A great tool

I’m learning BSL and this is a fantastic reference app and it’s really good to see different people signing.

However, I wish there was a ‘sign of the day’ feature. I would use it more as a vocab builder then.

Needs work

The app is good with videos for the words I’m searching for. However the ‘previously searched words’ are not mine, so each time I go on the app there’s loads of quick links to weird words. I want my previous ones to be displayed so I can refresh when needed. It’d be helpful to be able to save favourites as well and have categories to help me better search for appropriate words.

An excellent app!

What an amazing app! I’m not deaf, but love to use BSL as a teaching tool to help scaffold learning, making language more accessible to visual and kinaesthetic learners.

Sign BSL is not only easy to use, it’s comprehensive, dynamic, and the developers have worked hard on improvements, adding definitions to make signs more explicit. They’ve also added additional features eg zooming, to make for more accessible functionality.

Finally, the support team are great! They are open to suggestions and are 100% responsive.

Thank you for helping us to access the incredible language of BSL.
