English listing
Short description
Explore live audio spectra, spectrograms and local measurement sessions.
Full description
See sound as a live frequency spectrum and scrolling spectrogram. Inspect the dominant frequency, digital RMS level, minimum and maximum levels, and clipping.
Save local sessions with numerical measurements and export your data as CSV or JSON. Advanced tools include spectrum comparisons, notes, octave and third-octave bands, PDF reports, screen-off monitoring and local threshold alerts.
Spectrum Lab is the evaluation edition of Praxis Spectrum, with advanced tools enabled and no advertising or purchases. The separate Standard edition is designed for free use with advertising and an optional Pro subscription; commercial purchasing is not configured. Neither edition is available on Google Play yet.
Data safety worksheet
Review the exact release artifact, advertising and billing configuration before completing Google Play declarations. Development testing is not a completed Data safety declaration.
Microphone samples are analysed on the device. The app stores session names, notes, settings and numerical measurements in private local storage, not raw audio recordings. There is no app account or developer-operated audio upload service.
Microphone permission enables sound analysis. A microphone foreground service and notifications support explicitly started screen-off monitoring and local alerts. The Lab edition does not request ads or offer purchases.
The separate Standard development edition integrates Google test advertising, consent and Play Billing. Google services may process connection and device information under their own policies: https://policies.google.com/privacy . Local audio processing does not mean that the advertising edition has no network traffic. Commercial subscription verification is not configured.
Media
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.
Remaining release checks
- Configure production signing and prepare final store artwork and screenshots.
- Configure commercial products and validate consent, purchases and restoration for the Standard edition.
- Complete release-specific declarations and Google Play testing before announcing store availability.
