How to find spot remove tool? I am using lightroom 5.1

Rob's correct if you are using the cloud based Lightroom.

And Jao's right, there is a big difference between the applications and the naming hasn't helped, especially in regards to searching for tutorials on YouTube for instance.

(I believe it isn't so much of a port from Lr Mobile on the phone, but was developed initially from Adobe Carousel/Revel which crossed all platforms).

Also, there are two versions of Lightroom. Lightroom Classic is what most of the tutorials are for. Lightroom 5.1 is a port of the mobile operating systems (i.e. iOS and android) to dektop operating systems and stores all your images in the cloud. CLassic stores all the images on your local computer. It is a different program. To add to the confusion, the CC moniker was used for both the predecessor of Classic and for the predecessor of the cloud program. Make sure you have what fits your work style best as they are completely different beasts.

The Spot Healing Brush is now a 'Bandaid' icon- Get it? "Healing" "Spot"!

Is this not what you see?
