Current version
BlendIQ 2.0.1 for macOS, iPhone and iPad has been available as a TestFlight build since 17 October 2026 – from the gas to the fill to the analysis of the dive:
- Gas selection: bottom, deco and stage gases for recreational, technical open circuit and CCR dives, always from common standard gases, checked against pO₂, MOD, END, gas density and isobaric counterdiffusion; gas volumes by rock bottom or the rule of thirds.
- Fill plan: partial pressure, premix and booster fills step by step with residual gas, storage cylinders, reserves, cooling intervals and cost.
- Fill sheet for the fill station: check off the steps, measure O₂ and He; print fill sheets, MOD labels and the price list via AirPrint or on a label printer.
- Operating limits at a glance, for CCR with setpoint scenarios.
- Dive analysis: import dives from Halcyon Symbios and Shearwater (more devices will follow) or as UDDF, with a traffic light for pO₂, END, gas density, ascent, stops, CNS/OTU and gas reserve.
- Guided introduction, three example dives, help in German and English, backup and restore including via iCloud.
A recommendation is a suggestion – the diver decides. BlendIQ does not replace training or a dive computer and is not a decompression planner; its calculation core uses established decompression algorithms (Bühlmann ZHL-16C with gradient factors). Always analyse and label the finished breathing gas yourself.
