Voice Tools: Pitch Tone Volume is a free Android application developed by DevExtras under the Lifestyle category, specifically Medical. This app functions as a voice recorder tool for transgender voice therapy. It provides visual feedback on the voice pitch, phonetically balanced sentences for reading, and tones of specific pitches to mimic. Users can record and playback without saving files to their device, and it also offers real-time volume analysis. It is designed to be used for about 5 minutes a day over several months as part of voice therapy.

This app is not a substitute for voice therapy, nor does it change the pitch of the user's voice. The voice pitch analysis feature works best with an external microphone. The app is available in two versions: a free, ad-supported version and a paid, ad-free version that can be unlocked via an in-app purchase in the settings screen. The app does not save or share any voice recordings, ensuring user privacy.

Users can help the developers improve the app by reporting any bugs or suggesting improvements via email.
