Read full descriptionHide full description
Real conversation practice in 8 languages with an AI partner that runs entirely on your iPhone. Talk as much as you want — no minute caps, no accounts, no data leaving your device. Your first conversation is free. 8 LANGUAGES Spanish (Spain, Mexico, Latin America) · French · Italian · Portuguese (Brazil, Portugal) · German · Swedish · English (United States, United Kingdom) · Japanese More languages coming soon. TALK AS MUCH AS YOU WANT No minute caps. No daily limits. No credits to run out. The AI lives on your phone, so there’s nothing to ration — practice for five minutes or an hour, as often as you like. FULLY ON-DEVICE. FULLY PRIVATE. Most language apps send your voice to a server. Digamo doesn’t — it can’t. Everything runs on your iPhone. Your voice never leaves your device, your conversations are never transmitted, and nothing is used to train anyone’s AI. We built it that way on purpose. No account. No email address. No tracking. No analytics. Just the app. HOW IT WORKS Tap the microphone. Your AI language partner speaks. You respond. That’s it. Digamo simulates real conversation — the kind you’d have with a native speaker — without needing another person on the other end of the line. When you don’t understand something, tap the flag to switch to your native language and ask. Get your answer, then switch back. Just like working with a real language partner. Long-press any word or phrase to translate it or hear it again. Digamo knows your level and adapts as you improve. BUILT FOR REAL PRACTICE No gamification. No streaks. No cartoon characters. No creepy AI avatars. No structured lessons — every session is real conversation, not a drill. Native language support — grammar explanations and translations in your own language. Adapts to your level from A1 beginner to C2 advanced. Personalize with topics you care about: travel, food, culture, business, and more. Grammar focus: target the specific patterns you want to improve. Everyday situations: practice at the doctor, ordering food, job interviews, and more. Playback speed control — slow down for comprehension, speed up as you improve. WORKS OFFLINE Once the language model is downloaded, Digamo works anywhere — on a plane, in the mountains, without Wi-Fi. The AI runs on your device, not in a data center. ONE PRICE. ALL FEATURES. Your first conversation (12 turns) is free. After that, Digamo’s language practice features require an auto-renewable subscription: Monthly: $3.99 per month Annual: $39.99 per year — best value No limits. No dark patterns. Every language and every feature is included in both plans. Family Sharing supported. Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current period. You can manage or cancel anytime from your App Store account settings. No one ever became fluent in a language by using an app. Digamo is one tool in your language learning journey — the best way to get real speaking practice, anytime, anywhere, without needing another person available. REQUIRES iPhone 15 Pro or later, or an iPad with M1 or later. Digamo runs a complete AI model on your device — that needs 8 GB of memory, so earlier iPhones and iPads aren’t supported. · iOS 26 / iPadOS 26 or later · 16+ TERMS OF USE https://digamo.ai/terms/ PRIVACY POLICY https://digamo.ai/privacy/
