Review your schedule.
Plan on Buhlmann ZHL-16C with gradient factors, on the Thalmann exponential-linear algorithm in seven parameter sets, or on DiveLogic's hybrid of the two. Run one dive through each and read the schedules side by side.
Tissue compartments, ceilings, model divergence and the raw schedule are one step away.

Catch the risks.
Gas density at depth, isobaric counterdiffusion on a helium switch, ppO₂ against your limits, ascent rates, scrubber life. Warnings are specific, and when limits disagree the conservative number wins.

Real engine output. The first line is the 45 m air plan above flagging its own gas density; the rest come from a deliberately aggressive test plan.
Blend your gas.
Partial-pressure blending that starts from what is already in the tank, decants from your real supply cylinders and says whether they can deliver the mix. Best mix, MOD, END and density come from the same engine as the planner.
On a rebreather: setpoints, diluents, scrubber life, and a bailout schedule from every level of the dive.
- 116bar
Add 96 bar of oxygen. Tank pressure → 116 bar
Decant from the 50 L bank at 200 bar; it ends at 179 bar.
- 200bar
Fill with air to 200 bar. Add 84 bar
Sync your computer.
Pair a Shearwater Perdix, Petrel or Teric over Bluetooth from the desktop app and read the dives it holds. No cables, no export files.
Profile, gases, events and dive mode come across as the computer recorded them, ready to log and review.

Example review. For education and reflection, not a diagnosis.
Review the dive.
DiveLogic lays the recorded dive over the plan and scores adherence out of 100 from named measurements: depth deviation, descent delay, ascent rate, short stops.
A symptom questionnaire covers what the computer cannot record. The evidence-based review weighs both and states its findings plainly.
Also in every account.
Ask the assistants
AI planning and blending assistants running on the same engine as every other screen. They draft; you check.
Plan as a team
Share a plan with your dive team. Each diver carries their own gas and conservatism, marks themselves ready, and gets the printable report.
