From a thematic point of view, incorporating a mobile phone as part of the logo (or something evocative of a phone/phone screen) and that the product (a liquid that is applied to the front of the phone screen) acts as armor or a shield for the glass of the phone screen.
You can use this font or something compatible with it.
The logo should make sense/be appealing to all ages as the product is directed to consumers of all ages (well, at least between 7 and 70).
Do not include gradients as it will be printed on physical media (too many colors will be a problem). The main geography of interest is the United States.
