This app in only available in the Google Play Store. If you are reading this on another site, do not download the app, it may be an old version, and is not authorized by me. Go to the Google Play please.
- In-app purchases: this permission allows users that want to support the future development and maintenance of this app to upgrade to PRO VERSION, paying a small fee, and without installing a new separate version. This process is the new trend in phone apps. This is a one time purchase only.
- Internet access: This is used only by Google Analytics module, so i can better understand what features are being used.
24 KHz is only possible in phones with a 48KHz sample rate DAC. Some very expensive phones do not have such a DAC. This is a hardware limitation.
=decrease graph refresh rate to 10FPS (some android devices are to slow to handle more than that)
This update is only possible thanks to the users that are supporting the development of this tool. Please upgrade to PRO.
