Mahtavampi! This is really great for all us people not "on" 24/7 ;)

How will the app pick the lessons to keep? Will it keep track of the times exercises are done and sync back with Duolingo when being online again? (How about the streaks?)

well, I tested this out and it was pretty nice to be able to study while at school/work and no where near internet. Unfortunately, for me there was only about a half an hour of lessons. It would be nice if this app would store about 6 hours of lessons for each of like 3 languages, that way we have something to choose from. Maybe they could let us choose the data we want and how much of it before we log off that way it knows what to download when there is internet access. Maybe they can set up a set of settings for this feature, that we can set on our home computer or tablet, to govern/control our preferences. I'm not sure about anybody else, but I am willing to use my extra storage space on my tablet - just to be able to study for 6 hours at work/vacation/out in the boonies where no internet exists -- Please, make it possible?? Thank You :)

+1 Vote for a real offline mode, where you can select
- 2-3 skills
- 5-10 lessons per skill

Too bad that very often only one skill is unlocked on the home screen, as 10 lessons in one skill could not be taken in offline mode on my side; it stopped at 5 finished lessons.

Does offline mode work if you have finished the skill tree ?

EDIT: It seems if you finished skill tree the offline mode doesn't work because only new lessons are available in it.

EDIT2: It appears that if you have 1 lesson left in a unit and you finish that lesson in offline mode next skill will not be available. I'm not sure about this since I only gave duolingo 5 minutes to update, and I had 5 more lessons available in another skill.

I believe it will because once you go online, it should sync your progress data. Best way to find out is to test it in offline mode for a day or two. Seeing that I'm more of a n00b to this site and likely don't have near the streak most of you do, I'll test & post back.

I am using BlueStacks app player (Android emulator).

However for my Portuguese course only one lesson is downloaded offline / can be started. The next locked lesson can NOT be unlocked once you finish that one lesson before.

So the next lesson is already shown in offline mode, but I can not do multiple lessons as expected (30-60 minutes of lessons material for one skill or maybe even 2 skills).

I have now managed to execute (3-)5 lessons in a skill.
For the 2nd (parallel) unlocked skill I was even able to do new 2 lessons.

You have no real control over, how many lessons can be taken in total in offline mode. It was not always 5, but e.g 2-3 also.
And sometimes a new lesson (e.g 1-2/3 finished) could not be taken anymore as the message was "you have to connect to the internet".

I NEVER could take all 10 lessons in one skill! And I tried multiple times in the past weeks!

BTW: There is no real "airplane mode" in Bluestacks - at least I can not find it. But the home screen (practice button) is already aware of it's current "offline" mode.


The bad thing is that the Android app V3.39.2 after doing ~7-8 offline lessons in two skills just crashed. Each time I restart now the app, there is only the white screen in online mode and the app terminates. Tried it multiple times on Bluestacks and it does not recover anymore with WLAN/online mode.
It recovered once before when this happend before - dunno why.
Even APK re-install does not help, so probably the app data got corrupted...

Started a new thread:
(Reported) Bug: Android app V3.39.2+V3.40.4 does not start, terminated, data corrupted, 9 offline lessons done: https://www.duolingo.com/comment/20610216

The scenario is even worse:
The app even terminates on BlueStacks also when only 2+1 / 2+2 offline lessons have been finished (after the restart)! And app did not terminate itself before when finishing the 3rd/4th lesson!!!

The difference to the 9 offline lessons before is, that the app (later versions) at least starts and the tree with skills is quickly shown for ~1-3 seconds, before the app terminates again. So this is the difference.

I also tried the two newest app versions from February.

What is also quite funny: 1) "cp -R -f /data/data/com.duolingo /sdcard/DuoLingo_Backup/ did not fully backup on adb shell (there were warnings before)! Replacing the backuped package in /data/data/ makes no difference, my older lessons are not there anymore for a new online sync (e.g with one of the latest app versions).

2) Adb Backup / restore did NOT successfully backup my offline lessons. Nor are the lessons restored successfully. There must be hidden folders or files, which can not easily be copied / backuped.

@Android developer team:
Before doing this fancy Clubs, Bots and other stuff: Could you please help that the core offline functionality is at least working or can be debugged / traced? Or is this only a (my) problem on Bluestacks?

Please help!
Please also give in-depth tips how to handle backup and restore of offline lessons (app data).
It would help very much to be able to read a good manual or data / file handling (storage, reading) , tree-sync on startup specification! :-)

Thanks.

Link von "Der Deutschkurs für Arabischsprachige zeigt Erfolge" https://www.duolingo.com/comment/21576986 und Richtigstellung der "Offline-Mode" Beschreibung von https://wb-web.de/material/lehren-lernen/lernen-mit-duolingo.html in Deutsch:

Ich habe einen Kommentar auf wb-web.de zum dort falsch beschriebenen "Offline-Mode" angelegt.
.

Zitat: "DuoLingo ist offline verfügbar, d.h. nach dem Herunterladen steht es auch ohne Internetverbindung zur Verfügung."

Diese Aussage ist leider falsch.

DuoLingo unterstützt - im Gegensatz bsw. zum auswählbaren Memrise Handy App Offline Cache Mode (kompletter Kurs) mit der kostenpflichten Memrise Pro Mitgliedschaft - leider keinen echten Offline Mode.
Weder werden alle Skills und Lessons heruntergeladen, noch können alte Skills in diesem eingeschränkten Mode ohne eine Internet-Verbindung (WLAN, 3G) gestärkt werden.

