What it does
ISSEN is a language learning app that uses an AI voice tutor to help users practice and improve their speaking skills. It moves beyond simple flashcards by focusing on active conversation. Users can engage in structured lessons, real-world scenarios, or open-ended chats with an AI that provides real-time transcription and interactive learning tools.
Where it shines
ISSEN's strength lies in its conversational interface. The app's ability to let you tap a word mid-sentence for a definition (01:46) is a standout feature, seamlessly blending learning with practice. Another highlight is the flexibility within a lesson. At 02:32, the user effortlessly pivots the entire conversation to a new grammar topic, demonstrating a responsive and adaptable learning environment. Finally, the ability to choose a tutor with a specific regional accent during onboarding (01:01) provides a level of authentic, real-world preparation that many apps lack.
UX highlights
- In-Call Vocabulary Saving: Tapping any word in the live transcript instantly provides a translation and a 'Save' button. This makes vocabulary building frictionless and contextual.
- Multi-Modal Practice Hub: The main screen (04:31) isn't a static dashboard but an action-oriented menu offering various practice modes like Grammar lessons, Scenarios, and 'Repeat after me' drills.
- Granular Session Controls: During a call, users have access to playback speed controls (01:41), rewind/forward buttons, and a menu to change topics, giving them command over the learning pace.
- Tutor Personas: The app presents AI tutors with names, ages, and home cities. This simple detail creates a surprisingly strong sense of connection and personalization.
- Integrated Flashcards: Words saved during conversations are automatically turned into flashcards (06:42), closing the loop between active practice and passive review.
- Detailed Statistics: The app provides a clear breakdown of study time, sessions, and saved words, along with a competitive leaderboard to motivate users (03:43).
Monetization & growth
The video does not show a paywall or any explicit monetization strategy. The user appears to be on a trial, as indicated by the '9 trial minutes left' text in the account menu (09:35). The app includes a 'How did you hear about us?' survey (00:52) in its onboarding, signaling a focus on understanding its acquisition channels for growth.
Who it’s for
This app is clearly for intermediate language learners who understand the basics but need to build confidence and fluency in speaking. It's ideal for those preparing for travel to a specific region, thanks to the regional accent feature. The user who wants to move beyond rote memorization and engage in active, responsive conversation would find ISSEN particularly valuable.
Notes & opportunities
The app experience is polished, but there are small points of friction. The system permission prompts for notifications (00:49) and the microphone (01:11) appear without a custom warm-up screen, which could be jarring for some users. Adding a brief explanation of why these permissions are needed would improve the experience. Additionally, while the app tracks a daily streak (06:24), integrating this more prominently on the main dashboard could provide a stronger daily motivation hook.
