Welcome on board @Essamm, it's nice to see you here! Sometimes your Ionic can't detect you have taken it off, and it sees what it thinks is your pulse. Note that if you remove your tracker but it keeps moving, for example if you put it in a pocket or backpack, or it's near to a fan, the tracker may display an erroneous heart rate reading. And there are some factors that can affect the heart rate readings. Movement, temperature, humidity, stress level, physical body position, caffeine intake, and medication are some of the few things that can affect it. To prevent this, you can turn off heart rate tracking when the tracker is not in use.

Your tracker can have difficulty finding a signal, typically due to the tracker's fit. For example, wearing your band tightly may constrict blood flow in your wrist and affect the signal. We recommend experimenting with how high you place the tracker on your wrist. When you're not exercising, wearing the tracker just above the wrist bone--as you would a watch--typically works fine. However, moving the tracker up a couple inches can be helpful during high-intensity exercises or exercises that cause you to bend your wrist frequently. If you haven't already done so, please review our recommendations for wear and other tips shared by @SantiFitbit. 

Note that on Fitbit Ionic, the heart-rate value appears gray if your watch is searching for a stronger reading.
 

Occasionally your device may have difficulty getting a strong signal. If you don't see your heart rate on your device, first make sure you are wearing it correctly. After a short wait, you should see your correct heart rate again. On Ionic, make sure the Heart Rate setting is On. For additional troubleshooting, see Why don't I see my heart rate on my Fitbit device?
