Android/iOS: We've discussed plenty of times why it's important to exerciseyourbrain every day. If you're not sure where to start, Elevate can give you a boost by presenting you with different brain challenges every day.
The app will offer a rotating set of three games every day, each one targeted to specific brain functions like memory or math. You can pay to unlock more games if you're really into it, but you can keep practicing each of the three games as many times as you want each day until the set cycles out. It will also keep track of your progress each day so you can see how your scores match up, which can be helpful if you want to compare things like your performance in the morning to the afternoon on different days.
