What it does
JustSpeak is an AI-powered language learning app designed to help users improve their spoken English. It provides a personal AI tutor that engages users in conversational practice through various lessons and role-play scenarios. The app focuses heavily on providing real-time feedback on pronunciation, grammar, and vocabulary to build speaking confidence.
Where it shines
The app's strength lies in its interactive learning model. The onboarding process culminates in a mandatory AI chat at 01:25, giving users an immediate taste of the core experience. This is far more compelling than a simple feature list. Another highlight is the granular feedback system. At 02:06, the app provides a percentage score for pronunciation and a detailed explanation, which is a powerful tool for improvement. The tap-to-translate feature, seen at 03:06, removes friction by integrating a dictionary directly into the conversation, allowing for seamless learning.
UX highlights
- Deep Personalization: The onboarding quiz (00:14 - 01:17) goes beyond basics, asking about specific goals, interests, and even anxieties to tailor the learning plan.
- Interactive Data Visualization: When setting a daily goal (01:09), the app displays a dynamic graph projecting the user's future confidence, making the commitment feel tangible.
- Contextual Learning Tools: The ability to tap any word for an instant translation and definition within a conversation (03:06) is an excellent, low-friction feature.
- Immediate, Granular Feedback: After each spoken response, the user receives detailed grammar and pronunciation analysis, as seen in the lesson summary at 09:07.
- Gamified Progress: The app uses day streaks (09:31) and celebratory confetti animations (04:10) to motivate users and mark milestones.
- Structured Role-Plays: The main dashboard offers a wide variety of specific, real-world scenarios like 'Job Interview' or 'At a Coffee Shop' (11:35), providing goal-oriented practice.
Monetization & growth
The app uses a free trial model with a paywall that appears after the initial AI chat demonstration (04:34). It presents two subscription options, highlighting the monthly cost of the annual plan to make it seem more affordable. The paywall builds trust by including a visual trial timeline (04:48) and user testimonials (04:51). A toggle to receive a notification before the trial ends is a user-friendly touch that can reduce subscription anxiety.
Who it’s for
JustSpeak is aimed at intermediate English learners who want to improve their conversational fluency and confidence. Its focus on speaking practice and real-time feedback makes it ideal for users preparing for specific situations like job interviews, travel, or exams. The app also caters to those who feel anxious about speaking with real people, offering a non-judgmental AI partner for practice.
Notes & opportunities
While the personalization quiz is thorough, its length could be a point of friction for some users before they experience the app's value. The immediate, un-warmed-up system permission prompts for tracking (00:00) and notifications (01:17) feel abrupt and could be better framed with a pre-permission screen explaining the benefits. The main dashboard is well-organized, but a search function for lessons could improve discoverability as the content library grows.
