You should post a clear photo, it may help to give some tips...

A lot of my Aloes get brown tips. Rest of plant is okay. Many things that can cause it, Too much water, not enough water, too hot, too cold. It's really not a big deal to me unless you have a serious problem with it. Pictures are best to use.

Looks to be an Aloe Vera plant. I don't have any but they are much weaker than a lot of the Aloes I have. Over all plant looks okay to me.

Thank You.

looks like over watering.

It looks fine aside from those marks. stop watering for a few weeks and you'll be able to tell if it's over.
