Grammobolica is your Language Gym — a daily training space for adults who studied a language before but still can't speak it. The goal: speak out loud every day. Real reps, not streaks. Pick a topic, do 3 sets of 10 sentence translations aloud, get checked by your native coach. Grammobolica trains you to actually USE grammar — not just read rules. Say full sentences aloud, get graded word by word, and build a vocabulary that comes straight out of your own mistakes. Learn English, Spanish, German, French, Portuguese, Polish, Indonesian, or Serbian. NEW IN 3.1.6 Refreshed Interface Cleaner screens and a new checkpoint after every set.

Translate from your language out loud, then reveal and check. Missed some? A short extra round replays exactly those. Voice Mode Speech recognition checks your spoken answer against the target sentence. A word only counts if it was hidden when you said it — reading it off the screen doesn't.
