Show HN: OwnTime – a chess clock for your day's priorities

OwnTime is a time management app that functions like a chess clock for daily priorities, allowing users to set time budgets for specific tasks with only one timer running at a time and an alarm that sounds when a budget expires. Available on iPhone and Apple Watch (which sync together), the app prioritizes simplicity and privacy by storing all data locally without servers or accounts, and lets users export their full history as a SQLite database for custom analysis. Key features include Siri voice control, daily budget resets at midnight, and a focus on audible alarms rather than easy-to-miss notifications to interrupt focused work.
