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

OwnTime is a time management app for iPhone and Apple Watch that applies the concept of a chess clock to your daily priorities. You set daily time budgets for each priority, and only one clock runs at a time—starting one pauses the rest. When a budget is spent, a real alarm goes off, even through Focus and silent mode, ensuring you're pulled out of deep work. The app works standalone on either device, syncs directly between them, and offers Siri and Shortcuts integration for hands-free control. Privacy is paramount: no server, no account, and your data lives in a plain SQLite file that you can export and analyze with your own tools. OwnTime is a one-time purchase on the App Store, requiring iOS 26.1 or watchOS 26.
When a budget is spent, a real alarm goes off, through Focus and silent mode. That is the whole point: it kicks you out of what you are doing when its time is up.
