This definitely rings true. I was using it in the hopes it would help me provide some structure to teaching my kid portuguese (and it does to some extent), but by the time the app says a lesson is "complete", my kid is still a long ways away from having memorized it (and he's 5). I tend to complement it with a boogie board and repetition over the course of several days to really nail down new vocab.
I also wish it had some feature to introduce foreign concepts (e.g. gendered articles in portuguese). It's very awkward to try to explain the difference between `the`, english `a`, and portuguese `a` (and the remaining counterparts `o`, `um`, `uma`) for example, and the word matching exercises can get quite confusing.
You can't just keep taking new lessons. You have to do "strengthen skills" or go back to practice older lessons on a regular basis. In fact, the new scoring system they just released with levels (crowns) for each lesson is supposed to emphasize this; to really complete something, you have to go back and practice it many times.
When I do duolingo, I usually try to do about a two to one ratio of strengthening skills or going back to older lessons with taking new lessons.
