Most English apps show you streaks and XP. That tells you how often you opened the app. It does not tell you whether you got better at speaking English. There's a difference.
Enverson AI tracks the metrics that actually represent speaking improvement: fluency rate, accuracy, pronunciation, vocabulary range, response latency — and charts them over weeks and months so you can prove progress to yourself, your boss, or your future self.
Auto-generated every Sunday: time practised, what improved, what regressed, suggested focus for next week.
Charts showing month-over-month change on every metric.
