4. Pairing your Device

Make sure Bluetooth is 

ON

 in your smart phone, and 

open the Runmifit app on your smart phone. For pairing, 

please make sure to place the tracker near your phone, 

find the “Add Device” in the app. Then it will enter the 

Bluetooth searching page to find the device, tap the 

pairing name S90, and select Pair. To avoid signal 

interference, remove all other Bluetooth devices near the 

fitness tracker when pairing.
When pairing for the first time, please open the app, 

register your email address and accept the user 

agreement. You will receive a verification code by email, 

enter this code in the app and login. 
Complete your personal details in the app to calibrate the 

device – your gender, age, weight, height. 
After successful pairing, the app will automatically save 

the Bluetooth address, and when the app is open or 

running in the background, it will automatically search 

and automatically connect to the device. Data 

synchronization will occur automatically from time to 

time. You can also manually pull down the data to 

synchronize data on the app homepage. 
The FLASH activity tracker saves 7 days of offline data. 

Please ensure that the app is opened so that 

synchronization of data can occur, and historical data can 

be viewed in the app. 
Please do NOT directly search for the device in the 

Bluetooth list in your phone settings, when pairing. You need 

to enter the app to search for the connection and pair.
To choose metric or imperial measurements, go to the 

app, go to your profile, Me, go to System setup and select 

your choice.
