DecisionTwin

DecisionTwin helps you understand your investment decisions — not just your portfolio. Every investment decision creates a path you take, and paths you don't. DecisionTwin lets you record your decisions, replay what happened afterward, and explore what might have happened if you had bought, held, or sold instead. Replay Your Decisions Watch your investment decisions unfold over time. Replay the journey from the day you made a decision to today, and see how the Buy, Hold, and Sell paths evolved side by side. Record Decisions from the Past Your investment history doesn't have to start today. Create a decision using a historical date and see how the different paths would have played out from that moment onward. Record Your Decisions Capture the important moments behind your investments. Record what you decided, your position, and the reasoning behind the decision. Explore What-If Scenarios See how different choices could have played out over time. Compare the path you took with the alternatives you considered. Track Your Positions Keep track of your holdings and see how your investment decisions affect your portfolio over time. Review Past Decisions Markets move on, but your decisions remain worth reviewing. Look back at previous decisions, replay their outcomes, and reflect on the thinking behind them. Focus on the Decision, Not Just the Result A good decision doesn't always produce a good outcome, and a bad outcome doesn't necessarily mean the decision was wrong. DecisionTwin is designed to help you review the process behind your investment decisions. DecisionTwin is a personal decision-tracking and reflection tool. It does not provide financial advice or recommendations. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
