Slouching progresses before you even notice it. And by the time you do, it might already be too late. “Posture Patrol” is a simple app that watches over your posture with notifications. There’s only one thing to do. When a notification arrives, straighten your back. That’s it. And little by little, your posture will improve. ■ Patrol Cats Protect Your Spine Your spine is always at risk. To protect your posture from collapsing the moment you let your guard down, the “Patrol Cats” make regular rounds. Sometimes they stake out, sometimes they patrol outside, and sometimes they even guard other people’s spines. A world where every spine stands tall — that is the “peace of posture” this app aims for. ■ Simple, So You Can Keep Going • Get notified • Open the app • Fix your posture That’s all. No complicated actions or difficult settings. Because it’s simple, you can keep going. And because you keep going, you improve. ■ A Few “Pointless” Features This app also includes a little bit of fun. • Release cats arrested for bad posture • Send them to posture rehab • Rank up your patrol (aim for Legend) • Unlock more meow notification sounds It may be pointless, but it’s fun. ■ Recommended For • People who work at a desk • People who tend to slouch • People with shoulder or neck tension • People who struggle to build habits ■ Start with Awareness Improving your posture doesn’t require anything special. Simply noticing it, again and again, will gradually change your body. This app helps you take that first step.
