Thank you for your comment.
No, it unfortunately does not perform income calculations as of now. But thank you for your feedback, it would absolutely be a good complement to the dividend tracker functionality. It really took its time to structure all dividend payer companies, I surely add your feedback to the backlog as well.
May be worth to mention as a side note..
It is possible to add any stock (or ETF) to your watch list within the app.
In the Stock Screener section of the app, it is also possible to short list stocks. Example: You can filter stocks that have a dividend yield > 2%, and have an ex-dividend date that is within the next 1 month.
