Was good at one point…

I first downloaded this app years ago and I used it almost daily. It was great back then when it was working. Recently, after the latest Apple iOS updates, the app is broken and it will not open. I get a brief flash of the app graphic as it attempts to start and then it crashes. I tried uninstalling and reinstalling the app but did not fix the issue. If you are using the latest Apple iOS beware; the app will not work.

This App no longer works

It keeps crashing when I open it. So far it has not worked and the last update is over 3 years ago! I am using iOS 15.6 and if this app hasn’t been updated in 3 years it won’t work for anyone with at least iOS 13 or higher.
Stay away until the developer updates it to work with iOS 15 or higher.
I now use Unit Convertor as it still works the way it is supposed to.
Apple why don’t you make a standard app for converting units? It could even be incorporated into the calculator app.

Doesn’t work any longer

I used to use this app quite a bit but it won’t launch any longer. It hasn’t worked in ages. The splash screen shows and the app just goes away. It still shows as running if you double click the home button but it won’t work. I could understand it for a short while but it’s been going on for too long. The app seems abandoned.

Please help!

I’ve used this app for years and really depend on it for convenience. It was fast, easy and intuitive. I don’t need a complex app with fancy features.
After the last few Apple updates it will not come up.

Please fix it! Thank you

Suddenly crashing

I’ve been using this app for years and it’s been good. Tried using it today and all of the sudden it just crashes. I tried deleting and reloading but it crashed again.

IOS 14.4 issues

I have been using this app for ages and I enjoy its simplicity and accuracy. But since I’ve upgraded to iPhone 12, the app seems corrupted and is not able to even open. I have tried to delete and reinstall it several times without success. I hope the issue will be fixed soon.

Good if it worked

I’ve used this app on and off for several years but in the last years the app crashes and won’t even open.
I have deleted and reinstalled it twice and the same issue remains!!
I don’t know if the developers have abandoned the app to keep up with os changes but he last update was a year ago.
Too bad, it worked pretty well back when it actually worked!!!

App Issues

I have used this app for years and love it, but over the past year, it no longer opens. I thought it might have been because I had to old a phone, but even after a phone update, it still won’t open. Please fix the issue.

No longer remember the last time this app worked

I encounter the same issue many others describe here - the app launches with a splash or start-up screen and then sends one back to the device home screen. Trying to toggle to it in the list of background apps runs into the same problem. It was my go-to app for conversions for years, possibly close to a decade, and I remember it kept on improving with more conversion options, but very unfortunately I no longer recall the last time I was able to use the app stably.

Not working at all today

I’ve had this app on all of my apple devices since my Iphone 3. It has worked flawlessly until today. I tried several times to get it to work today on my iphone 11. It worked fine until today. It won’t even turn on. The intro panel comes on and stays on for about 5-8 seconds and then nothing. It shuts down and goes silent. What gives?

App crashes

I loved this app very much and I used it almost daily for my job but since about three weeks every time I open the app it crashes right away and I don’t know why. I deleted and re- installed the app and I have the same issues. Could you have an update ready to fix this app from crashing on a 12 Max phone.

Thx

Won’t open for iPhone 11Pro

This has been a great “go-to” app for easy/convenient reference for several years now - ever since my iPhone4... However, now it keeps crashing when I attempt
to open it... - can’t even stay open past the load-screen on my iPhone 11Pro. (Couldn’t access App Help for tech support either - came up as blank page...) Help please!

if they can get it updated to stay open and operational again, I’d be very happy to keep using it!!

Not working

I had this app for a while and it was good but lately when I open it i closes a second later so I can’t use it. I thought at first it was because it was on currency when I used it last and I didn’t have signal (working offshore) but now I’m home and it’s still doing it. I have deleted this app and will look for another one to take it’s place.

Love love love this app

Download this app and stop searching on google to convert pickles into airplanes because this app will do it for you. Seriously, this app has been around for a long time now and it is still the best unit conversion app out there. Highly recommended!!

No longer a 5 star app

For the past several years, this has been the “go-to” app for units conversion. Now, after the last iOS update, this app no longer opens. You get the familiar splash screen, and then, poof! Gone. The app has not been updated in a year (first problem), and the developers web sit can no longer be reached (second problem). So, with no way to report an issue, no recent activity or updates, this app has rendered itself useless.
Time to search for a replacement.

Needs a patch or something

I have loved this app for years, and I use it all the time, unfortunately the last iOS update has rendered it unusable. It won’t even open, when I try it goes to the loading screen and then right back to the blow up on the folder I have the app icon in on my Home Screen. So to the developers please do something ASAP so I can use this app again!

I won’t open on my phone any more

I love this , it’s super convenient but it stopped working on my phone for some reason. No matter how many times it delete and reload, it doesn’t help so I’ve been forced to find another one to use. Please help

Worked great but...

The app was working great but it’s not even opening up anymore. I had it on my iPhone 11 Pro Max with the latest iOS version and it didn’t open. Updated to iOS 14 and same thing. Deleted app and reinstalled and same thing. If this gets fixed I will reinstall app. Until then I will have to use something else

Not working on my iPhone SE

Have used this ap for so many situations and has always been great; however, I had to upgrade to an iPhone se and the ap won’t even open, much less work. I’m left hanging because there is no ap that compares.

Good but not great

There are many conversations missing, example would be oz/in2 to other pressure units.
Another example is barrel (oil) to gal us, why is in app is barrel (fluid) to gal us, which is not the same.
Engineers need to use many not on this app.
Women’s shoe sizes are of no interest, why have these and not ones needed for engineering design?
There is a Custom selection that used to work where these missing conversions could be entered, but it doesn’t work anymore, it kicks you out of the app if you chose it.
This app is ok but could be much better.
