Semper puts a puzzle on the lock screen, using the art and science of implicit learning to enhance language, vocabulary and math skills unobtrusively every time you unlock your phone. On average, we unlock our smartphones 40 times a day. Each time we do, we have an opportunity to train our brains. Unlocking the phone with a puzzle takes a couple of seconds, it is always optimized for you and happens again and again – without being annoying. It just works.
