Abysner vs DiveHub

Abysner is an open-source, modern dive planning tool with a focus on simplicity and usability. Built to give something back to the diving community, its primary aim is not to be the most feature-rich, but to be quick, user-friendly, and straightforward. Whether you're planning a deep technical dive or just want to check your MOD, Abysner makes dive planning smooth, accurate, and fast—perfect for use even right beside the water. Supported Features: • Models: Supports Buhlmann ZHL-16 A, B, and C with gradient factors. • Multi-Gas Support: Plan dives with Air, Nitrox, Oxygen, Trimix, Helitrox, Heliox, and more. • Oxygen: Includes OTU and CNS tracking for safe dive planning. • Customizable Settings: • Set salinity and altitude according to the diving environment. • Adjust SAC rates, ascent/descent rates. • Fine-tune decompression stop intervals and last deco stop depth. • Control max PPO2 for both during deco stops and normal diving. • Gas Picker: An intuitive interface for selecting and managing gas mixes, with critical information at your fingertips. • Automatic Contingency Plans: Automatically adjusts for longer or deeper dives, with configurable extra time and depth. • Gas Planning: • Visual chart of gas requirements per mix. • Density and PPO2 info at maximum depths for each gas. • Multi-Level Dive Planning: Plan dives across different depths with ease. Please note: CCR planning is not available yet. More coming soon!

EDUCATIONAL PURPOSE ONLY - NOT FOR REAL DIVE PLANNING DiveHub is a fan project created to help divers learn and understand decompression theory. This app implements the Bühlmann ZH-L16C algorithm with gradient factors, but lacks many features required for safe, real-world dive planning. Key Features: • Bühlmann ZH-L16C Decompression Algorithm • Gradient Factor support (customizable GF Low/High) • Open Circuit (OC) multi-gas planning • Closed Circuit Rebreather (CCR) support with bailout planning • Multiple decompression gases • Real-time dive profile visualization • Equivalent Narcotic Depth (END) calculations • Gas density monitoring with safety thresholds • Time To Surface (TTS) calculations • Customizable ascent/descent rates • Altitude diving support with custom surface pressure • Fresh water and salt water density options • Save and manage multiple dive plans • Some level of Gas Planning • BLE Nitrox Analyzer Not included features: • Complete Gas planning feature • ICBD warning, HPNS warning • etc. Technical Diving Concepts: Learn about decompression stops, tissue compartment loading, gas switching protocols, ppO2 limits, Maximum Operating Depth (MOD), CNS oxygen toxicity tracking, and CCR bailout planning. Important Safety Notice: This app is for educational purposes only. It does not account for all physiological factors, environmental conditions, or emergency scenarios. You must be properly trained in decompression theory and dive planning. Only dive within your certified training level. All dives carry risk of Decompression Sickness (DCS), which can cause serious injury or death. The developers are not responsible for any injuries or incidents resulting from using this application. You assume all risks associated with diving. Requirements: • Full understanding of diving terms and decompression theory • Proper dive training and certification • Use alongside professional dive computers and planning tools
