About Mort404
Mort404 is a Polish language learning app that works differently from all the others.
Instead of teaching grammar through rules and tables, you dive straight into the language. You learn through chunks (ready-made phrases and sentences), shadowing (mimicking a native speaker's pronunciation), and progressive repetition β from simple greetings to complex, literary sentence structures.
π― WHO IS MORT404 FOR?
- Foreigners who want to actually speak Polish β not just pass tests
- People tired of traditional language apps
- Anyone who wants to hear and feel the language before analyzing it
π§ HOW DOES LEARNING WORK?
Mort404 is based on the proven input + output method:
1. Listen β every phrase is spoken by a native speaker
2. Repeat β shadowing lets you practice pronunciation in a natural rhythm
3. Internalize β chunks stick through context, not memorization
Each lesson moves through several stages β from first contact with a phrase, through active practice, to using it freely.
π WHAT'S INSIDE THE APP?
- Over 4,700 phrases and sentences β from basic greetings to advanced, literary constructions
- Phonetic transcription for every phrase (can be toggled on/off)
- English translations
- A leveling system β content grows with you
- Card collection β gather mastered phrases and track your progress
- Configurable accent profile and speech speed
β€οΈ LIVES SYSTEM AND DAILY PRACTICE
Mort404 motivates regular practice with a 5-lives system. Make a mistake β lose a life. Lives regenerate over time, encouraging short daily sessions instead of rare marathons.
Track your learning streaks, completed lessons, and mastered phrases.
βοΈ SETTINGS TAILORED TO YOU
- Toggle phonetic transcription
- Toggle spelled-out notation

π NO SIGN-UP, NO CLOUD

π΅ NO UNNECESSARY DISTRACTIONS
The app is designed to keep you focused on the language β a dark, minimalist interface removes everything that doesn't serve learning.
