BlackBox vs Hi-Q MP3 Voice Recorder: Compared

Hi-Q details checked Oct 25, 2026 against its store listing
Short answer

Hi-Q MP3 Voice Recorder records high-quality MP3 (up to 320 kbps) on Android, with widgets, mic selection, Wi-Fi transfer and automatic Dropbox and Google Drive upload — but the free demo stops each clip at 10 minutes. BlackBox records all day or on a schedule on Android and iPhone, in compact hourly files that are transcribed on-device.

We make BlackBox, so read this as informed rather than neutral. Every Hi-Qdetail 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 Spot something out of date?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 Hi-Q users complain about

Themes from 1–2★ Google Play reviews of the Hi-Q demo we read in October 2026, paraphrased.

The 10-minute demo limit

By far the most common complaint: people install it expecting a full recorder and find each clip stops at 10 minutes. The listing does state this.

Files moved into a private folder

Since recent updates, reviewers say recordings live in a private app folder that file managers can't reach, and the default save location can no longer be chosen.

Crashes and silent widget recordings

Some report crashes on newer Android versions and occasional silent recordings started from the widget.

When to pick Hi-Q instead

  • You record music, rehearsals or concerts and want high-bitrate MP3 or FLAC.
  • You want to pick the front or back microphone and adjust input gain while recording.
  • You want home-screen widgets and a discreet recording icon.
  • You want Wi-Fi transfer to a PC and automatic Dropbox or Google Drive upload.

When BlackBox fits better

  • You record speech for hours — BlackBox's 32 kbps AAC is about 14.4 MB per hour, a tenth of 320 kbps MP3.
  • You want recording to run all day, or start and stop on weekday and weekend schedules.
  • You want hourly files, daily archives and on-device transcription.
  • You also use an iPhone.

Frequently asked questions

Why does Hi-Q stop recording after 10 minutes?

Its listing says the free version records up to 10 minutes per clip and the Pro version removes the limit. BlackBox doesn't cap recording length — it keeps recording in hourly files while your phone allows background audio.

Which sounds better?

For music, Hi-Q's high-bitrate MP3 and FLAC will. BlackBox is tuned for speech: 32 kbps mono AAC at 16 kHz, which keeps a 24-hour day around 346 MB.

Is Hi-Q MP3 Voice Recorder on iPhone?

We only found it on Google Play. BlackBox is on both the App Store and Google Play.
