## What is 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.

## Version history (last 2 releases)

### 1.1 — 2026-08-09

A big update: a new drill, a worked example on every question, and text size settings.

Build the sentence yourself. Every lesson now 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, and in the last lessons you type the whole sentence.

Clear the first time. A worked example now sits above every question, so the shape of the expected answer is never a guess. The hint and the verb-form table moved into the header and no longer take up room in the task itself.

Bigger and easier to read. Four text sizes were added, and by default the app follows the iOS system setting. Type is larger, greys are higher-contrast, and long answer options wrap instead of being clipped.

Nothing scrolls out of reach. The question and the slots you fill stay pinned at the top, and in the paradigm drill the pool of forms is pinned at the bottom. The verdict is shown in the centre of the visible area.

Progress counts honestly. Accuracy after a session is the share of questions answered right on the first attempt, and paradigms now count every form separately.

### 1.0 — 2026-07-10
