Get a day-by-day weekly schedule tailored to your level, goals, and available time. Based on research-backed activity ratios used by successful polyglots.
Fluency Streak logs your actual study time across all these activities — with streaks, stats, and shareable progress cards.
Download Free on iOSYour plan is based on activity ratios recommended by polyglots and language researchers. The optimal mix changes with your level:
The most common mistake language learners make is doing only one thing — just Duolingo, just flashcards, just watching TV. Research on interleaved practice shows that mixing different types of activities in a single study session improves retention by 20-40% compared to blocked practice.
That Reddit user tracking 14 different activity types across 300 hours? They reached near-native reading comprehension. Not because they found the "perfect" method, but because they varied their practice and tracked all of it.
About 80% of your time should be spent on input — reading and listening to comprehensible content at or slightly above your level. The remaining 20% goes to output — speaking and writing practice. This ratio, backed by Stephen Krashen's Input Hypothesis and validated by modern polyglots like Steve Kaufmann, is baked into every plan we generate.
A 30-minute daily habit outperforms a 4-hour weekend cram session. Your brain consolidates language overnight, so daily exposure — even brief — keeps neural pathways active. That's why we spread your hours across multiple days rather than concentrating them.
The hardest part isn't finding the right method. It's showing up every day. That's exactly what Fluency Streak is built for.
