Trimix Tools vs Dive Kit

Trimix blending and planning tools that can be used where you are and when you need them. You can use these tools to plan your mixes prior to arriving at the dive shop or to fill your cylinder at the air station or on the boat. Calculations are provided for the best Trimix given a planned depth and a desired maximum partial pressure of oxygen and equivalent narcotic depth (END). You can also calculate the ceiling and maximum depths along with your END based on your planned mix. The dive planning tools support both salt water and fresh water calculations. The blending tools provide for filling a cylinder with a remaining mix (or empty) to a specified target mix using oxygen, helium and a topping mix (air or another available mix). You can also calculate the result of topping an existing partially filled cylinder with a specific topping mix (air or another available mix). There is also a Bleed Down calculator that allows you adjust an existing full or partially full cylinder to a new mix with minimal wasted gas. Trimix Tools supports calculations in both metric and Imperial/US systems of measure. Traveling on a boat or working out of network range? These tools are at hand any time you have your iPhone, iPad or iPod touch. You could, for example, easily calculate the result of topping your cylinder from your first dive with air from the boat's compressor to take advantage of any remaining mix. You also have the convenience of saved settings that you can recall at a touch and adjust to a new situation as needed. Chances are you regularly work with a specific set of mixes and common dive situations. Trimix Tools includes the convenience of saved settings that you can recall and adjust to a new situation as needed. You can also select mix values using pre-installed default mixes or your own saved custom mixes. When updating one of the mixes for a tool you are offered a list of saved mixes that you can use directly or adjust as needed. You can save the currently displayed mix by tapping on the "+" button. Just like with the saved calculations, you can re-arrange or delete any mixes in your saved list. Do you need to share your planning or blending calculations with other divers? All the tools have the ability to share the results of the calculations from within the application. You can set default email addresses and a subject Trimix Tool's settings that will be automatically added when you share a result. All END calculations (Dive Planning and Best Trimix tabs) in Trimix Tools treat oxygen as a narcotic gas by default. There is an option available under the Settings tab to change the default so that oxygen is not treated as narcotic if that is your preference. Remember you must always personally analyze your mix before diving it. This application is not a substitute for proper training and should not be used as a substitute for proper dive planning or the primary Trimix blending and planning methods taught during training. Please do not attempt to handle high pressure oxygen or fill SCUBA cylinders without proper training.

A full deco planner in your pocket, and a free toolkit for the rest of the dive. Dive Kit plans open-circuit, trimix, and CCR dives with Bühlmann ZH-L16C and the gradient factors you choose. You see every assumption behind a schedule, and a share link reopens the exact plan on your buddy's phone or in any browser. Everything runs offline. The display stays readable in direct sun, the controls suit cold, wet hands, and routine tasks take seconds. DECO PLANNER (PREMIUM) The one tool you pay for. - Multi-level profiles with automatic gas switching and unlimited segments - CCR: depth-keyed setpoint schedules, diluent switches during deco, and a full open-circuit bailout from any point in the dive - Stop times to the second (MM'SS"), or rounded to the minute or 30 seconds; the table always matches the engine - PPO₂ caps per gas by O₂ content (lean, mid, rich bands), so each gas switches in where its PPO₂ allows - Contingencies: deeper, longer, lost gas, or build your own - Per-stop PPO₂, CNS% and OTU, gas density, and consumption per cylinder with reserve warnings - Oxygen breaks on long O₂ stops - Repetitive dives with tissue loading carried across the surface interval - Share by QR code or link; every setting travels with the plan - Export deco tables and printable slate images - Compare plan variants side by side with graph overlays ELEVEN FREE TOOLS No ads, nothing behind a sign-up. - Best Mix / MOD: nitrox and trimix, helium chosen by END, with oxygen-narcotic and density limits - Gas Analyzer: EAD, PPO₂, END, and gas density with color-coded warnings - Gas Usage: multi-level consumption, rule of thirds or sixths - SRMV / SAC: your real breathing rate from a logged dive, doubles and sidemount included - Buoyancy & Weight: weighting from suit, body, gear, and water type, with lift and overweighting advisories - Gas Blender: partial-pressure and continuous blending with real-gas corrections and expected analyzer readings - Checklists: build your own pre-dive routines, with timers that survive closing the app - Mix Result, Unit Converter, and more - Cylinders entered the way you name them: 80 cu ft at 3000 psi in imperial, litres in metric REFERENCE & LEARNING - 90+ illustrated, searchable dive signals - 35+ cylinder specifications from real manufacturer data - Tutorials on gas physics, decompression theory, and trimix - Tap any result for what it means and why it matters CERTIFICATION WALLET 25+ agencies, 190+ certifications, and a diver profile with insurance and emergency contacts. BUILT FOR THE BOAT - Fully offline, on phones and tablets - Exact decimal math in every gas number - Seven languages: English, German, Turkish, Swedish, Russian, Polish, Simplified Chinese - Light, dark, and automatic themes No ads. No account. Your dive data stays on your device, and the optional usage analytics can be switched off in Settings. Dive Kit helps you plan and check your numbers. It does not replace training, certification, or your own judgment in the water. Analyze your gas, dive within your limits, and plan conservatively. PRICING The Deco Planner is the only paid tool: a one-time lifetime purchase or a subscription. Everything else is free, for everyone. Built by a technical diver, shaped by recreational, trimix, and rebreather divers, and instructors.
