Duolingo has a fully hatched course in its incubator program , in which new languages are added to Duolingo.
The course in Hebrew is now in public beta.
Go on and give it a try!

I've tried the Hebrew version of Word Fireworks .
It costs $2 and available from the App Store, Google Play, and Amazon.
It's definitely a beginner app and probably best for picking up the writing system.
The app involves tracing Hebrew characters with your finger so you can communicate with aliens using pyrotechnics.
The app appears to be only available for languages that have writing systems very different from English (also Japanese, Chinese, and Korean).

To add to the other resources mentioned here, I know of a Beginner Hebrew app and the Hebrew Locker app , both for Android.
Both apps work primarily on the basic Hebrew vocabulary and help you learn the commonly used Hebrew words and phrases from scratch and at your own pace.

I just found Free WordPower that seems similar to Duolingo.
It has assessment built in.

For learning the alphabet, I have found the Android app "Write it!
Hebrew" by Jernung to be especially helpful.
It allows you to trace the letters and you can set up your own custom tests (or ask to be tested on the entire alphabet).
On the downside, it does not offer any assistance with Hebrew cursive, but learning the basic block forms is a huge step up in making it to cursive.
I have no affiliation with the app author.

The best free Hebrew site that I have found and like to use is Teach Me Hebrew .
In addition, Learn Hebrew Pod has many free lessons.

There's an app called HelloTalk that I highly recommend.
It works like a typical language exchange, so someone would work with you in Hebrew in exchange for you working with them in another language you know well.

I am looking for an app or website for learning basic/beginner Hebrew. Since it's a less common language, Duolingo and other common programs do not have a Hebrew version. I'm looking for a free program with built in review and assessment.  This isn't a Google question. I have done many searches and not found any high quality programs that meets these simple criteria.
Are there any free apps or web sites for learning Hebrew?

Free WordPower is similar to Duolinguo and Teach Me Hebrew is a free Hebrew learning site, or you can try the alphabet app Write It or the language app HelloTalk. WordPower and Teach Me Hebrew are free language sites for learning Hebrew. However, if you are looking for an app Write it and HelloTalk are both good options.
