Will ovulation strips fade??

Weird question, I am still pretty new to TTC and I have apps that I can take photos of the ovulation strips but I don’t know if it looks as clear. I was going to get a piece of paper and write the date and tape my ovulation test beside it each day so I can clearly compare them. Will the ovulation strips fade? has anyone done this or know if this is a good/terrible idea?

Thanks :)
