Lots of words signs covered by play icon.

This app has a lot of words to look up which is very helpful. I only gave it four stars because the “play, skip ahead and back” icons are right where the signs occur which make it hard to see the signs.

One of the best free video dictionaries

I really appreciate that this app allows you to see multiple sources and signers for the same word. This not only assures that you are finding the right sign conceptually, but also gives you a taste of different versions and signing styles you might see.

This is my go-to app for a quick sign check!

My only complaint is that sometimes the result most directly related to your search does not end up first on the page. Additionally, occasionally the far less common definition of a word will be listed first.

Helpful but unreliable

I like the idea, and I appreciate that it’s free, but it’s riddled with incorrect signs, which is very unhelpful when you are starting to learn. (It can be much harder to unlearn incorrect information than to learn new correct information).

In particular I think that one of the sources they draw from called “SmartSign Dictionary” gives consistently incorrect signs (and not just a little off, but completely and weirdly wrong). If they could fix this, and make sure they only drew from reliable sources then it would be a great app.
