I really love this. I use it not infrequently, though I have run into a particular issue. When trying to play from the multi-tone generator, it keeps stopping the sound. I can't play the audio file on repeat because it launches strangely with play music. So I'm at a loss, I have to keep turning it back on every thirty seconds or so. I looked through the settings and didn't see a way to fix it, so I think it's a bug. Hopefully it gets sorted at some point here.

Jacob, the trial version of the app is limited to 30 seconds of playing. Just upgrade to Pro to support the app and have unlimited play time.
Update: Did my message resolved your problem?

Great app. Multiple tracks, no switching off when screen goes blank, no cracks, pops, no sudden breaks. Like it so much, that i have purchased the lifetime use of the PRO version. But i have a question. As i understand it, apart from generating sound frequency, one can also generate/create sound files. When i choose the option sound files, it tells me that i have non, as i haven't generated any. It tells me to go to presets>generate audio file. The only problem is that there is no such option!?

Hi Marek, thank you for upgrading to PRO to support my work. The preset list is inside the module. Ex: goto "Sweep Generator", than tap on the page icon on the top of the app. Now long press on a record line, and a option menu will pop-pup with the open "generate audio file". This will create a wav file on your device when you press STOP.

Just too many forced adds and way too expensive. The app has good functions but is close to unusable for free and from the comments the paid version is also unreliable and not backwards compatable. Use add banners instead of full screen video ads and don't constantly pester the user to buy. Consider having a pay range like a lot of other apps do where the user can choose an amount. The issue is your not adding a huge amount of functions over free apps and then charging a lot for them.

Sebastiann, there is one time pay: (LIFETIME). The app is RELIABLE, and the PRO version is the same code. Banner ads give developers zero income. You just want this app for free, and no ads, like many users. Did you get your expensive phone for free? Don't write about things you know nothing about.
