See the device, box contents and first look before you decide
Simple, everyday situations where Halo protects the words, reminders and facts you cannot rebuild from memory.
Phone apps are convenient for quick voice memos, but they crack under professional long-form meeting, lecture and call capture.

Halo protects raw audio without taking over your screen, storage or main phone battery.
Keeps recording even if your phone rings.
Calls, alarms or notifications can crash recording.
Up to 35 hours without using your phone battery.
Constant microphone use drains your main device.
Dual spatial array for clean meeting pickup.
Built mainly for close voice-to-phone range.
Work audio stays separate from personal files.
Fights with photos, videos and phone storage.
The Verdict: A phone app forces your main communication device to do stressful double-duty. Halo is built for single-task text-and-audio reliability.
Explore where Halo removes the pressure to remember everything live.
Capture strategy, objections and commitments while staying fully in the room.
With appropriate consent, review the detail afterwards instead of typing throughout.
Return to exact wording before writing the follow-up or proposal.
Capture lectures and turn long recordings into usable study material.
Recover decisions, owners and deadlines before producing the next action.
Missed decisions, forgotten actions and lost ideas all begin the same way: the detail disappears before you can use it.
Turn conversations into named owners, tasks and deadlines before the meeting disappears into memory.
Listen properly now, then review the detail afterwards where recording is appropriate and consented to.
Return to the exact concern instead of writing a follow-up around the wrong problem.
Keep the explanation and turn it into useful study material after the lecture.
Capture the thought while it is complete, before the next interruption replaces it.
Record with one dedicated device instead of switching apps and typing while moving.

A rushed note changes the meaning. Return to the exact quote, its context and the next step.
DOWAY helps organise long recordings into summaries, decisions, action items, translation and mind maps.
Search the words and jump back to the part that matters instead of replaying everything.
Capture important conversations and ideas before the detail disappears.

Dedicated recorder with 64GB storage, magnetic phone attachment and one year of DOWAY Max included from activation.
Use Halo properly from day one. The 5-pack helps you capture better recordings, turn them into useful notes and take action faster.
Halo is built around a local-first recording flow for sensitive meetings, lectures and client conversations. Audio is captured to the device's 64GB onboard storage first. You control when recordings are synced through the companion app after QR-code onboarding and Bluetooth connection, so transcription happens only after you choose to process a file. NERALVO does not authorize the use of your private audio for AI model training.
DOWAY Max is included for the first 12 months. After the included year, choose an optional subscription or buy transcription minutes in the DOWAY app when needed.
| Minutes | Transcription time | Current listed price |
|---|---|---|
| 60 minutes | 1 hour | £0.99 |
