Worth it!
I have bought a couple of apps from this guy and really like the attention to detail in his apps: they are elegant and well-executed. Some issues with third-party data but he is working on it and is prompt to respond.
I look forward to an HP 17 and 19 BII version; some more menus to include the venture capital method, Private equity related equations, and multiple step (5) ROE would be just the start of my wishlist!
I fully support his efforts and if I can squeeze in another request: a valuation app!
UPDATE: need solver! Maybe time for a 17/19B II version?
