Pick a song or loop on your device to estimate its tempo. The file is decoded in your browser and never uploaded.An estimate from the first 2 minutes. Clear drum beats work best; songs often read at half or double the tempo you feel, so check by tapping.
Tempo names use the ranges in the Wikipedia article “Tempo” (very rough, for 4/4).
