Back in December when I had the flu, I took Sudafed one night to try to clear my nose so I could finally sleep. Unfortunately, I reacted badly to it (most likely because I took it after 2 days without food), and my heart raced all night, to the point that I almost woke my husband to take me to the ER.
I tried several times to take my pulse myself, but I was slightly delirious, and I just couldn’t get a good count. A few days later, my sister-in-law used the classic line, “There’s an app for that!”
Sure enough…there is!
Instant Heart Rate uses your phone’s camera to detect the pulse from your fingertip – by tracking the changes of the color of your fingertip. Pretty crazy, right?
To take your pulse, you simply place the tip of your index finger on the phone’s camera. It begins to track your pulse, beeping and recording every heartbeat on a chart. You can also save your heart rate measurements and tag them with things like #morning, #postworkout, etc. to see patterns.
It took me a few tries to figure out the best way to hold my finger, but now I can get a pulse within seconds. It’s pretty addicting to see how it varies at different times of the day and while I’m working out!
