01
Know your portfolio
Every position. Every broker account. One clear view of your exposure, cost basis, and performance.
A private investment portfolio tracker built for clarity.
Understand your investment portfolio.
Track investments across brokers and understand your holdings, FIFO cost basis, performance, exposure, and every decision behind them.
Built for investors who want clarity, not noise.
The real question
You know your balance. But do you understand your portfolio?
How much capital is actually invested?
Which stocks drive most of your gains or losses?
How concentrated is your portfolio?
Which broker account performs best?
Where did each buy and sell decision happen?
A clearer practice
Good investing starts with understanding.
02
Learn from your decisions
Every buy and sell tells a story. See transactions directly on the stock chart and review what happened.
03
Improve over time
The goal is not more trades. The goal is better decisions backed by clearer data.
