatically computes what you're earning relative to what you originally paid. Over time, you see whether your dividend income is growing faster than the broader market and which positions are delivering the best income.

This works best for iPhone users building a income-focused portfolio who want to monitor their yield-on-cost without relying on spreadsheets. The app's portability means you can add a new position or log a received dividend on the go. If you're primarily a buy-and-hold investor and don't care much about tracking every dividend received, a simple spreadsheet or your brokerage's tools may be enough.
