Bad user interface Hi there  I tried to use your app on an S6 when I really need an app like this for a small home project but yours was hardly usable due to colors. You shoud make that buble white  or other color  so it should be contrasted with that blunt gray backgound. Because the buble has no evident color I eas strugling to see how acurate is its position. One star  because I couldn't use your app when I need it for the purpose it was built.
