Phonal Tonal

Not functional, does not work and yes i know what a blue box is and what it does but the tones are not good, no wonder that they are not accepted.

Love the product - have had this app for many many years. As a telecom technician and later engineer, I can decode/identify DTMF by sound, but I have not mastered MF. Would you consider adding MF decode? I would gladly buy the app over again to get this feature? I want to be able to decode MF streams as well as DTMF using the microphone. Thank you!

Wow, this app is GREAT!!! However along with an update came the delay in dialing quickly. Prior to my upgrade I could tap out a 13 digit number in a few seconds, now it takes Much more time. Also on my older iPhone it has now stopped working altogether and I know the update will not be happening on the old phone. Please make a few changes to allow older iPhones to continue using this app without have to also buy a new phone. Thank you!!!

I regularly troubleshoot PSTN interfaces for digital PBX systems, and this is exactly what I wanted and more!

I’m a telephony / collaboration engineer. been doing this stuff since before tone dialing was prevalent. This app is Solid. Simple. Does what I need PLUS more. Takes me back to the 90’s! Love it. Worth it.

I just wanted a DTMF keypad with the ABCD keys, and got so much more. This has miscellaneous standard signaling, international tones, and even the various hacker box tones like the famed blue box! Yes I know those don’t work anymore but it is fascinating to play around with. For $0.99, this is a bargain. Hope the price stays the same because it will undercut the competition with an arguably better app.

I’ve used this app for a little bit on Project MF and it works just like it should! Any of the MF tones I play, Project MF perfectly recognizes them. Now, the only issue I have is that on the iPad version, under miscellaneous, the Dial Tone (special) actually plays the busy signal instead. Something very VERY minor, but I just thought I’d bring it up.

Absolutely fantastic! I purchased the app sight unseen based solely on the reviews. The only thing extra I would like to see is an information page that shows the frequency components for all the app is capable of making. For example: 1 - 1209Hz & 697Hz 2 - 1336Hz & 697Hz * - 1209Hz & 941Hz # - 1477Hz & 941Hz (and so on...) Thanks again!!

I hardly ever write reviews but you absolutely rock!! I’ve had this app ever since it first showed up...long longtime ago... in another univ....... Tonight, I was culling apps off the phone when I noticed you didn’t have that little 64bit/death next to the icon... tapped the app and my happiness resulted in my five star, two thumbs up review 👍👍 Thanks for staying relevant when many have given up 🖖

I like this app. But what the is it white e ui
