Antenna Aligner is a utility tool developed by Chris George that helps users align and tune their Freeview aerial in the UK and Ireland. This app takes the guesswork out of aerial alignment and fine-tuning. With just a single click, Antenna Aligner shows users where to point their aerial and which channels to focus on. The app provides a list of transmitters to select, and these are chosen based on their calculated signal strength at the user's current location. It's a simple process that doesn't require an internet connection.

However, users of iPod Touch should note that the compass view in the app will not work as these devices do not have the compass hardware. Nonetheless, the list of transmitters with the bearing will still work. Additionally, WIFI-only iPad devices may not have GPS, and in such cases, the location can be specified using postcode. Magnetic covers can affect the compass hardware, so users are advised to remove the case if they experience problems with the compass.
