Hey! I'm launching LUMO a German vocabulary app on Product Hunt tomorrow (Aug 19).
A bit of background: I built this solo, from the content pipeline to the app itself. Every word is organized by CEFR level (A1 to C1), with spaced repetition, real example sentences, and a dedicated tool for finally mastering der/die/das.
LUMO helps you learn German vocabulary the structured way — from beginner (A1) to advanced (C1). Instead of random word lists, everything is organized by CEFR level, five words per module. Spaced repetition flashcards, real example sentences, and a dedicated Der/Die/Das studio help it actually stick. Built solo — nearly 1,900 words reviewed so far, more added weekly.
