Welcome to Sparkling — the new way to learn vocabulary. Sparkling is a modern language-learning app that helps you build real, lasting skills in German, English, Spanish, French, Swedish, and more. From A1 to C2, you get intelligent flashcards, varied exercises, and a repetition plan that adapts to what you actually struggle with—not what you already know. Adaptive learning that respects your memory Sparkling uses a multidimensional spaced-repetition system (SRS) that tracks separate strengths for vocabulary, spelling, and grammar. Cards return at the right moment so you train efficiently, tuned for language learning with richer context, morphology, and smarter scheduling. Add words in seconds—typing, camera, or share Type a word in your native or target language and Sparkling can pull translations, grammar details, and example sentences automatically. Use the built-in scanner for photos, screenshots, or printed lists (including a dedicated vocabulary-list mode). You can also share an image straight into Sparkling so words are recognized and ready to add with a tap. Quick Training, Text of the Day, and Lessons Start Quick Training with one tap to practice what’s due right now. Read the Text of the Day at your level—tap any word to add it or analyze the sentence grammatically. Explore ready-made lessons or build your own, with AI assistance or fully manual control. Training you can shape In the Training tab you choose folders, word types, exercise mix, and focus areas—then start a session that matches your goals. Add your own free-text instructions when you want the AI to steer practice (for example tense focus, a level, or a topic). Exercise types include flashcards (including reverse mode), gap-fill, sentence ordering, matching, and translation-style drills—plus reading with authentic texts where available. Smart cards, folders, and imports Organize everything in folders, share sets with others, and learn with friends when you want accountability. Import common flashcard packages (for example .apkg) from your profile and keep studying your existing decks inside Sparkling. Progress, feedback, and motivation Track streaks, detailed statistics, and evaluations so you can see momentum—not guesswork. Optional haptic feedback celebrates small wins during study. For learners of all ages Whether you’re in school, at university, learning for work or travel, or brushing up for a certificate exam, Sparkling is built for short, regular sessions that fit real life.
Klar Speak

Most language apps have you tapping multiple-choice answers. Klar has you talking. Klar is a voice-first language tutor. You practice out loud in a real spoken conversation with an AI tutor that explains a word, gives examples, asks you to use it in your own sentence, and listens to your reply — all by voice. It's the closest thing to a patient one-on-one teacher in your pocket. LEARN BY SPEAKING, FROM DAY ONE Speaking is the hardest skill to build and the one most apps avoid. Klar is built around it. Start a session and you're talking within seconds. BUILD YOUR OWN WORD LIST You add the words you actually want to learn. Klar cleans them up automatically — translating, fixing the article and spelling, checking the meaning — so every entry is correct. The tutor then teaches those exact words and tracks each one from New to Learning to Learned. MEETS YOU AT YOUR LEVEL Set your level on the CEFR scale (A1–C2) and the tutor calibrates how fast and how richly it speaks. Beginners get slower, simpler language with an English hint when stuck; advanced learners get more demanding material. Change it any time, even mid-session. FOUR LANGUAGES, EACH ITS OWN Learn German, Spanish, French, or Dutch — each with its own native-sounding voice and its own separate word list, so nothing mixes together. MADE FOR REAL LIFE - Hands-free mode for practicing while walking or commuting - Adjustable tutor speed (Neutral, Slow, Very slow) - A curated Word of the Day pitched to your level - Light and dark themes - Your settings follow you across every device you sign in on PRIVATE BY DESIGN No ads. No data selling. No advertising trackers — so iOS never even shows you a tracking prompt. You can delete your account and all your data any time, right from the app. HONEST ABOUT AI The tutor is powered by AI and can occasionally be wrong — and Klar tells you so openly, right on the practice screen. PRICING Everyone gets 10 free practice minutes every 30 days. Klar Pro is $11.99/month for 200 minutes of tutor practice. Subscribers who want more can add a 100-minute top-up for $4.99.
