Holinature is the personal headquarters for eco-defenders, naturalists and citizen scientists. Capture climate, vegetation, soil, soundscape and biodiversity readings — then dispatch a signed evidence dossier to the right authority in two taps.
Every panel runs as an independent stream. The PDF you generate carries every reading with its timestamp.
Temperature, humidity, pressure and air quality, sampled at 1 Hz with status-aware highlights.
Spectral health proxy with PAR irradiance overlay so you can correlate canopy stress with light dose.
dB SPL with a live equalizer — flag man-made noise intrusion in protected zones.
Moisture and water-table depth, visualised as a vertical column gauge.
Sun elevation, sunset countdown and lunar phase — knows the right moment to capture.
Shannon-Wiener H′ with species-pip visualisation. Add to a session to track recovery.
Precise location with reverse-geocoded address, bound to every reading you save.
Signed PDF dossiers, pre-routed to the closest environmental authority for your region.
Holinature stores observations on-device. Push notifications use OneSignal with anonymous device IDs (IDFV). No IDFA, no advertising trackers, no user tracking under App Tracking Transparency.
