Fundamental: Investing Journal

See your principles, not the price. Most investing apps put returns and a ticking price on the first screen. The number lifts you when it rises and rattles you when it falls — and pushes you into impulse trades. Fundamental does the opposite. It doesn't show price or returns at all. In their place it keeps the reason you bought — the principles you set at purchase. When you're anxious, what you see isn't "how far it dropped" but "is my reason for buying still true?" ■ How you use it · Set buy principles: write, in your own words, why you'll keep holding. · A calm home: no balances, no returns — just your principles, kept. · Check: when anxious, weigh your principles one by one instead of the price. · Reappraise: when a principle is shaken, look back at the calmer past you, then decide for yourself to hold, revise, or sell — and record it. The app never sells for you. · Journal & retrospect: your decisions and their reasons build up, reflecting what kind of investor you are. ■ What it doesn't do · No quantities, no average cost, no returns. · Your records stay on this device only. No account linking, no sign-up. · No scores. Fundamental is a mirror, not a judge. Your principles are a seatbelt the calmer past you fastens for the shaken you now. In rough seas, drop the anchor of your principles.
