Petralex Hearing aid is a simple app which will automatically adjust to specific features of your hearing. Using the power of your smartphone and latest technologies, you can get maximum sound amplification. You only need a simple headset in order to use it. Initially, you need to calibrate and adjust the app to suit your individual requirements.
Once you are set, you can use the app, in conjunction with wired headphones or bluetooth, to improve your hearing skills and get louder, clearer sound. You may be watching TV or just talking to someone in front of you, the app will amplify the voice for you, just as per your own individual requirements.
Very cool for all of us who have hearing challenges!
