Hey, I really like the app and have signed up. One thing I would add is multi- family units. Even better would be the concept of "house hacking" or buying a multi-family and moving into one of the units. This may just be a US thing, but this allows you to have a low down payment and cash flow and live for free. This is a pretty popular thing to do in the US, and I haven't seen any tools that account for it. I am currently doing this and use excel for all my calculations. Also, maybe add a remodel calculator, I. E. If I do a remodel for 10,000 and the rent goes up by 500 my yoy roi is like 60%. This number goes up even more of you get a loan and use leverage.
