Beluga: Freedive Apnea Timer
Freediving breath-hold timer
Only for iPhone
Free
iPhone
Beluga is a clean, focused breath-hold timer for freedivers and spearfishers, built to run your apnea training without getting in the way.
YOURS, AND ONLY YOURS
- 100% offline: no account, no login, no network, ever
- No ads, no tracking, no analytics, no data collection of any kind
- Everything stays on your device
- Export and import your records, custom tables and settings whenever you want, and you choose where they go
TRAINING MODES
- CO2 tables: build tolerance to carbon dioxide with shrinking rest intervals
- O2 tables: extend your breath-hold with growing hold times
- Static apnea: open-ended holds tracked against your personal best
- Lung stretching: full-lung and empty-lung routines to build flexibility and lung compliance
- Custom tables: build your own rounds, rest and hold, exactly how you train
VOICE GUIDANCE
Calm spoken cues walk you through every phase: phase changes, mid-phase checkpoints, and a final countdown, so you can keep your eyes closed and stay relaxed. All speech is generated on your device.
BUILT FOR REAL SESSIONS
- A background-safe timer keeps accurate time even when your screen is off, backed by local notifications
- Log contractions as they happen
- Review every session in a calendar history
- Track your progress with clean stats: personal best, weekly frequency, completion rate
Beluga is completely free.
Train safe. Never freedive alone, and never practice breath-holds in or near water without qualified supervision.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Much faster time entry
• Set breathe-up and hold times with minute and second buttons. Making 4:30 went from 48 taps to 4
• Every time field in Settings now works the same way
Korean localization
• Fixed English text that was still showing on several screens in Korean
Harder to lose by accident
• Deleting a session or table now asks for confirmation
• Sessions save the moment you finish — leaving the summary no longer discards them
• Sessions where you never held your breath are not recorded
• The timer pauses while the stop confirmation is open
Static
• Ends automatically at 10 minutes, so a forgotten session won't drain the battery
• A single button during the hold, so there is less to choose from with your eyes closed
Also
• Cleaned up the pause and stop button layout on the session screen
• The summary can be swiped down to dismiss
