1. There is nothing wrong with the calculators themselves just there's not much information here unless you want to manually input it yourself, guessing if you could find these numbers you'd be looking right at fwd and trailing yield and payoutVery good app.
2. I suppose this would be helpful if you didn't have a calculator or one on your phone/computer, or the ability to look up these numbers on financial websites, and really wanted to do it manually inside an app.
3. Only downside is there is no option to add how mush you are adding to the investment on a weekly or monthly timeline.
4. A few calculators for yield, payout ratio etc.
