SpeakApp Habit Loop and Lessons — 01 — Splash screen & daily habit dashboard

The Problem Space

Language apps live outside daily messaging flow: heavy lessons, paywalls and installs kill the habit before it forms — especially for beginners who need 3-minute sessions, not 30-minute marathons.

Core Challenge: Ship a complete learning loop inside Telegram's constraints as a solo designer-developer: structured curriculum, multiple practice modes, streaks and progress — zero install friction, fixed dark TMA viewport.

Solution & Architecture

Lightweight Mini App: 54-lesson curriculum chain with level gates, 6 practice modes (flashcards with second-chance round, choice, typing, listening with 500 audio files + TTS fallback, sentence building, auto-generated phrases), XP / streaks / achievements / dictionary — synced via Telegram CloudStorage + LocalStorage with a server snapshot.

SpeakApp Flashcard Practice — 02 — Flashcard practice & swipe gestures

Core Scenarios

The daily habit loop centers on a single home screen with instant level progress, XP counters, streak calendar, and topic catalogs. Lessons offer four focused practice modes — Cards, Choice, Writing, and Audio — supplemented by sentence construction and auto-generated phrases. Flashcards use tactile swipe mechanics with second rounds for missed words, while listening exercises autoplay with smooth TTS fallback.

03 — Audio listening mode & profile stats

Key Engineering & Design Trade-offs

CHOICE Telegram Mini App

Zero install inside a daily habit beats store discovery — especially for a solo launch with no marketing budget.

CHOICE Fixed dark + 480px frame

Telegram clients force light themeParams unpredictably; locking dark from the first frame kept contrast and flashcards readable.

CHOICE Curriculum chain + gates

Sequence (level + order + required words, deadlock-free) guides beginners; an open dump of 54 lessons would paralyze them.

Transformation

BEFORE

Heavy apps with long lessons and paywalls — learners drop off before a habit forms, and practice lives outside daily chats.

AFTER

Zero-install TMA entry, topic catalog with level gates, one-tap lesson start and a 3-minute loop: card → guess → confirm — sessions fit into chat breaks.

Outcome & Measured Impact

Just launched in open beta — all lessons free while collecting feedback. No retention metrics yet by design; the shipped scope (design to code by one person) is the result. Next: feedback loop via channel, then Stars paywall and spaced repetition.
