Echo: Language Learning

Echo helps you learn a language with the sentences that matter to you. The phrases you actually use during your day, not someone else's word lists.

Echo is a tool, not a course. You create your own sentences in your language and your learning language, then practice them. There are no ready-made lessons or learning content. You bring the sentences and put in the effort, and that's exactly what makes them stick.

Two proven methods, one simple app:

• Shadowing: First, listen to your sentences with natural text-to-speech and repeat out loud to train pronunciation and rhythm.
• Active recall: Then see a sentence in your language, recall it yourself, and reveal the answer.

SMART SCHEDULING
Echo uses FSRS, a modern spaced-repetition algorithm, to show each sentence right before you forget it. Sentences you miss come back in minutes; mastered ones in days or weeks.

BUILT FOR FOCUS
• Add your own sentences in 12 learning languages
• On-device translation suggestions to help you add a sentence always check them, as they're a helper, not a guarantee
• Free practice mode that doesn't affect your schedule
• Progress overview with per-sentence status
• Daily reminder showing how many reviews are due
• Optional iCloud sync across your devices
• Export and import your data anytime

SIMPLE ON PURPOSE
Echo deliberately stays minimal so you can focus on your own sentences. No courses, no feeds, no distractions, just a calm space to practice what matters to you.

PRICE
Free to download and use for up to 20 sentences. A single one-time purchase unlocks unlimited sentences, no subscription, ever.

PRIVATE BY DESIGN
No account. No ads. No tracking. Your data stays on your device or in your own private iCloud. The developer never sees it. Translation and speech run entirely on-device.

Interface available in English, German and Spanish.
