BSL Sign & Spell takes the user through each letter of the alphabet, with the help of two videos showing the front and side view of each sign. This makes learning easy, and a quick quiz after every few letters means the learner can check their progress. The app is a brilliantly handy tool which lets learners of BSL revise their alphabet anywhere, at the touch of a button.
