**Reported bugs**

- Worked for checking broadband speeds which was the only thing in the apps you could use for free, which was fine but now it wants £1.99 or so a week just for checking speeds. Really you having a laugh deleted.
- Couldn't use the App.. it kept prompting me to enable the location permission in settings, which is already turned on. I turned the location off and back on thinking that would do the trick. Nope!
- Stopped working after one reading
