Not all auto detecting BPM calculating tools are accurate. This is a manual tool (yes you have to tap yourself) to calculate BPMs. The tool can be tailored to your particular style including ignoring unusual tap frequencies and errors resulting from multi-touch. The algorithm used to calculate the final BPM is based off of my experience as a DJ of over 25+ years. This will be the only BPM tool you'll ever use. As with all my apps, this is free to use and is ads free!
