This works perfectly with the Node. So useful and I spent at least an hour going around my house finding the LRV value of random things, the dogs, my wall, my shirt, a mirror of all things, anything I could scan I did totally worth it. This is just an all around great app, I was vary impressed. I definitely recommend this awesome app.

The new version works wonderfully, great job on the app!

Great idea!

Love the LRV Guru app idea, but it is not connecting my iPhone to the Color Muse. I have the latest update and latest operating system upgrade. Is there a fix? Update: Thanks for your response! After fidgeting a bit, I was able to connect to the Color Muse. It's very helpful to be able to take LRV measurements on the spot. Highly recommend!

Developer Response ,

New version 1.3.2 released July 2017 fixed a bug that could cause the app to stall or not connect at all to the Color Muse. Apologies for any inconvenience! ~Lori

Very Powerful!

No crash issues since updates. This is the perfect app to calculate contrast between two colors using LRV numbers supplied by paint and materials manufacturers. I also use this app with my Color Muse from Variable to measure LRV. Getting color to do what you want just got a whole lot easier!
