Chirps is now available on the App Store for iPhone and iPad.

After months of design, testing, field use, and refinement, Chirps has officially been approved by Apple and released on the App Store.

Chirps is a bioacoustics field companion built for real-time listening, viewing, recording, and review. It brings together a live spectrogram, waveform display, audio monitoring, WAV recording, offline playback, and export-ready visualisation tools in a single mobile workflow.

The app is designed for field researchers, bat surveyors, birders, nature recordists, students, and anyone who needs a practical acoustic tool away from a desktop setup.

With Chirps, you can:

  • view live spectrograms and waveforms directly on iPhone and iPad
  • monitor incoming sound with passthrough or heterodyne modes
  • record uncompressed WAV audio in the field
  • review recordings inside the app with offline spectrogram and waveform views
  • export high-quality spectrogram images for reports, teaching, or publications
  • work offline without accounts, tracking, or third-party data collection

A core goal of Chirps has been to keep the experience focused and dependable: no account setup, no remote backend, no analytics pipeline, and no requirement for an internet connection during normal use. The app is built to stay close to the work itself.

Chirps will continue to evolve through real-world use, testing across devices, and feedback from people using it in genuine listening and recording workflows.
