Great idea but has bugs

I was amazed by the idea. It is so simple but yet so useful. Can't believe I haven't thought of it before. The interface is well thought out and functional.
Until I clicked on the settings button, it actually froze. Also when I tried to switch to another app, it kept freezing and kept switching back to this app which was already frozen. Please fix the bugs. It is truly a great app. Good job

Developer Response ,

Thank you! I will release a bug fix soon :)

I am amazed with the apps concept but I am having some issues with my iphone X,
1) when i try to measure something it doesn’t give me accurate measuremnts what i got by a measuring tap!
2) After using 2/3 minutes it freezes my phone!
3) When i close this apps it freezes my phone for almost 30 seconds!
It’s still happening after your latest update last day!
