Divers know that what matters lies beneath. We build software the same way: calm on the outside, precise underneath. From a focused app on your phone to a platform your whole organisation runs on — designed, engineered and looked after in Austria.
01 · Apple
Native apps that feel at home on every Apple device — fast, accessible and built with Swift and SwiftUI. From menu-bar helpers to full professional tools, distributed through the App Store or as signed, notarized installers.
02 · Android
Your users are not all on one platform — and neither are we. We bring the same care for detail to Android, so your app reaches everyone with one consistent experience and one shared idea behind it.
03 · Cloud
When spreadsheets and e-mail chains stop scaling, we build the platform that fits: member and course administration, bookings, portals and data services — shaped around how your organisation actually works, not the other way round.

Gas selection, fill planning & dive analysis.
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.
Dive logbook & analysis.
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.
Decompression planning.
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.
Prioritize CVE risks locally.
Security alerts are abundant, triage time is not. CVE Agent turns public CVE feeds — NVD, CISA KEV, FIRST EPSS, CVE List V5, CERT-Bund (BSI), ENISA EUVD, CERT.at, vendor CSAF advisories and Metasploit/Nuclei indicators — into a focused, local workspace for IT security professionals: spot risk, relate it to your own environment and prioritize the next action on visible evidence — no black box, and your working data never leaves your Mac. Version 1.16 brought the Liquid Glass interface for macOS 26/27, favorites with change alerts and a multi-select vendor filter with up to 16 vendors of your own. Version 1.17 adds a dynamic vendor watchlist that grows automatically from CISA KEV, CERT-Bund and EPSS signals and a self-healing hourly background check that also resumes right after your Mac wakes from sleep. Version 1.18 guarantees complete 6, 12, 24 and 72 hour ranges, adds a “Since last visit” view and a “Type of change” filter, and shows how current the report is. Version 1.19 adds early warning from ENISA EUVD, CERT.at, vendor advisories and Metasploit/Nuclei, the CISA SSVC rating in every row, and a Sources settings pane to switch each source on or off.
Bring your AirPods back to your Mac.
Your AirPods hop between devices. Homing brings them back to your Mac with one click in the menu bar or a global shortcut — no digging through the Bluetooth menu. Optionally switches audio output and microphone to the headset the moment it connects. Sandboxed, no network, no analytics. Free and open source (MIT).
One link at a time: LAN first, Wi-Fi as fallback.
Docked Macs often keep Wi-Fi and Ethernet up at the same time, and traffic takes whichever path it pleases. MultihomingGuard fixes that for managed fleets: a root daemon verifies the wired path — link, IPv4/IPv6 with gateway and a DNS answer over that very adapter — before it takes Wi-Fi out of the picture, puts wired before Wi-Fi in the service order and flushes the DNS cache on every switch. Switching Wi-Fi off means the Wi-Fi service loses its address, not the radio: unlocking with Apple Watch, AirDrop, Handoff and Sidecar keep working. Unplug the cable and Wi-Fi is back within a second. iPhone USB tethering counts as wired and is parked while a real LAN is up. 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 a resolver of its own — proven with a query over that very link before anything is changed. With nothing connected at all the menu reports offline instead of claiming Wi-Fi. Users never see a password prompt; a hidden admin mode pauses the guard with admin credentials or a one-time support code. The app updates itself from a signed manifest, one click, no password. Ships as a signed, notarized pkg you install yourself. Localized in English and German. No telemetry, nothing leaves the Mac.
Signed with Developer ID and notarized by Apple (malware-scanned by the Apple notary service, ticket stapled, Gatekeeper-verified). Build 2.0.4 (155) · 2026-10-02 · 1.2 MB · SHA-256 d6d9b8fdc067505c3e4325c836b4dd0f898103357e3b47c83d209ab1a1cda387. Installs a menu-bar app and a root LaunchDaemon; requires an administrator to install.
