Please remember that this is a logo for an app as well as a company...

Please make sure your designs are SQUARE SHAPED.

Also, make sure it can stand alone WITHOUT words too.

Also, I will not be accepting any designs that have a "gradient"

Gradients are not great for printing on multiple mediums

This "logo" design should also not embody anything to do with the words "personal best"

It needs to transcend the english language.

Hello,
sir please checked my design and feedback me, or any question and tips my design
thank you
