Comments on Hearing Aid Master (Crystal) for Android
★★★★★
Samsung Note 4: This is the first of about 10 Hearing Aid apps that I tried that actually works. There is more delay than I would like, but it seems that all of the apps Record and then Repeat the audio to the Headphones. I have about 25 dB of hearing loss at medium to high frequencies. If I turn the gain up high enough to hear, I get a lot of Echo of the sounds.. ie I hear the same sound repeated.... that is confusing. The echo is weaker than the 'real sound', but it is there. It works with the screen OFF, when you push STOP, and it quits like it should. Quite Unlike the POS Damic which refused to exit, It leaves the Microphone on ALL the time, even if the app is exited.... Also Damic refuses to Uninstall when asked to. I had to Force Uninstall it by removing the app module. I going to give Hearing Aid Master 5 Stars for working with Samsung products, none of the others worked well at all. Only Super Spy and Dacruim provided any audio, but I could hear better with my own ears than their POS apps. Good on you Sennikpro, will use this for a few days, and if it continues to work, will send in a Donation...

Tried at least 8 different hearing aid apps here in google play but this one stands out as the best in sound amplification. Though I like the UI of others with equalizers but they're too weak. Another good one stops when the screen locks. So, I've finally chosen this app. It only lacks equalizer and a volume control while in use. I wish the developer would come out with an update with incorporated equalizer and volume control as the volume control of this version can only be adjusted before using.
★★☆☆☆
yet another with huge delay and echo. junk... yes junk...
★★☆☆☆
While it boosted the TV audio, the delay made it like watching an old chopsaki movie, and my speech was so extreme, it was distorting. I was looking for something so I wouldn't drown out the neighbors while watching TV, and possibly use as an in ear monitor while playing, but the latency on this app makes that impossible.
★★☆☆☆
All fake reviews probably Just gives out loud unbearably static noises...

★★☆☆☆
Silly use of DSP The app misses the point of a hearing aid, it MUST be zero lag. Too much use of un-necessary digital signal processing makes it unusable because of the lag added by the extraneous DSP.
