Apps

Small tools, built with care

Native apps for Apple platforms. No accounts, no tracking, no analytics. Everything runs on your device.

Homing

Reconnect Earbuds · macOS

Your AirPods hop between devices. Homing brings them back to your Mac with one click in the menu bar or a global shortcut, and can switch audio output and microphone to them as soon as they connect.

BlendIQ – GasBlender

Gas selection, fill planning & dive analysis · macOS · iPhone · iPad

From the gas to the fill to the analysis of the dive. Recommends bottom, deco and stage gases for recreational, technical open-circuit and CCR dives from common standard gases, checked against pO₂, MOD, END, gas density and isobaric counterdiffusion. Plans partial-pressure, premix and booster fills step by step with residual gas, storage cylinders and fill cost, and prints fill sheets, MOD labels and price lists via AirPrint or on a label printer. Imports dives from Halcyon Symbios and Shearwater (more devices will follow) or as UDDF and checks them with a clear traffic light. Not a decompression planner; its calculation core uses Bühlmann ZHL-16C with gradient factors. It does not replace training or a dive computer — always analyse and label the finished gas yourself.

DiveIQ – Logbook

Dive logbook & analysis · iPhone · iPad · macOS

The logbook for recreational and technical divers. Brings your whole log along from Diving Log, UDDF and other logbooks, reads dive computers via Bluetooth, takes over many dives at once from a Shearwater Cloud export and imports Apple Watch Ultra dives from Apple Health. Dive sites with map and sketch, trips, buddies, certifications and equipment; analysis of how you dived, statistics and no-fly time. Opens dives in BlendIQ with one tap. Works offline, your data stays on your devices and in your iCloud. It does not replace training or a dive computer.

DecoIQ – Decoplanner

Decompression planning · iPhone · iPad · macOS

Plans open-circuit and CCR dives with gradient factors: profile, gases and runtime, with bailout and “what if” at every point of the dive. Change any parameter without starting over, compare GF sets, plan repetitive dives and check whether a longer stay still works out. Plans from wreck and cave sketches, runtimes in familiar formats, and hand-over to BlendIQ and DiveIQ. A planning tool — it does not replace training or a dive computer.

CVE-Agent

Prioritize CVE risks locally · macOS

Brings public vulnerability data from NVD, CISA KEV, FIRST EPSS, CVE List V5 and – new in 1.16 – CERT-Bund (BSI) advisories together in one local Mac app. Filter by your vendor portfolio, see CVSS, EPSS, KEV and CERT-Bund signals side by side, and let the optional hourly background check notify you about new critical findings. Reports and configuration stay on your Mac. Version 1.16 brings the Liquid Glass interface for macOS 26/27 with a system menu in the menu bar.

MultihomingGuard

LAN first, Wi-Fi as fallback · macOS

Docked Macs keep Wi-Fi and Ethernet up at once and traffic takes whichever path it pleases. A root daemon verifies the wired path – link, IPv4/IPv6 with gateway and a DNS answer over that adapter – before it takes Wi-Fi out of the picture, and brings it back within a second when the cable goes. "Wi-Fi off" removes the address, not the radio, so Apple Watch unlock, AirDrop and Handoff keep working. iPhone USB tethering counts as wired. In day-to-day use the app never asks for a password; a hidden admin mode pauses the guard, and macOS itself asks for administrator credentials for that. While a VPN tunnel is up the menu says so, whatever the vendor, and an optional guard stops a cable device from shadowing the company DNS. With nothing connected at all it reports offline instead of claiming Wi-Fi. Updates itself from a signed manifest with one click. Ships as a signed, notarized pkg you install yourself. English and German. Nothing leaves the Mac.
