The Hrate – Heart Rate Zones Calculator uses your resting and maximum heart rates to generate a series of zones. The body responds distinctively while the heart rate is within each zone. Use Hrate to target a specific heart rate and help you reach your training goals.

Also available bundled in the Hcalc app.
