## What is GrooveLinker?

A skill-building app for analog DJs.
It listens to your real decks through the microphone, rates both the technique and the song choices you cannot hear yourself, and tells you what to drill next.
Put your iPhone in front of the decks and start blending real records.
The microphone picks both records apart and measures your beatmatch down to the millisecond.

= FOR PEOPLE WHO PRACTISE ON REAL DECKS
GrooveLinker is the other kind of DJ app. It listens through the microphone to the real turntables
and mixer in front of you, measures how far apart the two records are, and scores it.
No audio files needed. Nothing is recorded.

= FOUR NUMBERS THAT SHOW WHAT IS LOOSE
- Match: beats taken to lock in after you brought the second record up (full marks within 16)
- Hold: how much the BPM gap wobbles through the blend (full marks at 0.2 or less)
- Drift: how many milliseconds you slip per 32 beats (full marks within 20 ms)
- Phrase: how far off the top of the phrase you dropped it (full marks at 0)

= LIKE A DJ SCHOOL, IT GIVES YOU THE REASON AND THE NEXT MOVE
Not just a number. When your Drift is weak, it reads like this:
"+38 ms per 32 beats. The BPM gap is near zero and the slip still grows, so a tempo difference
too small to hear is stacking up. After you lock in, check the kicks every 16 beats and
move the pitch 0.1% toward the slip."
The fact, the cause, the drill. All three, every session, for each of the four numbers.

= PRACTISE WITHOUT GEAR, BUT THE ANALOG WAY
There are two turntables and a mixer inside the app. What there isn't: a sync button.
No waveforms, no cue points. You get a needle, a platter, a pitch fader, three-band EQ and a crossfader.

- Cue by holding the platter with a finger and rocking it until you find the kick
- The needle lands wherever you tap the record strip
- Switch between 33 and 45 rpm
- The strobe dots on the platter rim stand still at 0% pitch
- No BPM and no ΔBPM while you practise. The numbers come after you stop

= RECORDS WANDER. SO DO TURNTABLES.
A real record cut from a live drummer moves 1 to 2 BPM inside the track, pushing in the main
section and sagging in the breakdown. The ten records the app builds reproduce that wander
(house and techno hold steady, being drum machines; disco and hip hop move, being bands).
You can pick the deck too: a fresh direct drive, a well-used club deck, a belt drive. Each wanders differently.
Matching once is not the point. Staying matched is what analog is about.

= ONE PAIR OF EARPHONES, THE ONE-EAR-CUP FEEL
An iPhone has a single audio output. So plug in earphones and the app splits them:
headphone cue in the left ear (the record you brought up), speakers in the right (what the floor hears).
The same feel as holding one cup to your ear on real gear.

= BRING IN YOUR OWN RECORDS
Plug a USB audio interface or a USB turntable into the iPhone and record at line quality.
The app reads the BPM and key, maps every beat with its wander, and loads it onto a deck.
The iPhone microphone alone is plenty for beat practice.

= THE DJ YOU WANT TO BE CHANGES THE SCORING
Club floor, hip hop turntablist, bar selector, open format,
radio mixshow. Your choice reweights the four numbers and rewrites the 18-step path.
Long club blends lean on Hold and Drift. Quick turntablist cuts lean on Match and Phrase.

= IT PUTS A NUMBER ON YOUR SELECTION TOO
For two imported records it rates how well they fit, on tempo distance and Camelot neighbours.
It will not tell you a record is good. Only whether the two can sit together.

= PRIVACY
- Microphone audio is analysed on the device. Nothing is stored or sent
- No sign-up. Your practice history lives only on this iPhone
- Track ID uses ShazamKit: only a signature reaches Apple, never the audio

= PRICE
Free: three score checks a day.
Free covers the first 3 steps. Pro (monthly or yearly): unlimited score checks, all 18 steps, weekly review and backups.

## Version history (last 4 releases)

### 1.3 — 2026-09-23

The skill radar on the Review screen never moved, however much you practised. It does now.

Nothing ever recorded the level-one skills — the pitch fader, dropping the needle, counting bars — and the radar reads the rungs in order, so it stopped at the bottom one. A hundred-point session left all six areas at zero. A session that produced a measurement now records what it plainly demonstrated. Last week's outline is counted from the sessions themselves rather than from when a skill was last touched, so re-earning a skill today no longer deletes it from last week.

Settings has a new checklist, "What you can do now". Mixer work, selection, playing out — the parts no microphone can grade. Ticking them fills in the radar, where four of the six axes could never move.

Also in this version:

• Clearing step 3 said "the next step is open". Step 3 is exactly where the free plan stops, so it now says what actually happens.
• Some strings appeared in Japanese in English, German, Spanish, French and Italian: the BPM readout on the live scoring screen, the purchase messages, the recorder's input name, and four others.
• The scoring thresholds were called two different things on two screens that sit next to each other. One name now.
• Ear training: the card said to listen again before moving on, over a replay button that could not be pressed.
• Ear training: when the audio could not start, the only way out was the door. You can retry now.

### 1.2 — 2026-09-20

Ear training, and it needs neither records nor a microphone.

Two records play together and you say whether the second one is running fast, slow, or matched. Six of eight clears the rung. The gap starts at 3.0 BPM and narrows to 0.3 — the same gap this app's scoring calls matched.

Noticing that a mix is off and knowing which way to fix it are two different skills, and it is the second one you need standing at the decks. So the answer is faster or slower, not just wrong. Two of the eight are already matched, because leaving a good mix alone is practice too.

It opens from the TOP tab, and every rung is free.

### 1.1 — 2026-09-18

Now you can hear what "matched" sounds like before you practise.

On the first screen, tap "Hear what matched sounds like first" and two records play at the same tempo. Flip the switch and one of them runs 0.9 BPM fast: the single kick splits in two and the gap keeps widening. That gap is what the score is measuring. The records are generated inside the app, so there is nothing to download.

The wording throughout the app has been reworked as well, so lines break where a sentence does rather than wherever the screen runs out.

### 1.0 — 2026-09-16

No release notes.
