Looking to work on your health? You don’t need a smartwatch to measure your heart rate. 

• Cardiio: Heart Rate Monitor is an iPhone app that uses your phone’s camera to take a reading of your pulse. Place your index finger on the back camera, and the app will measure your heart rate by detecting color changes. Hold your phone steady and keep still. It works with iPads, too.
• For Android, Heart Rate Monitor works similarly. Cover the back camera, stay still, and you’ll get a reading.

Just remember, apps like this are not a replacement for seeing a medical professional or talking to your doctor if you’re not feeling well.
