Fastlingo is built for calm, consistent progress. Instead of random phrases or grammar dumps, you learn through 10,000 carefully-graded sentences—each with a clear, concise grammar note. Every step adds just a bit more, so you keep moving without burnout, from A1 beginner to B2. Why Fastlingo works Continuous progression: Sentences are ordered so each one builds on the last—no jumps, no gaps. Micro-learning design: Small chunks of information that never overwhelm. Grammar that clicks: One focused explanation per sentence to make patterns stick. Largest organized set: 10k sentences curated for smooth, predictable growth. Four languages: German, Spanish, French, and English. How you’ll learn Start with very simple sentences. Read the brief grammar tip attached to each. Advance as you feel ready—each new sentence adds one manageable idea. Reach B2 with confidence built step by step. Perfect for self-learners who want structure without stress. • Learn Naturally: Build your speaking skills with real-life sentences. • Practical Grammar: Understand grammar in context, not as abstract theory. • Step-by-Step: Find your own pace and learn in a relaxed way. • Boost Retention: Key grammar concepts and vocabulary are repeated to ensure you retain them. • Modern method: Use the practice mode to make your learning more efficient. • Pronunciation: Record your own voice and compare it to the recording of the teacher or the text-to-speech voice. Also use voice recognition to test and improve your pronunciation. Terms of use (EULA) https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is ads: Friday15 at none against Fastlingo's shown. Fastlingo's advantage is update cadence (every 4 weeks vs every 3 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
