BlackBox vs Dolby On: Music Recorder vs All-Day Recorder
Dolby On is a music and video recording app that applies Dolby noise reduction, EQ, limiting and spatial audio to what you record, then helps you share it. BlackBox is a voice recorder for long days: it records in the background all day or on a schedule, files each hour separately and transcribes on-device.
We make BlackBox, so read this as informed rather than neutral. Every Dolby Ondetail below comes from its own store listing or help docs (linked in References); where a listing doesn't say, the table says so rather than guessing. Spot something out of date? Tell us.

What Dolby On users complain about
Themes from 1–2★ App Store and Google Play reviews of Dolby On we read in October 2026, paraphrased.

Some Android reviewers describe recordings disappearing with no recovery folder.
Source: Google Play reviewsProcessing that doesn't suit voice
A few reviewers say the automatic enhancement muffled their recordings, and that they can't choose the saved file type.
Source: Google Play reviewsWhen to pick Dolby On instead
- You record music — songs, rehearsals, gigs, instruments — and want it to sound finished straight away.
- You want automatic noise reduction, de-essing, Dynamic EQ, compression and limiting without a studio.
- You record video as well as audio, or want to share straight to SoundCloud and social apps.
- You want to import recordings from other apps and enhance them.
When BlackBox fits better
- You're recording speech — meetings, lectures, your day — rather than music.
- You want recording to run for hours or on a weekday/weekend schedule.
- You want hourly files, daily archives, and transcripts you can search.
- You want everything kept on the phone with no account, behind Face ID or a passcode.
Frequently asked questions
Is Dolby On good for recording meetings or lectures?
Dolby's listing is aimed at music, video and creators; it doesn't describe long background recording, schedules or transcription. For hours of speech, BlackBox is built for the job.
Can BlackBox enhance audio like Dolby On?
No. BlackBox records speech efficiently (32 kbps mono AAC) and focuses on capture, organisation and on-device transcription, not studio effects.
Are both on iPhone and Android?
Yes — both apps are on the App Store and Google Play.
