Terrence Phillbert

A very well thought out audio test app. Developer is responsive. Edit: still my favorite signal generator app 7 years later! Quality product. Edit 2: I purchased in 2013, so I've been using this signal generator for 11 years now. After purchasing, I needed an inverted polarity noise signal to detect speakers with incorrect polarity wiring. To this date, this is still the only app that does this. Indispensable IMHO. It's worth the price for the pro version.

I try a free version and it is good. I use programable option and it is only allow me to run 660 second. It said due to my phone memory. If I buy pro version, can I use about 3,600 second (1 hours)without buying a new phone? If yet, I will buy pro version and give you 5 stars. Please help me with an answer. Thank you.

Not a bad app and is probably the only app that lets you build custom tones (useful for piezo emulation). However, I'd be more than happy to pay for the app if 1). developer gets rid of the forced app update enforcement, and 2). add FM modulation with Frequency and Amplitude adjustment parameters.
