Impressed yet disappointed

So I stumbled upon Dectone through Petralex. initially I was impressed by how thorough you can be but after my sound test I went to test out what I put together and I was told to pay to be able to use the sound profile.

A proper trial period would be amazing or at least a heads up that the hearing test is free but the rest requires a paid subscription.

Wonderful App This App lets you test your hearing, allowing you to create different hearing profiles so that you can then use the App as a hearing aid in different environments. Sensible and wonderful. I can now hear without spending thousands (which I don't have) on hearing aids. Thank you very much for your great work. Sadly it did not work with my Samsung neo but I bought a IPad and it works perfectly with that.

Top of the line I am partially death from a sinus issue, I have not been able to hear for a while now. I took the hearing test on this and it's right on point to an actual one, so glad I found this app works beautifully. No mic feedback like other apps, this ones is just perfect!!
