About Corner Timer: Boxing
Corner Timer is a focused round timer that helps boxers stay with the rhythm of each session and concentrate on movement and breathing. Train at your level, from beginners learning the fundamentals to experienced boxers building demanding routines. Keep your favorite music playing and move with a ring timer that signals every round. Adjust the session and its five-level intensity rating to match your condition, then review your training history and progress graphs at a glance. Large controls remain practical with gloves or sweaty hands. Oversized numbers make the time and current round readable when an iPhone or iPad is placed across the gym. Red identifies training, blue identifies rest, and a high-contrast pause state keeps every phase clear. Key features - Create and edit presets with up to 15 rounds - Set round, rest, preparation, and optional warning times - Keep external music playing and request system-controlled ducking for bells - Classic, double, and digital boxing bells with 1% volume adjustment - Lock Screen Live Activity and background bell alerts - Large portrait and landscape timer layouts for iPhone and iPad - On-device workout history, notes, and a five-level intensity slider - Read-only workout details, monthly progress graphs, and shareable 9:16 results - Private iCloud sync between supported devices using the same Apple Account - Premium weekly plans, round-by-round guidance, and progress reports No account, advertising, analytics, or tracking is included.
