Foci is the deep work tool for the 21st century. Distractions are prevalent on your phone and it's time that you become focused. This is a productivity timer which tracks how long you can stay off your phone. This will allow you to be present in the moment.
@marvinpoo You're completely right! There are a lot of focus timers. However, I have used a lot of them on iOS and none of them seemed like tools. They all seemed like quick gimmicks to get money (ads, payments, etc.). This one is primarily a tool, nothing else.
