ATLAS provides users with short, easily digestible summaries of what the laws of each state say on supported topics as well as the full text of the relevant laws. You can view the data on any covered law for any state at any time or be automatically updated with the laws effective in your current state.ATLAS does not require a data connection for you to receive updates on changes due to crossing borders. Assuming you have a GPS signal ATLAS even works in airplane mode!
This app covers over 40 law subjects in six categories. Those categories are traffic, law enforcement, alcohol, taxes, guns and marijuana. Since It's unlikely you'll care about all the categories or individual laws, you can set your priorities for each and only be informed about those that matter to you.
