I have been looking for an app for my android. I have almost all of the markers I want (several years of collecting them), but every once in a while, I still find myself thinking "wait, did I want this one?? Do I have it??" LOL
I have more than one of several markers!!! UGH, I hate that!!! I get all excited that I got 10 new markers, only to find out I had one already!!! This will get rid of my wrinked worn out chart!!!
So have I! I bought them at a Craft Fair and the light was really weird - kind of bluey. It wasn't till I got them home that I realised I had duplicates. That's when I started keeping a note of what I had.
I used Notes on my iPhone originally, but the note kept disappearing when I got my new iPhone so I lost confidence. I've been putting the colours and numbers on little charts in with the pens, and just photographing the charts with my iPhone. That worked better.
