No ads, no account, and no internet connection. Big Text Note shows one note in large, easy-to-read text so you can hold it up to the person in front of you. It works as a simple communication board: for talking with someone who is deaf or hard of hearing, for the days when your own voice is not available, for noisy places like stations and event halls, or for a quick word at a counter or reception desk. Type it, show it, and if needed, let the device say it. Read Aloud speaks the note with the voices built into your iPhone or iPad. The language is detected from the text, and nothing is sent to a server. Voice input turns what the other person says into text on the device. You choose whether to append the result to the note or replace it. Audio is never saved; only the text you keep is stored. Show mode turns the note into a clear message board. Pick Normal, Large, or Huge, fine-tune the size, and choose text and background colors, including high-contrast pairs. Flip the note upside down for the person across the table, or turn your iPhone sideways for one long line. The screen stays on while Show mode is open. Quick Phrases keeps four ready-made lines and up to 20 of your own, one tap away. Reorder your phrases whenever you like. Add the Home Screen widget to keep the current note in view. No account, no ads, no tracking, and no server sync. The note stays on your device. Write to talk, flip for the person across, or open straight from the Lock Screen and Control Center.

Executive OS is a private AI Chief of Staff that runs sealed inside your phone. No cloud. No analytics. No remote backend. Every founder, CEO, and high-net-worth operator faces the same cognitive load: too many decisions, too little structured reasoning, too much data leaking into other people's servers. Executive OS solves this by putting your private operating system on a single device, encrypted with AES-GCM 256, sealed by your biometric. CHOOSE YOUR TERM Monthly $19.99 · Yearly $49.99 · Lifetime $99.99 one-time. Everyone who purchased Executive OS while it was a paid app keeps permanent access at no cost — forever.

Listen in a luxury synthesized voice. WEALTH OPERATING SYSTEM Track net worth across real estate, cash, investments, equity, vehicles — in six currencies. AI Wealth Analyst flags concentration and liquidity gaps. CALIBRATION — JUDGMENT YOU CAN MEASURE State your own confidence on every call. Months later, record what actually happened. Executive OS scores you with a Brier score, plots your calibration curve, and splits it by domain — so you learn where your judgment holds and where it does not. Before you commit to a number, it shows you what happened the last times you felt exactly this certain. EXECUTIVE SEARCH One field across every decision, task, retrospective, holding and playbook. Entirely on device. Vault secrets are never indexed. DECISION ENGINE WITH COACH MODE Strategic questions answered with structured reasoning, risk-reward framing, confidence scoring.
