Your data goes absolutely nowhere.
Four programs for people doing precise work: invoicing, loading a truck, covering a room, hanging a lighting plan. No account. No subscription. No server listening in.
OhmniaThe spreadsheet that eventually betrays you.
A formula deleted by mistake, a total that no longer adds up, and nobody to spot it before the audit.
Ohmnia handles invoicing, quotes, time tracking, inventory and simplified bookkeeping for a sole trader. Every division is guarded, every calculation lives in one place, and the numbering never skips.
ScenikaThe truck is loaded. One stand is missing.
The audio and lighting inventory of a rental company or a technician: what you own, what is out, what never came back.
With power calculation per circuit and DMX addressing tied to the real inventory. Stock does not move when equipment leaves: what is out is calculated, otherwise one forgotten rental leaves a figure nothing ever puts right.
AdressoThe patch is right on paper. It is not right at the end of the cable.
Scenika's DMX calculator, free and with no account: addresses, universes, overlaps. Nothing is stored, everything is worked out in your browser.
A map of all 512 channels shows the occupied blocks, the gaps, and above all the overlaps, at a glance. The addressing step is shown just as you type it into a console — and when it is not constant, the page says so instead of inventing an average you would copy out.
AcustikaA colour map is very convincing. Even when it is wrong.
Acustika computes the coverage of a room — and says where to put the boxes, not just a map you have to know how to read.
Freely drawn zones, raked seating, directivity per band, section view, alignment delays. And the room itself: absorption, reverberation, critical distance. The advice stays a proposal — the real room never matches the model, and the application says so instead of keeping quiet.
LumikaThe dimmer rack eats twenty-four channels. Everyone forgets.
The lighting plan of a theatre: the bars, the inventory, the hung fixtures, and the patch.
A conventional fixture wants a channel; a LED wants an address. A bar placed inside a rack's range works perfectly on paper and lights random circuits on stage — Lumika compares the two in the same space, and says so before the rig.
Nothing leaves your computer.
No account to create, no subscription to expire, no usage tracking. The only possible network access is the update check, and it is off by default.
One exception, and you are the one who chooses it: multi-workstation mode, which makes your machines talk to a server you install yourself, on your network. Without it everything works offline — that is the default, not a lesser version.
Readable formats, simple code, MIT licence. In ten years your files will still open.
That is it. That is the whole idea.
The rest — what each program does exactly, what it does not do, and how to download it — is on the site.