Es werden lediglich 5 Lessons für 1-2 Skills angeboten, wenn man Glück hat.
Oft funktioniert noch nicht einmal das.
10 Lessons sind meinen bisherigen Tests nach auf Bluestacks (Android Emulator) nicht offline möglich. Man wird erneut aufgefordert, eine Internet Verbindung herzustellen. Diese Meldung hatte ich bsw. auch öfters bei neuen Skills auf dem Laptop bekommen und ich konnte nicht die Lesson 1-5 starten, die vorher freigeschalten (unlocked) wurden.
Auch hatte es mehrmals nichts gebracht, zuvor mit Internetverbindung in diesen Skill zu wechseln, den man später (z.B im Park auf einer Bank) offline durchführen wird. Mehr als 2 Skills konnten im Baum auch nicht für eine neue Lesson ausgewählt werden.

Die DuoLingo App mit ihrem "limitierten (cached) Offline Mode" ist meiner Meinung nach jedoch noch etwas verbuggt und hat starke Syncronisierungsprobleme.
So kann es bsw. vorkommen, dass 5 abgeschlossene (Offline) Lessons plötzlich nicht mehr mit dem DuoLingo Server syncronisiert werden können, sich die App regelmäßig beendet und nicht mehr starten will.

Meinen Tests nach auf BlueStacks mit der Android DuoLingo App (mehrere Versionen!) trifft dies sowohl bei 2-5 Lessons bei einem Skill, als auch einem Lesson-Mix für 2 Skills auf (z.B 2+1, 2+2, 5+4, 5+2...) auf.

Inwieweit dies auf einem Android Handy im Airplane Mode (kein Bluetooth, WLAN, 3G) besser läuft, muß ich derzeit bezweifeln, so wie sich die Android App bei mir verhält und scheinbar programmiert ist.
Ein IOS Handy habe ich nicht, um diesen ca. 30-60 Minuten "Offline-Cache-Mode" für 1-2 Skills auszutesten.

Ich mußte mehrmals ALLE abgeschlossenen Lessons wiederholen, zuletzt neu im Web, da nicht erfolgreich.
.
.
Fazit:
Bis die DuoLingo Entwickler ein "echten (wählbaren) Offline Modus" einführen oder den gemeldeten Bug (Bug Report) beheben bzw. dazu überhaupt ein Feedback geben (fehlt leider bis dato), ist es ratsam eine Handy App nahezu ausschließlich im Online Modus - mit Internet - zu verwenden.

How do you download a lesson for offline use, and how long does it take? When using the app on my android phone in the New York subways, where there often is no reception, the app tends to hang when I hit Submit, and then when I get to places with some reception, it works fast.

https://www.duolingo.com/Pixelstuff

Hi, you probably figured it out by now. On the iphone you have to go to airplane mode so duo really knows that offline mode is needed. Then you see all lessons greyed out but the last new ones are possible to use. You cannot choose which lessons to download and you cannot use practise mode. It only takes a few seconds to refresh. My local subways are just the same: up and down and confusing for an online owl ^^

How many lessons will be downloaded and how many can be started/finished offline?
If course specific, how many for DE-EN/EN-DE and EN-PT/PT-EN/PT-DE?

In offline mode (Bluestacks app player on PC) only ONE unlocked lesson can be taken without an internet connection.
I only see two lessons available in the skill, one (2nd) is locked. Once completed the next lesson is unlocked and could be started.
But when i click for the 2nd lesson on the start button it says: "Please go online to sync this lesson".
What also works is that the Android app shows a 3rd (locked) lesson as soon as the 1st lesson is completed.
It was not there before, as long as the 1st lesson was not completed and the 2nd lesson was still locked.

Hi Pentaan,

Quote: Since the introduction of "Duolingo Plus" you cannot download it for free anymore

Are you sure?

Maybe I could re-test with KOPlayer Android emulator software and one of the two recent DuoLingo Android apps, to re-test the crown L0 to L1 "10 lesson cache mode for 1-2 skills"?

It probably makes sense that somebody also re-tests the lesson cache mode for crown levels L2 to L3 (I have not a single L3 skill after the simple conversion in my EN-PT tree).

Personally I would have expected it to be working; why shouldn't it?

At least it was with an older app version partly with Bluestacks V3 for 1-3 quick lessons (without "DuoLingo Plus") as Luis had promised BEFORE crown level update.
However, I had not yet any chance to do a FULL / detail stability (app crash) test for 10 lessons across 2 skills....

I am curious:
What app (plattform) and versions have you tested the free lesson cache mode with?

Maybe staff had no time to re-test it with the latest crown level "overlay" update on the app?....everything could be ;)

Let me know what and how you are working on the test...

Viele Grüße in die NL

I did not test it myself, but I have seen too many complaints about:

  • cannot download in Android (non-Plus users)
  • results of lessons in cache don't synchronize with Duolingo's servers
    (Plus and non-Plus users)
  • lost my streak but I am sure that I have done my daily lessons
  • etc., etc.

I think, it would be even better that users of the App don't allow Duolingo to access their device's storage.
Reason:
In my test account for the Android App I have seldom issues in synchronizing.
On my Android phone (V 7.1.1) the Duolingo App does not have permission to use Storage and Contacts.
(Better safe than sorry)
