Having trouble recalling a Braille contraction or the use of a specific symbol? This is the App for you! This App contains access to a database of over 1,000 Braille symbols, contractions, and commonly misconstrued symbols. This App allows for the lookup of contracted (also known as Grade 2) Braille signs using the Unified English Braille (UEB) code. The UEB code was established as a new standard by the International Council on English Braille. This Braille code has been adopted by Australia, Canada, New Zealand, Nigeria, South Africa, the United Kingdom, and the United States. You can also lookup Grade 2 Braille symbols using the older English Braille American Edition, as established by the Braille Authority of North America (BANA). Some basic Computer Braille Symbols and Nemeth Code notations are also available via the lookup feature.

You can search either by the dots you see on the page or by the English abbreviation or punctuation you seek. For example you can type into the "Dots Seen" field dots 1 2 3 and this will tell you that it is the letter "L" or the word "like" depending on context of its use. Conversely you could type in the word "like" into the English phrase field and it would tell you the Dots needed, which in this case is Dots 1 2 3. This App is intended to be used as a reference tool only; it does not function as a translation tool.

There is an index of all Braille contractions that can be browsed at a glance. You can view either Braille codes mentioned above or both at the same time. Also, while running lookups you can view both Braille code results for comparison purposes. Lastly, links to the appropriate sections of the ICEB's manuals are available on hundreds of Braille codes. This feature allows you to go right to the source about how many symbols and contractions can be used. (Aforementioned links are to the ICEB's "Guidelines for Technical Material, 2008 version" and "The Rules of Unified English Braille, 2010 version".)

Those with visual impairments will find the App has been especially crafted for use with Apple's VoiceOver accessibility technology.
