WHAT DOES THE  

“DATA CATCHING UP” 

MESSAGE MEAN?

The WHOOP app must remain open in the 
background of your phone to continuously 
transfer data.

Otherwise you will experience a delay as 
data is transferred from the strap to your 
app. 

Things to note:

WHOOP STRAP AND MOBILE APP

1. 

 

DO NOT FORCE-QUIT THE APP:

 The app cannot

run in the background transferring data once a 
user has force quit and data will not transfer until 
you relaunch the app.

2.

  

DO NOT USE LOW-POWER MODE:

 Make sure

low-power mode is toggled off in your phone’s 
settings. If it is toggled on, it will significantly 
reduce how often the WHOOP Strap syncs data 
with the phone.

3.  KEEP BACKGROUND APP REFRESH TURNED

ON:

 In your phone’s settings, ensure background 

app refresh is in the ‘on’ position since we require 
this to allow for background data transfers.

4.  AIRPLANE MODE MAY CAUSE DELAY:

 In

Airplane mode, Bluetooth may be toggled 
off on your phone, preventing the Strap from 
transferring data.

5.  STAY IN BLUETOOTH RANGE OF YOUR PHONE

TO ENSURE CONTINUAL DATA TRANSFER

The WHOOP Strap is able to hold up to 
three days of data, so if you experience a 
delay in syncing to your phone, your data 
will sync from oldest to newest once you 
are reconnected.
