About
Remember what matters.
NERALVO builds focused technology for people whose work depends on remembering the detail.
Why we built Halo
Notebooks can pull you out of the conversation. Phones add distractions. Halo was created as a dedicated voice recorder that lets you stay present while preserving meetings, lectures, interviews and ideas where recording is lawful and appropriate.
Use Halo on a desk, carry it in a pocket, or attach it magnetically to a compatible phone with the included ring.
What Halo does
Halo records to its built-in 64GB storage for up to 35 hours per charge under stated operating conditions. Supported Halo hardware can connect directly to the standalone NERALVO mobile app for NERALVO-supported Bluetooth, recording, transcription, notes and AI-assisted workflows.
Optional DOWAY Max bonus
Eligible Halo purchases can also include one year of DOWAY Max from activation. DOWAY is a separate third-party service with its own terms and privacy practices. It is an optional hardware bonus and is not required to use the NERALVO mobile app.
How we publish guidance
The NERALVO Editorial Team publishes practical guides about AI voice recording, transcription, meeting notes, privacy and responsible use. We prioritise primary sources, distinguish manufacturer claims from verified facts and state clearly when NERALVO has a commercial interest in a comparison.
