Every (?) behind a calculated figure now shows its formula: what goes in, where each value comes from, and how it is rounded. SCR, surface consumption rate, replaces SAC throughout, and the second level is now the second deep segment. A second deep segment is offered only at depths the plan can use: the depth track runs between them, and a pick lands on the nearest one that plans. CNS: a bottom minute above 1.2 bar counts at its table row where that is stricter, and each deep segment at its own ppO2. At large text sizes, each (?) opens as a sheet you can scroll.

The shared picture ends with the App Store link and a QR code for a buddy, beside the app's icon, and the share sheet opens with the picture on the first tap. Every boundary on the runtime ladder, and the total dive duration, round to the nearest minute — a 1.1-minute move prints 1, not 2 — and the swim from 6 m at 1 m/min prints its six minutes. The minimum gas (?) states the rule and its assumption: C × A × T — two divers on one supply, never below 2 × 20 L/min; the mean of the pressures at the level and at the switch; the ascent at 3 m/min plus a minute for the problem and a minute for the switch. More apps by the author, from Settings.

The decompression is cleared at 6 m: the long stop is there, and the slow swim to the surface comes after it. Descent 20 m/min by default. Deco time counts from the gas switch to leaving 6 m. The back gas fill is the bottom phase plus the minimum gas, every pressure on the ten-bar grid, and the wetnote schedule is a three-column table. In pragmatic mode the 6 m stop is at least the 21–9 m stops added together. Bottom time counts from the surface by default, as your team and DecoPlanner count it — untick "Descent inside" to set minutes at max depth instead. Gradient factors per plan: 20/85, 30/70, 40/85 or your own pair, saved with the plan. The runtime ladder reads depth, duration, runtime, says once how a stop is held and where to slow to 3 m/min. The Plan card is four figures under the total dive duration. The gas plan says what you leave the bottom with and switch on, and about how many bar every 5 minutes at depth. On-the-fly adjustments: what +5 or −5 minutes at the bottom, or 3 m deeper or shallower, add in deco and cost in gas — re-planned, not a rule of thumb. View details opens the whole plan on one page, and that page is what you share as a picture. The bottom gas row shows air, 21/35 and 18/45 with the rest behind More gases; a locked time slider says why. Two-level dive profiles. A dive no longer has to be square: add a second level on the Dive card — any depth, any time, shallower or deeper than the first — and the deco is solved for the whole profile. The plan prints both levels, the minimum gas from each, what you leave each level holding, and the turn pressure names the level it falls in. The wetnote carries both rows.

The store listing now says what the app is in the words divers search for. Nothing in the app changed: every schedule, gas figure and limit is what 1.3 printed.

A new look: a photograph at the top, an icon on every section, the runtime and the four legs as tiles, and the plan in three cards — the figures, the profile with the schedule under it, and the gas plan. Share as image sends the whole plan as one picture: runtime, legs, CNS, the profile, the schedule and both fills. Nothing in the planning changed: every schedule, gas figure and limit is what 1.2 printed.

Settings has a Rate Time to Surface row under Feedback, and the app asks once — after the second plan you save — whether you would rate it. Nothing in the planning changed: every schedule, gas figure and limit is what 1.1 printed.

Saved plans and repetitive dives. Build a dive, keep it under a name, and reuse it. Then say that up to three saved dives came before the one you are planning, each with the surface interval before it. Every earlier dive is re-solved in full — descent, time at depth, every stop and the last six metres — and off-gassed through the interval on air, nitrogen and helium both. No published table covers repetitive decompression dives; this is the model run forward, and the app says so. A wider envelope. 15 m to 56 m. 51 m is still the stated limit and the app says so past it — deeper than that the binding constraint is gas density, not oxygen. Six bottom gases: EAN32, triox 30/30, EAN28, air, 21/35 and 18/45. And the deco bottle is yours to choose — AL80, AL50 or AL40. Which one fits depends on the deco gas rather than the depth: oxygen is breathed only from 6 m, so the same bottle buys about twice the bottom time. Pragmatic decompression, off by default. Linearises the stops between 21 m and 9 m the way the course material teaches, then re-solves the last stop from the modified tissue state. It is a simpler profile to fly, not a safer one, and the app does not claim otherwise. A plan screen with one control per number. Depth, bottom time and both cylinder fills are sliders with the standard values as ticks you can tap. The bottom gas is six chips, all of them on screen. The fill control says what it will do rather than asking you to work out a checkbox, and imperial divers get feet on the depth slider instead of converted metres. Also: bottom time is minutes at maximum depth, with the descent as its own named leg. The oxygen clock counts the last six metres and carries forward between dives at a 90-minute half-time. The longest bottom time offered is worked out from your gas, cylinders and settings rather than a flat hour. And on a long oxygen run, a line says when a break on back gas is due.
