LumenBirch Interactivean app label of AM Skufca d.o.o. · Ljubljana

Guides you can read in the field, with the signal off.

LumenBirch builds small Android apps with nothing behind them: no account, no connection, no adverts, nothing to buy. The current one is Zeliscar, a calm guide to herbs and the plants people have long grown, gathered and cooked with.

THE STUDIO

A plant guide is most useful exactly where the signal isn't

The places people actually look things up — a hedgerow, a hillside path, somebody's allotment, a kitchen with the phone on the windowsill — are not reliably connected. An app that fetches its pages on demand fails precisely when it is wanted, and an app that wants an account first fails a little earlier than that.

Zeliscar holds everything in the download: every plant page, both languages, the images, the search index and the glossary. It opens the same in a cellar as on wi-fi, and it asks for nothing on first launch except which language you would like to read in.

The entries gather traditional, cultural and culinary knowledge — what plants have been called, where they grow, how they have been used in cooking and custom. That is the whole remit, and the app is careful to stay inside it.

THE APP
ZELISCAR

A Little Garden of Herbs

CULINARY WILD FLOWERS

Every plant has a story, a scent and a place in the old traditions. Zeliscar is a calm, browsable guide that gathers what people have long known plants by and used them for: the names, where they grow, how they have been used in cooking and folk custom, their flavour and character, and the facts worth knowing — each on its own page.

It is built to explore and to keep. Browse by category, search for any plant, and bookmark favourites into a collection you can return to. Flip through them as cards, meet a plant of the day, and read a glossary that explains the terms. A gentle companion whether you cook with herbs, forage, or simply like the green world around you.

Zeliscar shares traditional, cultural and culinary information for interest only. It is not medical advice, it does not describe treatments, and nothing in it should be used to diagnose or treat anything. For health matters, ask a doctor or pharmacist.

The vocabulary a guide is written in

No plant is named here and no use is described — this bench is pure shape. Build a sprig from the three things a field guide asks about first, and watch the botanical terms for what you have made. These are the words the app's glossary explains.

ARRANGEMENT ON THE STEM
Ovate, entire, opposite

A drawn sprig, three words and nothing else — no plant, no habitat, no kitchen use, nothing to bookmark. Zeliscar is the guide those words are written in, in Slovenian and English, entirely on your handset.

An entry that reads oddly in Slovenian, a traditional use you know differently, or a question about privacy — the mail reaches the person who wrote the app. Pišete lahko tudi v slovenščini.
