Bluetooth latency on iOS has been a known problem for years. TakeOne solves it with an Objective Chirp calibration that measures round-trip delay (typically 230-310ms) and aligns playback automatically. 99% first-attempt success rate.
What's in 1.1.0: one-tap calibration, aligned playback and M4A export, three-track Layered Takes (Pro), built-in metronome and tuner.
Everything runs on-device. No account, no cloud, no uploads. Free to download, Plus and Pro are one-time purchases.
