Strengthen Button on Android

What is the functionality of the strengthen button on the Android app? It seems to be presenting the same material, not material throughout the tree. I would think that I would be stronger in the material just presented, so it would present other material in the tree. (If it matters, I'm on the crown system.)

If you go to , you can see what the strength is for each of your skills. If you sort that table by date (completed), you can see which the first skill is that is below 100% strength. The Practice button will target this “earliest” skill not at full strength for a practice session. If you don’t use the button regularly, it will seem like the practice button is only targeting these early skills in the course.

If you want to bypass the button, you can launch a practice session directly from the duome page using the little barbell link next to each skill. But this will only work for the website version. :-(

Unrelated question. If I go to, I noticed that some of the leaves don't have a Tips & Notes icon. I'm assuming that those leaves don't have a Tips & Notes page. Is that correct?

Also, is this the only way to get to the Test Out button for each leaf? I don't remember one on the Duolingo site for individual lessons. (Or am I just not paying attention?)

You are correct, there are no tips and notes for several of the skill leaves on your French course.

I don’t have the android app so I don’t know all of it’s functionalities. I would assume that the test-out function (little key thingy) is available on the app when you select a skill. It is definitly available on the website version.

When you select test-out for a skill (which I don’t really use) it allows you to test out of an entire crown level, which may be anywhere from 2 to 10 lessons.

Hope that helped. Part of the confusion is that we all have different versions of Duolingo, there are even different versions of the Android app and different versions of the French course. Which is just annoying. But Im relatively sure what Ive said applies to everyone.

Do a skill order by "original (tree) order" and you can guess your next skill < 100% strength from top to down.

The global blue strengthen button may jump over the first few skills.

At least this is how the PRACTICE button works on the web portal.

The Strengthen skills lessons choose words from throughout the course that Duolingo thinks you need to revise. The first few times you use it, those words will be from skills towards the start of the course.

It's only worth using once all of the skills have been brought back to gold. You can see which of your skills have decayed, using

The more you use the Strengthen lessons, the better it gets to know you. It's frustrating to start with, but after a few days it'll start to do a better job of giving you things you tend to get wrong, rather than just the easy stuff from earlier in the tree.

Thanks for the responses. I think the gist of your comments is that I need to be a bit more patient. (I'm starting each day with the Strengthen button, then following up with new material.)

I'm primarily using the Android app, since it's far more comfortable on my couch than sitting at my computer. If I don't get new material by the end of the year, I'll switch over to using my computer. Maybe I could buy a more comfortable chair?

As for a gold tree? That's probably a long way in the future. Right now I'm aiming for a blue tree before my tree is switched out for the V4 tree (theoretically sometime early next year).

If you haven’t been here for very long, what you may not know is that up until abt 6 month ago, there was no such thing as crown levels. It was just one level for each skill, but you had to try to keep your skills strong/gold through “practice”.

Then they intro’d crowns and sort of demoted the whole concept of practice/skill strength. The duome page is sort of a work around (not produced by DL itself) that allows those of us who want to keep montioring skill strength.

The strength algorithm does help you review by favoring 1. Older material 2. Harder material 3. Material you haven’t touched in awhile. That’s why I use it. But its not perfect and I think you can use it too much and feel like you’re on a hampster wheel. Once/twice a day is good.

I pre-date the crown system, so I know the old system. But thanks for reminding me.

I only do one strengthen lesson a day before looking at new material. Part of the rationale is the race between me and the system. I want to at least get a blue tree before they replace/upgrade the tree. (Not that I won't be happy working on the new tree, just that I'd like to have something to brag about, albeit small.)

I hear that. Priorities.
