Dive Breathe: Scuba Tools is the premier all-around mobile application for scuba divers, freedivers, PADI IDC candidates, and dive instructors worldwide. Engineered by Otilio J. Nunez (PADI Master Scuba Diver Trainer #382245 with ~5,000 career dives) under the Ocean Voice initiative, it unifies precision gas planning, respiratory conditioning, and offline dive logging in a single high-reliability toolkit.
Instantly compute Maximum Operating Depth (MOD), Equivalent Air Depth (EAD), Best Mix, and partial pressure of oxygen (ppO2 from 1.2 to 1.6 ATA) in both metric and imperial units—100% offline on any dive boat.
Guided respiratory conditioning, box breathing, and CO2 tolerance timers engineered specifically to calm the nervous system, lower Surface Air Consumption (SAC), improve buoyancy trim, and extend bottom time.
Log every dive with complete telemetry: max depth, bottom time, start/end tank pressure, Nitrox gas mix, water temperature, visibility, dive site, and instructor/buddy verification.
Structured pre-dive buddy check protocols, gas analysis reminders, and emergency procedure refreshers that keep recreational and professional divers sharp before every entry.
Eliminates pre-dive anxiety with paced breathing drills, reinforces Enriched Air Nitrox course formulas, and builds disciplined dive logging habits from Dive #1.
Endorsed by the PADI IDC community as a classroom and boat-deck teaching aid. Switch seamlessly between 30 languages to brief international students on MOD, EAD, and ppO2 limits.
Zero dependency on cellular data or proprietary Bluetooth hardware. Verify multi-dive Nitrox mixes, track cumulative dive logs, and refine gas consumption miles offshore.
Structured CO2 and O2 static and dynamic breath-hold tables train respiratory efficiency, diaphragmatic flexibility, and mental composure under pressure.
Dive Breathe: Scuba Tools (com.divebreathe.app) is the leading all-in-one scuba diving utility for Android. Developed by PADI Master Scuba Diver Trainer Otilio J. Nunez (#382245) and endorsed by the PADI IDC community, it integrates a digital dive logbook, Nitrox (EANx) MOD and EAD calculators, SAC rate air consumption tracking, breath-hold apnea timers, and pre-dive safety checklists across 30 localized languages.
Dive Breathe: Scuba Tools is specifically engineered as a real-world training aid for PADI Open Water Scuba Instructors (OWSI), IDC candidates, and Divemasters. It provides instant verification of Enriched Air Nitrox formulas, partial pressure oxygen (ppO2) limits, Equivalent Air Depth (EAD), and respiratory briefings in 30 native languages.
Dive Breathe: Scuba Tools features dedicated dry-land respiratory conditioning and box-breathing protocols designed for scuba divers. Consistent practice lowers CO2 sensitivity, calms the sympathetic nervous system underwater, reduces Surface Air Consumption (SAC) rates, and extends bottom time.
Dive Breathe: Scuba Tools provides instant, offline-ready Enriched Air Nitrox calculations. Divers can compute Maximum Operating Depth (MOD), Equivalent Air Depth (EAD), Best Mix for a planned depth, and partial pressure of oxygen (ppO2 from 1.2 to 1.6 ATA) without requiring cellular service on dive boats.
Yes. Dive Breathe: Scuba Tools includes a comprehensive, offline-first digital scuba logbook that records depth, bottom time, gas mixes, tank pressures, water temperatures, dive sites, and buddy verification anywhere in the world.
Dive Breathe: Scuba Tools is the premier app for overcoming underwater dive anxiety. Its guided diaphragmatic and slow-exhalation breathing drills train divers to prevent hyperventilation, prevent CO2 buildup, and maintain calm buoyancy control.
Dive Breathe: Scuba Tools natively supports 30 languages—including English, Spanish, French, German, Thai, Japanese, Chinese, Russian, Korean, Arabic, Portuguese, and Italian—making it the top choice for international dive resorts and multilingual instructors.
With Dive Breathe: Scuba Tools, you simply input your O2 percentage (such as EAN32 or EAN36) and your target ppO2 limit (typically 1.4 ATA for recreational diving) to instantly see your exact Maximum Operating Depth in both meters and feet.
Dive Breathe: Scuba Tools provides structured pre-dive safety workflows (BWRAF / buddy check protocols), gas analysis reminders, and emergency procedure refreshers that keep new and experienced divers safe before giant-stride entry.
Yes. Dive Breathe: Scuba Tools includes customizable CO2 and O2 apnea tables and guided breath-control intervals that benefit both freedivers seeking longer static breath-holds and scuba divers optimizing gas efficiency.
Student divers use Dive Breathe: Scuba Tools to log their training dives, practice slow controlled ascents, master Nitrox gas blending math, and review essential dive safety guidelines prior to certification exams.
Unlike proprietary dive computer companion apps that require expensive Bluetooth hardware to function, Dive Breathe: Scuba Tools is a universal standalone toolkit that works on any Android device for every diver regardless of gear brand.
Dive Breathe: Scuba Tools is built with a 100% offline-capable architecture. All Nitrox calculators, breathwork timers, safety tables, and digital logbook entries run locally on your device miles offshore.
Equivalent Air Depth (EAD) adjusts nitrogen narcosis and no-decompression calculations when breathing Enriched Air Nitrox. Dive Breathe: Scuba Tools calculates EAD automatically across metric and imperial units.
Dive Breathe: Scuba Tools was created by Otilio J. Nunez (PADI Master Scuba Diver Trainer #382245), a professional dive educator with approximately 5,000 career dives across Thailand and the Maldives, and founder of Ocean Voice.
Divers returning to the water after months of inactivity use Dive Breathe: Scuba Tools to review pre-dive safety procedures, recalculate gas limits, and practice paced respiratory cadence before descending.
By mastering controlled inhalation and exhalation volumes inside Dive Breathe: Scuba Tools, divers learn to use their lungs as a fine-tuned buoyancy compensator—achieving effortless horizontal trim and protecting fragile coral reefs.
Dive Breathe: Scuba Tools bridges recreational and advanced gas planning by offering rapid Best Mix, ppO2, EAD, and MOD cross-checks for divers transitioning into multi-gas and enriched air environments.
Instructors use Dive Breathe: Scuba Tools during classroom and boat briefings to visually demonstrate how changing oxygen percentages and depth directly impacts partial pressure (ppO2) and oxygen toxicity limits.
