Frequently Asked Questions

We've answered some of the most commonly asked questions about Tether.

We made Tether

We're FiaFo, a UK based digital innovation studio. While we were working R&D for our Bluetooth Smart projects, we uncovered this cool feature and started trialling it amongst ourselves at home and in the office. We had some spare time just before Xmas 2014 and decided to make our internal tool available for others to use.

Now that Tether is production ready, we've plans to explore bigger ideas. So stay tuned for additional features to be added this year (2015). In the meantime, please let us know how you get on using Tether ~ the wireless leash to your Mac.
