*** NEW IN VERSION 2.0 *** • CROSS-PLATFORM EXPERIENCE PATimer is now available on iOS! Download once and use it on both your Mac and iPhone. Your trading companion is now with you wherever you go. • PRE-MARKET COUNTDOWN Success favors the prepared. The new Pre-Market Countdown starts 30 minutes before the official market open, giving you the perfect window to analyze news, check pre-market movers, and get in the zone. • LIVE ACTIVITIES (iOS) Track the market open directly from your Lock Screen or Dynamic Island without even opening the app. --------------------------------- PATimer is a professional countdown and focus tool specifically designed for traders who follow Price Action trading principles. Now available on both macOS and iOS. Instead of continuously watching the market or making impulsive decisions, PATimer helps traders build a fixed observation and decision-making rhythm. Users can set a recurring countdown cycle (e.g., every 5 minutes). During each period, the app provides sound alerts to signal key time points—like the closing seconds of a candle—reminding users to pause, reassess the market, and act with discipline. This approach is invaluable for intraday trading, where emotional control and timing discipline are critical. KEY FEATURES: - Cross-Platform: Seamless experience on Mac, iPhone, and iPad. - Pre-Market Mode: A dedicated countdown to the US market Open. - Recurring Timer: Customizable intervals (e.g., 5 min, 15 min, 1 hour). - Sound Alerts: Audio cues specifically designed for traders (e.g., a "Tick-Tock" sound in the final seconds). - Private & Secure: Runs entirely locally with no account or login required. - Visual Focus: Clean, distraction-free design optimized for trading desks. PATimer does not provide trading signals, investment advice, or market analysis. It is purely a Time Management and Discipline tool designed to support structured decision-making. Whether you are a Price Action trader or someone who needs a structured time-based focus tool, PATimer helps you stay calm, focused, and consistent.

Verdict
The clearest difference is iOS requirement: BookConvert at 14.0 against PATimer Pro's 17.0. On price, ads, in-app purchases and device support there is nothing between them.
