I decided to give Pralana Online a try this weekend and signed up for a year's subscription. I like what I see so far after tinkering with it today. In January, I did the 14-day free trial of Boldin and decided to not pony up for a full year's subscription. I think I made the right choice with Pralana, albeit I'm saying this with only a short time with each product.
I don't think either product will radically change how I manage my finances. However, it's nice to have additional validation that my plan appears to be working and looks to be good for my duration on this earth (unless a doomsday of some sort happens).
Using all the default assumptions on returns and inflation, my "plan" seems to work with 100% confidence whether I die at age 90 or age 100. Over time, I'll build out a more detailed plan that is better tailored to my actual investment accounts.
I think it's $119 well spent. I'm not sure I'll pay the $89 for future years, but we will see.
