Saved me from writing an app

I regularly depend on weighted decision matrices to navigate my life. I started thinking about how an app that does this would look like. Lo and behold, The Lost Project has created one already, and it’s perfect. The only thing I can say is in my own matrices, I use a 1–5 scale instead of 1–9 for evaluating options. I suppose it doesn’t make a huge difference, but it could be a nice feature to add.

Really neat app

It helps to structure your thoughts and things to consider to help you weigh pros and cons. Then based on the results you can easily which options are best for you. It’s a much cooler way to write a pros and cons list. It even shows a graph to make seeing it easier.

Exactly what I wanted

Many times over the years I’ve used a Weighted Decision Matrix to help me select from multiple choices. Examples include deciding which car to buy and where to go on vacation. This app is perfect for these tasks.
