Description
BeatLock is an iOS metronome that clicks the instant you tap play, with no wait for a full beat. Play a song, tap Listen, and in a few seconds it finds the tempo and where the beats fall, then takes over in time. Nudge the beat earlier or later while it plays without changing the BPM. Beats are scheduled on the audio clock, so it never drifts. Per-device latency calibration (incl. Bluetooth), Apple Watch haptics, and all 8 sounds free.

Could you build this?
Partial Standard metronome sound playback is straightforward, but real-time microphone beat detection, tempo tracking, and sample-accurate audio scheduling require specialized DSP audio programming.
What it would actually take: The application requires an iOS audio pipeline built with AVAudioEngine or CoreAudio at low buffer latencies. The core technical hurdle is implementing real-time onset detection and tempo estimation algorithms (such as Aubio, spectral flux analysis, or dynamic programming beat trackers) running on a live microphone buffer, coupled with precise AudioUnit scheduling to align clicks to predicted beat grids.
