The Red Lion app was created for Sound Communication, which is a hearing aid fitter and vendor based in Ontario. The app is meant to combine hearing and seeing. It is said to be the "hear what you can see app" because it is a hearing tone test with a photo.
Users see a blurry image and once they hit the button indicating they can no longer hear the sound, the image will be as clear as it can get in that time frame. If the photo is still blurry, the original crystal clear image will appear on half the screen and the image that corresponds with your hearing will appear on the other half. This is an indication on how well you hear. It gives you the option to be directed to a website that encourages the user to book an appointment to get further checked once they receive their results.
