Simply DTMF Tone Generator
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 tones2. 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 button4. Ability to play any tone in the second app page.5. No permissions required! No ads!6. Easy share if you like it!
FAQs:Q: What are all the pause and play times?A: By default, recorded playback transmits signaling rate of 93 ms per tone with 40 ms between tones. Pause characters are 1 second.
Q: What does DTMF stand for?A: Dual-tone multi-frequency signaling.
Q: What is DTMF used for?A: Telecommunication signalling over analog telephone lines, aka tone dialing.
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.

I got first 6 dtmf tone gen apps and this was by far best. All make tones but this allows unique tone generation, records tones , pulls from contacts to create tone file of phone #s. And more. No ads or unneeded access in you phone either.
Could you please add the facility to play back a sequence of recorded tones, without making a call? I use this when making conference calls on my Google home and it would be useful to preprogram the 9 digit conference id. I'll happily donate if you add this feature.
Good functionality, but not enough volume out for my needs
once was great now audio level out is so low that its unusable looking for alternate program
DTMF tab produces sound but records don't play back. Galaxy S7 running Android 8.0.
For use with Alexa it needs to be louder, otherwise seems very good.
Great. Works with my Google home and Alexa for speakers phone calls.
Not loud enough. Add greater and it might be useful.
Simply doesn't work, pressing button does not produce sounds
I use it to get passed the menus when calling for free using Google Home.
It does exactly what it says. It simply works!
works without failing..love it
The DTMF dose not play back at all
I am trying to figure out how to use this with my echo. When I long press and call, it just calls the number...no tones.
A clean, clear and very nice app. I use it to dial extensions when making calls with Amazon Echo devices. It works well.
Used the app in conjunction with making calls on Amazon Echo devices. A very nice feature would be able to turn on the speakerphone or the phone speakers in order to have the DTMF tones louder.
no ads, can record sequences and label, can control length of tones and pauses, etc. Exactly what i needed for ham radio systems control. Thank you very much.
The app is ok but 'Records' doesn't work. There's no sound even when everything is turned on.
Makes a repetitive clicking with the tone generator. Is there a way just to get a clear uninterrupted tone?
Would be pretty cool if it had a volume control.
Can call a number from contacts using the phone but can't play it over the speaker
Cannot play back recorded numbers via the speaker.
Works for what I need done. I was looking for an app that will save DTMF codes for my amateur radio repeater, and got it. Works well.
However that tone generator beta, it claims to be able to generate tones up to 100000 hertz. Audible tones peak out at 18000 hertz on a really really good day so not sure what is going on there unless false harmonics are being calculated. Thats part of the reason CDs sample rate is 44000 sps because the frequency range is half the sample rate.
This is very embracing for me to rate this really useful apps 4 out 5. I want to rate it above 5 but as it is highest adding 'Export as WAV/MP3/AnyOtherFormet' option will push me re-rating this grate piece of tool with highest five marks! And again thanks for your effort on helping us free...
Using to program my hearing aids. Ability to set length of pause and tone length is great. Very clever to have thought of inserting comma for silent periods in the programming part. Only thing more that I'd want would be to be able to use media volume OR ring tone volume to control output.
Having got a hands free headset for my home phone I had no way of initiating an outgoing call with it. This app fixes the problem and the link to the phone book is really useful. A handy enhancement would be for the app to pick up any number against a contract entry
I really like how clean and straightforward the app is, and it has a lot of features, but it has audio problems. Maybe it's just on my Samsung S5, but it stutters while dialing, and in the beta tone generation, I hear a regular ticking. Unfortunately, these make it unusable for me. :-\
Developer is right: this app provides functions I didn't know I needed. The interface is clean simple, well thought out. I can't to figure out how to actually use it.
Loved it. Only issue that I have is that it does not show up under the apps installed on my phone and hence I am not able to add it to my home screen to easily find. But great application and use it to punch in code for calling in my conference line from Alexa. Thank you.
