Make your problems feel small. Spared gives you instant perspective by showing your brain what real hardship actually looks like. Your brain makes your problems feel huge because it has nothing to compare them to. We fix that. The app's audio sessions cover real hardships that real people endured - the type of hardships that were common for basically all of history. You enter a problem, get matched with a session, listen to it, and return to your life with your problems feeling a whole lot smaller. HOW IT WORKS Enter your problem. Get instant perspective. Listen to the full audio session. Each session is a short, narrated story drawn from real history. A stone hauler at Giza in 2560 BC. A cholera victim in 1849 London. A fur trapper wintering alone in 1812. You hear the details of their day. You feel the weight of their reality. Then the session ends, and you are back in yours with one thought: how incredible it is that you never have to live that life. WHAT IS INSIDE Instant reality check: type what's stressing you and get historical perspective Audio sessions across five categories: Work, Money, Stability, Safety, and Health Narrated audio with synchronized transcripts AI-powered chat for session recommendations and guided reflection Track your streak and rise through 7 levels THE SCIENCE Harvard researchers call it prevalence-induced concept change: your brain expands your problems to fill all available space. Spared gives your brain a bigger frame of reference so your problems shrink back to their actual size. One session is all it takes to put your problems back in perspective. Over time, it's one of the best ways to reduce stress, build gratitude, and feel happier. Payment is charged to your Apple ID account. Subscriptions automatically renew unless canceled.

That afternoon espresso might still be affecting you at midnight. Caffeine has a half-life of about 5 hours, but most people never think about what that means for their body. Mr. Caffeine does the math for you. Log your coffee, tea, or energy drink with a single tap. Mr. Caffeine calculates how much caffeine is still in your system in real time and shows you how it affects your energy, focus, and sleep. HOW IT WORKS Caffeine doesn’t disappear after your last sip. It stays in your system and fades over time. Mr. Caffeine tracks this process using a caffeine half-life model, showing you a clear decay curve throughout the day. You’ll always know where you stand and whether that next cup is worth it.
