About this app

Still Dive supports your freediving training: time your breath-holds, track your progress, create O₂ and CO₂ tables, practice dynamic apnea exercises, and work on your breathing, all in one simple app.

STATIC FREEDIVING TIMER
• One large button, a timer accurate to a tenth of a second.

Each time is automatically recorded, and your best time is always displayed.

HISTORY AND PROGRESSION
• A graph of your breath-holds over 7 days, 30 days, 3 months, 1 year, your entire history, or any number of days you choose.

Best time, average, and number of breath-holds at a glance.

• The same history for your tables, breathing exercises, and dynamic apnea sessions.

Your personal records and badges, all in one dedicated tab.

SHARING CARDS
• After a result or record, create a personalized card: time, date, and a background photo chosen from 18 options.
• Share it with the app of your choice. Nothing is sent without your consent.

OCD AND COD TABLES
• Generated from your best time, or a reference time you set.

OCD: constant rest, progressively longer breath-holds. COD: constant breath-holds, progressively shorter rests.

• Number of sets, percentages, and rest times are fully adjustable, with ready-to-use default values. The settings remain collapsed until needed, with the total session time displayed at a glance.

• A bar graph shows the table at a glance: the current set is highlighted, and the remaining time is displayed during the session. • Audible beeps, vibrations, and voice prompts, each customizable to your liking.

SQUARE AND RECTANGLE BREATHING
• Four counts: inhale, hold lungs full, exhale, hold lungs empty.

• Square: all four counts are equal, with a single duration setting.

• Rectangle: inhalation and exhalation of a set duration, breath holds approximately 1.4 times longer (e.g., 4-6-4-6). Change one, and the other adjusts.

• An inflating and deflating sphere gently guides you (or, if you prefer, the outline of the frame), with a distinct beep and vibration for each count.

• A set number of cycles, or an endless session that you can stop whenever you want.

DYNAMIC APENED: SQUATS AND WALKING
• Squats: two sets of consecutive squats while holding your breath, with a beep every 3 seconds. The counter advances with each beep, and you can adjust the number before completing the set.

• Walking: three breath-holds while walking.

• A "Relax and Breathe" screen appears before each repetition, followed by a rest period (2 minutes by default, adjustable) between them.

DESIGNED TO BE USED, NOT MONITORED
• The session continues with the screen off or the app running in the background, with a notification indicating the remaining time and a Stop button.

• The screen remains on during sessions.

Only one session at a time, to avoid confusion.

YOUR DATA STAYS ON YOUR HOME
• No account creation or registration required.

Everything is saved solely on your phone. The app doesn't even have internet access.

French and English are available, selectable in the settings or according to your phone's language.

SAFETY
Still Dive is a timing and training tool, not a medical device. Freediving involves risks: never practice it alone, or in the water without a trained safety buddy. Tables are used on dry land. Never practice breathing exercises while driving or in the water, never do squats or underwater walking alone or near water, and stop immediately if you feel dizzy or unwell.

This version is currently under development: your feedback is welcome.
