Läxi

Läxi puts one word on your home screen each day.

That is the whole idea. The widget is not an add-on, it is the product. You see the word while you are doing something else, and over a few weeks that adds up.

BUILT TO BE QUIET

No streaks. No notifications asking you to come back. No counter that resets and makes three weeks of work feel wasted. If you skip a day, nothing is lost. Words you have started learning come back when they are due, and that is all.

SIX LANGUAGE PACKS

Swedish from English or German Spanish from English or German English from German German from English

Each pack covers A1 to C2 and is ordered by how often a word actually appears in real text, so the first words you meet are the ones you will meet again.

EVERYTHING STAYS ON YOUR PHONE

No account. No sign-up. No server. The app makes no network requests at all, which is why it works on a plane, in a tunnel, and abroad without a data plan. Your progress never leaves the device.

SPACED REPETITION

Läxi uses FSRS, an open scheduling algorithm, to decide when a word is due. Words you find easy come back rarely. Words you keep forgetting come back sooner.

OPEN DATA

The language packs are built from open dictionaries and corpora: Wiktionary, FreeDict, Tatoeba, the Swedish Kelly list, Folkets lexikon. Every source is named inside the app under Sources. Nothing was taken from a commercial dictionary.

WHAT IT DOES NOT DO YET

Swedish has fewer example sentences than the other languages, roughly two thirds of entries rather than nearly all. The open sentence collections simply contain less Swedish. We would rather say so than let you discover it.

Läxi is Swedish wordplay. Läxa means homework, lax means salmon. Hence the fish.
