MultiBit app for iPhone and iPad

MultiBit is a new type of vision test that was specifically devised for self-testing by patients under medical care for retinal disease. The app requires registration by the patient’s caregiver.
The MultiBit flashes sets of test digits that are built up by varying numbers of pixels. The test task is to spell out what digits were shown. When the test is completed, the recorded answers are played back to allow self-scoring of results. The results are automatically transmitted to the caregiver. The app is developed by experts within the field of Ophthalmology.
