## What is Cytronex App?

An essential tool for owners of Cytronex electric assistance kits manufactured from May 2021 onwards.
 
Using this app you can:
- Monitor your Cytronex bottle charge level
- Adjust the assistance power for each of the assistance levels
- Adjust the brightness of display LEDs
- Select between hub and derailleur gears for your bicycle
- View the Cytronex user manual and fitting instructions
- Send logs containing diagnostic information to the Cytronex support team
- Access an online troubleshooter to assist with common issues
- Upgrade the firmware in your Cytronex bottle
 
Note that this app connects to a Cytronex bottle via Bluetooth, so you will need to enable Bluetooth on your device to use it. Most of the functionality of the app is only available when connected to a Cytronex bottle (built from May 2021 onwards).
