Parents need to know that Focus Dog: Study timer is a gamified productivity tool that rewards users for logging periods of focused attention. The idea is to start the timer then set aside your device while you focus on a particular offscreen, related task. The more time gets logged, the more donuts users collect to then "feed" their virtual dog named Focus. More donuts leads to leveling up which opens more options for collecting donuts. Focus Dog: Study timer wasn't designed specifically for kids. It makes the most sense for teens who have their own device and and feel it can be a distraction. A user account isn't necessary to play, though users who do create an account have access to more features. Registered users can invite friends to their network, or join an open live network, to compete with others for number of donuts they can earn. The free version offers is completely functional, though a premium paid version offers extras. Ads for the premium version are frequent and sometimes require users to click out of the ad screen to access the rest of the app. Users can also buy gems through in-app purchases. Gems can be used to level up in the game, or used to donate to a non-profit that provides help to dogs around the world.
