An app I’m helping design and build that turns the most common investing regret — “I wish I’d bought earlier” — into a hands-on lesson anyone can run in seconds.
The "What If" App
What if you'dinvested back then?
Theconcept
Pick a company or fund, a date, and an amount. The app instantly shows what that investment would be worth today, plotted against what you’d have earned in a savings account or the S&P 500. It makes the cost of waiting — and the power of compounding — impossible to ignore.
MyContribution
I’m working on the product concept and the coding side — designing the “what-if” calculation, wiring up historical price data, and shaping an interface that a first-time investor can actually understand.

I’m writing about the process — the product decisions, the bugs, and what building a finance tool teaches you about finance itself.
Screenshots
Real product screenshots will replace the mockup once the beta build is ready.
