English listing
Short description
Generate tones, explore waveforms, run frequency sweeps and export WAV files.
Full description
Explore sound with sine, square, sawtooth and triangle waves. Set a frequency, choose the output channel, adjust volume and run a frequency sweep. Save presets, select musical notes, set a stop timer and export a generated WAV file.
Generation and settings work on your device without an account. English, Romanian and Spanish are available. Actual audible output depends on your device, speakers and headphones.
Start at a low volume and keep listening sessions comfortable. This app is not a hearing test, medical treatment or calibrated measurement instrument. Published by Praxis Science Lab.
Data safety worksheet
Candidate: no off-device app data collection or sharing found in the reviewed implementation. Local-only processing is different from collection in the Play form. Verify the exact signed package, included SDKs and every active release before submitting.
Generator settings, language, presets and the last generator state are stored locally. Audio is synthesized on your device. Exported WAV files are written to a destination managed by the device. The app has no account, advertising SDK, analytics service or application backend and does not upload presets or generated audio to Praxis Science Lab.
The Android release does not request microphone access. A legacy write-storage permission is limited to Android API 28 and below for WAV export. Newer Android versions use the platform's file/media facilities. If you open or share an exported file with another service, that destination handles the file under its own policy.

Capture at least two authentic screenshots from the final app. Do not use simulated screens, synthetic medical fixtures or old-brand captures. Screenshot language must reflect the actual app; English captions do not imply an English-only interface.
Actual Android test-build captures, prepared for listing review. Recheck against the final upload build.
Remaining release checks
- Recheck screenshots against the final signed AAB and inspect merged permissions, legacy export and physical-device audio behavior.
