About this app

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 — from simple greetings to complex, literary sentence structures.

🎯 WHO IS MORT404 FOR?
- Foreigners who want to actually speak Polish — not just pass tests
- People tired of traditional language apps
- Anyone who wants to hear and feel the language before analyzing it

🧠 HOW DOES LEARNING WORK?
Mort404 is based on the proven input + output method:
1. Listen – every phrase is spoken by a native speaker
2. Repeat – shadowing lets you practice pronunciation in a natural rhythm
3. Internalize – chunks stick through context, not memorization

Each lesson moves through several stages — from first contact with a phrase, through active practice, to using it freely.

📚 WHAT'S INSIDE THE APP?
- Over 4,700 phrases and sentences — from basic greetings to advanced, literary constructions
- Phonetic transcription for every phrase (can be toggled on/off)
- English translations
- A leveling system — content grows with you
- Card collection — gather mastered phrases and track your progress
- Configurable accent profile and speech speed

❤️ LIVES SYSTEM AND DAILY PRACTICE
Mort404 motivates regular practice with a 5-lives system. Make a mistake — lose a life. Lives regenerate over time, encouraging short daily sessions instead of rare marathons.

Track your learning streaks, completed lessons, and mastered phrases.

⚙️ SETTINGS TAILORED TO YOU
- Toggle phonetic transcription
- Toggle spelled-out notation

🔒 NO SIGN-UP, NO CLOUD
Open the app and start learning right away — no account, no email, no login. Your progress is saved locally on your device only. No external servers, no data sent over the network.

Mort404 is free. It's supported by ads — no hidden fees, no subscriptions.

📵 NO UNNECESSARY DISTRACTIONS
The app is designed to keep you focused on the language — a dark, minimalist interface removes everything that doesn't serve learning.
Learn Polish through listening, repeating, and real-life sentences.
