Geoff would come downstairs to find his eighth grader scrolling social media, enjoying her summer freedom. Around the same time, he asked his sister-in-law, Peyton McDavitt, when his daughter should start preparing for the SAT.

After 20 years in SAT prep, Peyton’s advice was simple: the one thing she can start doing right now is building vocabulary through reading comprehension a few words at a time.

That sparked the idea. What if the apps stayed locked until the day’s words were done? A few minutes of learning before the scrolling, building vocabulary and sharpening reading comprehension long before the pressure of test season.

SATShield brings that idea together with Peyton’s SAT prep experience and the team at Sharp Notions.

We built this for our family. We want to share it with yours.
