Stopped working-unable to get support

I gave it only two stars, and I’m being generous. I’ve used this app for years, never had a problem-but-it stopped working. I uninstalled and reinstalled it several times, but it just keeps crashing. I’m unable to get tech support. Is this app completely and permanently dead?

It seems that I’m not the only person who has had this problem. Someone should at least be available to help us!

Stopped working

This was a brilliant app I went to use it a few days ago and doesn’t seem to be working anymore my first thoughts was it could be the internet cutting off due to weather kept trying to open but it just closes down deleted the app n re installed it still not working I’ll download another app as it’s doing my head in now I used this a lot for converting cm to inches etc but Because it ain’t working now I’ll just go and download another app that is working so I’ve given u a one star as this isn’t the first time this has happened with this app n it won’t be the last maybe it needs updating but I can’t wait for that I need one that’s working all the time not just sometime

Stopped working too!

I have been using this app for many years as I am in the age bracket of pounds & ounces, feet & inches, and have found this app to be very useful over the years, then a few days ago it just stopped working, as ChrisStacey commentated in their review. It just keeps shutting down after you open it.
As Chris has said, would have normally given this app a 5 star rating and big thumbs up, but because of the inconvenience I only give it a 3.
Get the glitch sorted and I can put 5 stars back!
