Some early versions of our Kinsa Smart Stick were released before newer generation smartphones.
As a result, they have limited compatibility and will need some troubleshooting.
Please check the lot number of your device. It appears as a 4 digit number starting with “1” on the back of the Stick (e.g. “LOT 1548”).
Then contact our support team at firstname.lastname@example.org and provide the lot number so that we can help!
