You can use Solomon on a mobile phone, but your experience will depend on how new your phone is. The newer the better. However, some parts of Solomon will not render on a mobile device. This has more to do with real estate. Solomon is best used on a Windows machine using a Chrome browser. The screen of a laptop is 6 times bigger than a mobile phone, there not all the graphics will render on your phone. While we think it is fine to use the phone as a quick look-up, we would advise against squinting at your phone for extended periods. It will not do your eyesight any good at all
