Counts.pro hardware has been upgraded with a new firmware, version 1801.
For most users, this will be no problem, as many have already received the upgraded edition.
To tell whether your counts.pro hardware is compatible, look for the 1801 version in the bluetooth advertisement when connecting to the counts.pro device.
For other versions, contact firstname.lastname@example.org for advice. In some cases, an over-the-air update may be possible; for others, an equipment exchange may be required, free of charge.

The counts.pro app is live in the App Store!
