Late-night guitar with Bluetooth headphones on.
You want the click in your ears, not in the room. TakeOne keeps the practice quiet while the iPhone mic captures the instrument more naturally.

Who it is for
For the practice moments that usually disappear.
TakeOne is for musicians who do not need a production session every time they practice. They need a quick way to hear the count-in, record the room with the iPhone mic, review the current take, save the useful ones, or layer a few tracks when practice needs more context.
A quick vocal pass before the idea fades.
You need to hear the pulse, sing the phrase, and know whether this pass is worth keeping. TakeOne turns that into one short loop.
Count-in · record · play back
One useful take to send or revisit later.
After a real practice round, export the current take as M4A for feedback, use Plus to build a saved library, or open Song Sketch and practice it with a full band behind you.

Why Bluetooth gets weird
Your headphones are for listening. The take still needs a clean input.
Bluetooth practice is convenient, but it can blur two jobs that should stay separate: monitoring the click and recording the performance. TakeOne keeps that route visible, then aligns playback and export after calibration.

The raw take keeps its count-in. The playback/export timeline applies the measured offset.
The other problem
Practicing alone gets old fast.
A metronome keeps time but keeps you cold. Drums, bass, and pad can change that. TakeOne builds a practice band around every song you play — verse, chorus, bridge all get their own arrangement. You’re not just practicing with a click, you’re playing with something that sounds back.
The 1.6 practice loop
How TakeOne helps during a real practice take.
Version 1.0 focused on one thing: getting the audio right through Bluetooth. Version 1.6 adds the band — Song Sketch remembers your chords, and drums, bass, and pad play along. The route, calibration, and recording layer hasn’t changed; now there’s something worth playing along with.
Set the route
Confirm the output you are listening through and the microphone used for the take.
Calibrate output once
Measure the delay for the current headphones, speaker, AirPlay route, or interface.
Record with a count-in
Hear the pulse before the take starts, then play through without managing extra tools.
Keep the useful one
Play it back, export the current M4A, save it to Plus, build a three-track Layered Take with Pro, or practice it again with the band arrangement from Song Sketch.

TakeOne Pro
Pull out your phone and Bluetooth headphones. Start layering in seconds.
A musical idea hits. Grab your iPhone, put on your Bluetooth headphones, and open TakeOne. Record a rhythm part, layer a lead over it, add a vocal — all in one take session, all perfectly aligned by latency compensation. No laptop. No audio interface. No GarageBand project setup. When you are done, export the mixed result and hear how it all fits together.
No DAW. No cables. No waiting.
No waiting for a laptop to boot up. No adapter for wired headphones. No DAW project to set up. Just your instrument, your phone, and the idea — captured and mixed in one session.
Record the bed.
Rhythm, chords, or a guide part — the count-in is already set, your route is confirmed. Press record.
Layer over it.
Hear Track 1 in your Bluetooth headphones while the iPhone mic captures the next pass. No manual alignment — done automatically.
Hear the mix.
Add a vocal, lead line, or harmony — then play back all three tracks as one mixed take. Export and share.
Track control
Re-record, mute, adjust volume, or nudge a track when the practice pass needs a small correction.
Mix export
Export the layered mix as a shareable result instead of sending three separate fragments.
Clean video
Create a cleaner share asset for a layered take when the practice deserves to travel.

1.6 · Practice Band
Your practice band follows every song you play.
Tell TakeOne what song you’re working on — the chords, the key, the tempo. It builds a custom band around that song. Drums, bass, and pad that change with each section.
♪
Song Sketch
Type in the chords once. TakeOne remembers the key, progression, and structure — one less thing to think about when you sit down to practice.
≡
Practice Band
Drums, bass, and pad that play your song. Each section follows the chords you entered — verse, chorus, bridge all sound like the right part.
◉
Loop Practice
Stuck on a tough section? Loop it. Repeat specific passages until they feel right, while the band keeps time around you.

Before vs after
See what latency compensation sounds like.
The same recording, with and without TakeOne. The difference is in the alignment — not the performance.
Without TakeOne
Misaligned playback.
↔ offset: 100–300ms
Bluetooth latency pushes your recording out of sync. You can't tell if you're actually improving.
Can't trust what you hear
With TakeOne
Perfectly aligned audio.
✓ < 5ms residual error
TakeOne compensates in real time. What you hear back is exactly what you played.
Practice with confidence
What it includes
Practical advantages for everyday practice.
Every feature earns its place in the practice room: better input, clearer timing, less setup, and a band that plays along.
Your tuner, metronome, and recorder are usually three separate apps. In TakeOne they share the same timeline — because tuning, setting tempo, recording, and layering was never four jobs. It was one practice session.
Cleaner input
Keep listening through your selected output while aiming the recording at the iPhone mic.
Synced judgment
Calibrated playback helps you judge the take against the metronome instead of Bluetooth delay.
Fewer interruptions
Count-in, metronome, route check, recording, playback, and export stay in one practice loop.
Practice Band
Drums, bass, and pad that follow your song. Practice with a band, not a metronome — Song Sketch remembers your chords, and the band plays along.
TakeOne 1.6
TakeOne is now available on the App Store.
TakeOne is a free iPhone app with optional TakeOne Plus and TakeOne Pro one-time purchases. No account required, recordings stay local unless you export or share them.
Plain answers
Before you use TakeOne.
Who is TakeOne for?
Musicians who practice with headphones and want a quick way to record, hear, keep, or export one useful take.
Does TakeOne upload recordings?
No. TakeOne stores recordings locally on your device unless you explicitly export or share a file.
How accurate is the calibration?
TakeOne measures round-trip Bluetooth latency with sub-5ms precision using an Objective Chirp. All signal processing is on-device — nothing is uploaded to any server.
What should I try first?
Use the headphones or speaker you normally practice with, calibrate once, record a 30-60 second take, then play it back or export it.
What do TakeOne Plus and Pro unlock?
TakeOne Plus unlocks the saved-takes library, saved-take management, Recently Deleted recovery, Clean Export, and Clean Video. TakeOne Pro includes Plus and adds three-track Layered Takes, mix export, Clean Layered Mix, and layered Clean Video.
Does it require Bluetooth headphones?
No. The product is built for Bluetooth practice pain, but it can also work with speakers, wired routes, or other selected outputs.
Can I practice with a backing band?
TakeOne 1.6 introduces Practice Band — drums, bass, and pad that follow the song you’re working on. Enter the chords once in Song Sketch, and the band follows your tempo and structure. Verse, chorus, bridge each get their own arrangement based on the Energy Map you set.
Do I need to know music theory to use Practice Band?
Just the chords of the song — which you probably already have if you’re practicing from a tab or sheet. Song Sketch lets you type them in, and TakeOne handles the rest: key detection, chord voicing, and automatic arrangement.
