TakeOne 1.9.7 — automatic Bluetooth latency compensation & a Practice Band that follows your song

Two months after launch, TakeOne has grown from a one-tap calibration tool into a full practice companion. Version 1.9.7 is live now.

What's new

Automatic latency compensation. Calibration was one tap before — now it's automatic. TakeOne measures your Bluetooth round-trip delay with an Objective Chirp (16 short sweeps through the iPhone mic), then keeps playback and export aligned automatically. One calibration per output; switch headphones and you stay in sync.

Layered Takes — a full arrangement in one take session (Pro). Record a rhythm part, then layer a lead over it, add a vocal — each new pass locked to the same compensated timeline, no manual alignment. Re-record any single track without redoing the session, or export the mixed result as one shareable file. No laptop, no audio interface, no GarageBand project setup.

A Practice Band that follows your song. Enter your song's chords once in Song Sketch. Drums, bass, and pad play your actual arrangement — verse, chorus, and bridge each get their own feel. 1.9.7 makes the band more musical: warmer bass, fuller pads, and drums that shift subtly between sections.

Loop any passage. Select the bars you keep stumbling on and loop them until the part feels right — the band keeps time around you.

Everything runs on-device. No account, no cloud, no uploads. Free to download; Plus and Pro are one-time purchases.

I built this because I practice guitar late at night with Bluetooth headphones and wanted playback I could trust. Happy to answer questions about the audio engine or the solo-development journey.
