BG Trainer A0

BG Trainer is a focused grammar drill app for absolute beginners learning Bulgarian. Designed for Russian and Ukrainian speakers (East Slavic background) starting at A0 level.

WHAT YOU PRACTICE
• Verb "to be" (съм/си/е/сме/сте/са)
• Possession verbs имам / искам / мога
• Definite articles (-ът, -та, -то, -те)
• Grammatical gender — masculine, feminine, neuter
• Plural forms — regular and irregular
• Possessive pronouns
• Negation
• Question word order with particle "ли"
• Numerals, time, dates
• Present perfect tense
• Food, taste, restaurant vocabulary

HOW IT WORKS
• 8 progressive lessons (L1–L8)
• 240 drills and over 4000 questions across 12 formats — multiple choice, keyboard input, sentence building, particle insertion, matching pairs, paradigm tables, timed quizzes
• A round of three short games in a row
• Instant feedback after every answer with the correct form and a short rule
• Weak and long-unpracticed items come up first, and a mistake returns later in the same session
• Mastery tracking per item, session history and progress charts

BUILD THE SENTENCE YOURSELF
Every lesson carries a production drill: you read the translation and produce the Bulgarian sentence. The scaffolding fades as the course advances — labelled roles and a word bank at first, then bare blanks, then an empty line, and in the last lessons you type the whole sentence.

CLEAR THE FIRST TIME
• A worked example sits above every question, so the shape of the expected answer is never a guess
• The hint and the verb-form table open from the header and stay out of the play area
• Four text sizes, following the iOS system setting by default

INTERFACE
• Russian or Ukrainian UI (your choice)
• Three pace presets: quick (3 questions), standard (5), long (8)
• Light theme tuned for focused study
• Works offline — all content bundled, no account required

ALL INCLUDED
• All 8 lessons (L1–L8) included — one-time purchase
• No subscriptions, no ads, no tracking

PRIVACY
All learning progress is stored on your device. We do not collect, transmit, or sell any personal data.
