Trust is a very captivating idea. It offers both a product and app that work together seamlessly allowing users to view and manage their finances. The technological side of your idea works well, we shouldn't rule out over 50's using tech. As people get older, the familiarisation of technology like this will become the norm. I look forward to seeing a system like this on the market soon.
Your team has a very good idea. Letting people manage their finance with an app to see how far they are from a purchase/goal is very handy yo have. This service could potentially be used for not only for over 50's but for younger generations too. Having a visual representation of your finances makes life easier and it become a part of life.
The idea sounds interesting. It is good to gather some insight from your country and other countries that have an elderly population in a similar financial position. If you added a storyboard as to how the system would work will dramatically help push your idea. Great work.
