Works great
First: If you’re having trouble with this app… be sure to slide the switch on the side of your phone to in-mute it. If your phone (or iPad) is muted, it can’t generate nor decode audio.
To the developer: Great UI design. I’m using this in my telephone systems class and it’s great.
Thanks for writing such a great app.

I second “app name misleading”
If only the author could get the correct tone matrix for the Blue Box.
Wikipedia and other sources have the list of tones required. It should be easy to fix.

Does not work for me
Unfortunately this app does not work for me. After switching from dial to listen back to dial the output seems to be muted. Need to restart the app to regain output again. Listen mode only picks up noise, but no actual tones. Tried to adjust settings, but it got only worse. Installed a different app to decode tones which worked out of the box.

All the tones you need
Idk why this didn’t work at first. Without updating it now works. Sorry for the poor initial review!
For those who know what this is
I'm really happy and very surprised that this exists. Works very well. Only phone phreaks know what this is really used for, or what it used to be able to be used for.
Perfect
I've had this app for years now. Working in the telecom industry it has proven highly valuable.
Not decode
Decode not the true tone
Real signal gen
I have tested this with MC145436 DTMF decoder and LM358 used for condenser microphone preamp. If you are using an electronic hardware decoder this is the DTMF keypad you want. Most are playing back recorded samples, whereas this one is using low level audio framework to generate signal. The iPhone speaker begins to clap out at about half volume for DTMF. Works most reliably for me at about half volume for iPhone5.

Listenback is not working
Either it is incomparable with the iPhone 5, or iOS 6, but the decoding feature, which is the only reason I bought it (who needs to listen to dial tones?) is not working. I read all the trouble shooting methods, but it is obviously a version issue. Will be slightly less of a waste of money if they ever update it. Still don't know if its worth 3 bucks just for a decoder, but I needed one for work, and had to have it. What a let down.

Really Nice App
I came across this app while looking for a simple DTMF keyboard app to play DTMF tones and one ideally that had the ABCD tone combinations too. Several free apps were no good. This one came up in the search results for £1.99. No ratings or reviews as yet, but it's looks stood it apart from the free apps so I risked it.
It does everything I wanted plus more.
Key features that I like.
1) In dial mode the tones last as long as you hold the button.
2) Includes A B C & D buttons.
3) CUSTOM allows you to set up your own tone pair.
4) The keyboard looks like a real pay-phone keypad rather than bland set of buttons that have had no thought put into them.
5) DTMF decoding function. I didn't even know it did this when I bought it. I already had 2 DTMF decoding APPS on my iPhone but this is much better. The others have been deleted now. It's great to have an all in one DTMF app.
This app is clearly written by people who have a passion for the subject.

Ver. 3
Nice additions to Version 3. This is a really nice app and brings back fond memories.
Perfect.
Update is great! I wanted a portable bluebox to use with project MF and I got one great job!
ok!
una vera blue box :)
App Name Misleading
Back in the late 60's and 70's, when AT&T deployed #5 Crossbar switching systems, Blue Boxes were used to emulate the in-band signaling needed to route long distance telephone calls and "surf" the dark unexplored recesses of the long distance telephone network.
#5 Crossbar was phased out and replaced with SS7's "out of band" signaling in the late 70's through early 80's rendering the blue box an impotent artifact of ancient history. Nevertheless, the novelty and folklore of the devices continue to persist.
I would have liked to have rated this app 5 stars, but had to deduct 2.5 stars because the app name erroneously lead me to expect a DTMF encoder that actually emulated the tone matrix of a true "Blue Box" on the iPhone. When the author includes the correctly tuned matrix in the app I'll update my rating. There's no longer any applicable reasons not to (and haven't been for almost 3 decades).
I also had some difficulty with the decoder and subtracted a half point for failing to buffer the touch tone strings detected by the software to work around the frequency detection / number identification issues.
Otherwise, the app does everything else it claims, and the ability to adjust pulse and interval lengths was a nice touch.
Please fix the frequency encoder and allow the user to switch between Blue Box DTMF and "standard" DTMF.

Works well.
Suggestions for a few improvements and additions: For BUSY and RINGBACK, fix (or option) so press and hold to get continuous standard intervals for each signal. Most of all, give me the alternate tone set to provide for *real* bluebox tones including KP and ST. No harm in providing these since they can no longer be used to defraud the system. They're just so melodic! Thanks.

Garbage
Don't waste your money
No good
Non molto preciso, ha bisogno di un settaggio macchinoso
Save your $
The software seems easy to use, but doesn't work. Downloaded a different app for decoding, and worked great! Would NOT recommend this.
