You can track your times in the iOS app with Siri.
To do so, activate the corresponding option in the settings of the timr app.
You can do this in the "... More" tab.
Choose now which Siri commands you want to use, e.g. "Start Working Time".
In the next step you can add the command to Siri and choose which action should be performed.
Once you have added your desired Siri commands, you can simply control your time tracking with "Hey Siri!
NOTE: If the option to use Siri commands is not available in the timr app, either your timr app version and/or your iOS version is not up-to-date enough.
