The app is a warm-up, not the workout. What broke the plateau for me was a cheap weekly conversation hour with a tutor online — 60 minutes of being politely forced to speak beats 90 days of tapping.
Three months in and my streak on the usual app is 90 days but my actual speaking is… not 90 days good. What actually moved the needle for you? Looking for things that survive a busy work week, not another subscription I'll abandon.
