Does what it says, except for one thing: "dial a contact" errors because it doesn't have contacts permission, but the app never seems to prompt for said permission. It must be granted manually via app info, which not everyone would probably think to do. Edit: Thanks for getting back to me so quickly. With the August 11 update, the app functions pretty well perfectly!

Probably a reflection of the age of the app; it's from before that behavior was adopted. I'll look into getting it up to date with that way of doing things.

Excellent app concept and design but has several major bugs. Tones shift in pitch over time, preventing receiving equipment from recognizing the tone. Interference is heard when playing multiple tones together. On my phone, accessing the DTMF dialer causes the app to crash entirely. But again, love the concept and the features the authors included.

Just pushed a new release (build 18) that should address the frequency shifting issue. If you're still experiencing problems after that, feel free to drop a bug report on the GitHub repo and I'll see what I can do. Provide as much detail as you can.

Works great, although I do have 'clicking' on start and end of audio samples on Galaxy S9+ needs a couple milliseconds of fade-in / fade-out. Thumbs up šŸ‘
