Millimeter Pro - screen ruler users say on Google Play
Very very well put together. Minimalist and extremely user friendly. There's nothing I would change or add. Completely free of ads and privacy intrusions. This app should be part of every phone's toolset and I sincerely hope the developers keep the excellence flowing.
This app seems to be extremely accurate, but I do find it a little confusing to set up & use. I'm sure it will become easier as I use it more. The area function looks to be especially useful. Thanks. I consider it money very well spent.
Honestly I bought it looking for a AR ruler. I didn't know what to call it until I saw more apps after I found it was unsufficient. I didn't know a "real life ruler" became a ruler. I thought it was a ruler replacement for real life. Honestly. After thinking about it, it might be handy to have a real world ruler as a secondary tool. Not handy as a mini-golf tournament runner. I need distances significantly over 10 cemtimeters.
It kept asking me to place on level surface
Wanted an app to measure everyday objects like furniture or shelves when out and about. This app will only measure items that literally fit on your sceeen. This may be fine if you only need to measure dolls house fittings but not too many uses otherwise. If you are a borrower then this the thing for you, but, if you are a tiny person relatively speaking carting around a mobile to measure your home its not at all practical. For normal size people a bit of a waste of £1.39.
