About this app

Simple, intuitive, easy DTMF Tone Generator.

I checked all other DTMF tone generator apps, saw that they were all old and buggy, so I made my own version vastly better. It incorporates feedback in the reviews of the other apps. If you have any questions, comments, or suggestions, feel free to email me. I hope you like it.

Description:

Play a tone, any tone. This app is basically two apps in one. One side is a simple DTMF tone generator, and the other side is produce-any-tone-you-want signal generator. You can hear what any frequency sounds like. The help screen in-app also provides the official frequencies for DTMF tones. When playing back recorded DTMF numbers, put your Android phone near the analog telephone's speaker so that you can dial through your PSTN (Public switched telephone network) phone.

Features:

1. DTMF specific tones

2. Ability to save unlimited DTMF tones for common use (and change playback time for tone and pause)

3. Proper playback for recorded numbers so that you can dial by clicking a single button

4. Ability to play any tone in the second app page.

5. No permissions required! No ads!

6. Easy share if you like it!

Background:

Hi, my name is Danial Goodwin. I am a developer who creates many different applications. I love working on them, making them better, and providing features users didn't even know they wanted yet ;). But, unfortunately, I don't have time to keep updating every single one of them. The good news is that I love getting feedback about my apps AND the more feedback I get about a particular app, the more likely I am to update it, especially if many users request the same feature. =]

More technical info:

DTMF Tone Generators allow Dual-Tone Multi-Frequency (DTMF) signaling which allows machine control remotely over standard telephone lines. Some HAM radio operators use this too.

DISCLAIMER: This app is not meant to be for everybody. Development work going into this app will be for the small percentage of people that do like it. ;)
