Rebreather checklists — KISS Sidewinder and Triton
Your unit in 3D, taken apart part by part, with the pre-dive build and post-dive care as steps that highlight what they are about. Cell millivolts, gas analysis and the scrubber ledger are kept. One app for the KISS Sidewinder, one for the Triton.
What KISS Sidewinder Companion does
The unit, in your hands, before you build it
An interactive three-dimensional KISS Sidewinder you can take apart. Every part tells you what it does and when it needs servicing, and the pre-dive and post-dive procedures walk you through step by step, highlighting the part each step is about. Your checklist runs and cell readings are saved.
- A 3D unit you can orbit, zoom and pull apart
- Ten-step pre-dive build and nine-step post-dive care
- Cell millivolts, gas analysis and scrubber ledger, kept
- Service intervals for every part, fully offline

What Triton mCCR Companion does
The same discipline, for the chest-mounted unit
The Triton built the same way as the Sidewinder app: a schematic-accurate 3D unit with the Kevlar bag, both counter-lungs, the horizontal axial scrubber, the removable cell chamber and the Monox display, plus the pre-dive build and post-dive care as steps that highlight the part they are about.
- The whole unit in 3D, part by part, with an explode slider
- Pre-dive build from Monox on to programming gases
- Cell linearity, gas analysis and leak-check logs, saved
- Service intervals for cells, valves, CMF orifice and hoses

Common questions
- Is there a pre-dive checklist app for the KISS Sidewinder?
- Yes. The KISS Sidewinder Companion runs a ten-step pre-dive build and a nine-step post-dive care routine, with the relevant part highlighted in 3D at each step. It is on the App Store and Google Play, and it works with no signal.
- Can I log oxygen cell millivolts and scrubber time?
- Both apps keep a persisted log of cell millivolts and scrubber duration, plot linearity error across the three cells, and track per-part service intervals so you can see a cell going off before it fails a dive.
- Does it cover the Triton mCCR too?
- The Triton mCCR Companion is the same idea for the Triton: a schematic-accurate 3D unit you can pull apart, step-by-step checklists, and the same cell and scrubber logging. It is in review and not downloadable yet.
- Do I need a signal to run a checklist?
- No. Both apps run entirely on the device, which is the point — the checklist you need on a boat is the one that opens with no reception.
