Flow Voice reads the options tape out loud so you never have to look away from the road. It watches live options flow and speaks only what matters, the big, size-worthy prints as they hit, so you can follow the tape completely hands-free. No charts to stare at, no feed to scroll. - Materiality gate: hear only prints above the premium threshold you set - Each new print spoken once, size and direction first - Session flips: know the moment sentiment turns bullish or bearish - Optional gamma alerts: spot crossing the call and put walls - Built for driving: one big broadcast button, a mute, and that's it No login and no account. Turn it on, set your ticker, and drive. QS Research is a market data and research reader for exchange-listed equity options (CBOE and other US exchanges). It provides no order placement, no trading of any kind, and no binary-options content. Auto-renewable subscription: payment is charged to your Apple ID at confirmation; it renews automatically unless canceled at least 24 hours before the end of the current period, and you can manage or cancel it in your App Store account settings.
