Q

Most money apps sell confidence: one number, one arrow. Q-Alpha is a learning app that shows you what you don't know. SCENARIO REVEAL Lock in your guess for an asset, then see 50 equally likely outcomes laid out as a distribution, with the 80% likely range spelled out. It is computed on your device from the price and volatility you choose, with no direction assumed — not a forecast, just the spread your own assumptions imply. Report what actually happened, and your calibration score shows whether your ranges ran too narrow: a quiet cure for overconfidence. RISK INDEX, SCORE BY SCORE See how five sub-scores — volatility, momentum, liquidity, trend strength and profitability — make up one 0–100 risk index. Use the built-in sample assets, or paste your own daily prices and volumes to get a risk index from your numbers. If an asset isn't supported, Q-Alpha says so instead of showing a made-up score. A SIGNAL THAT SHOWS ITS RULE The risk signal applies one published rule to the risk index and writes out its reasoning, so you can see exactly why it says what it says. It is not a forecast and never a buy or sell call. COMPARE AND BALANCE Overlay two assets on the same five-axis radar to see where their risks differ, and run a classical mean-variance allocation on the holdings you track to see how the weights shift. Every result shows its method and data source — an exercise, not a recommendation. QUANTUM ENGINE — A LEARNING DEMO Curious how quantum algorithms work? Run a small QAOA portfolio-selection example, compared side by side with the exact answer and a random baseline, plus a quantum-circuit sampling demo. Both run on a classical simulator: not a quantum computer, not hardware randomness, and never a forecast. PRICED TO LEARN Start free with the Risk Index — on sample data or your own — and up to 5 portfolio holdings. Pro unlocks Scenario Reveal, the risk signal, the Quantum Engine demo, side-by-side comparison, portfolio optimization and market scan, with up to 500 holdings, for $4.99/month or $29.99/year. One purchase covers iPhone, iPad and Mac. App Store category: Education. Q-Alpha is not investment advice, recommends no product and guarantees no return. Every output is a learning scenario; every decision is yours.
