Feel calmer in 1 to 3 minutes, and get to know yourself. Pocket Stoa gives you guided breathing and short exercises for stressful moments, quick quizzes that show how your mind works, and an AI chat to talk things through. For heavy days and good days. Every calming exercise is free. HELP ON A HEAVY DAY (1โ€“3 MINUTES) Tap how today feels: good, okay or heavy. On a heavy day, pick what's weighing on you: worried, drained, stuck, on edge, low, or can't switch off. You get one short exercise for that feeling, with nothing to read first: slow breathing, sorting what you can control, shrinking a big task, or setting tomorrow's worries aside until morning. Every exercise is free, every time. BREATHING, ANY TIME Five guided breathing exercises: calm down fast, steady and focus, fall asleep, a longer calm, and cool down. Each says why it works. Breathe in one of six painted places. SLOW DOWN Nothing to read, nothing to get right. Paint a place with a tap, watch a slow window, or read one of 18 short picture stories. GOOD DAYS TOO Keep a good moment so it stays with you. Send good news to someone who'll be glad. KNOW YOURSELF Three quick everyday moments a day, like "After a party, you replay a chat with someone new." Pick what you'd do, and see the habit of mind behind it, like the spotlight effect. 54 patterns, each from published research. Your profile fills in as you go: your patterns, values, and what helps you. After about 5 days of answers, see which of 8 schools of thought you lean towards. A new dilemma on Today every day shows a little more. Your day's painting fills in as you go, and your good days light up a little painted world. QUICK GAMES Spot It: spot 5 thinking traps in 60 seconds. Would You?, This or That, Who Said It? (100 quotes), the Trolley (180 hard choices), a values auction, and 25 famous thought experiments. TALK IT THROUGH (AI CHAT) It listens, asks one question at a time, and ends with one line worth keeping. Or practise a hard conversation, or ask a great thinker. Replies come from an AI, Anthropic's Claude, and the app says so. It isn't a therapist. GO DEEPER: PHILOSOPHY 8 short courses, from the Stoics and Aristotle to Plato, Kant and the Buddha, 5 to 8 minutes a lesson. Plus the Meditations, the Enchiridion, 30 of Seneca's letters and 62 classic books. LITTLE THINGS A home-screen widget to check in with one tap. Soft sounds you can turn off. A weekly goal instead of a streak: miss a day and nothing resets. Milestones, and a look back at your month. FREE, AND PRO Free: every exercise, every time; 3 daily moments and their patterns; one "Why?" a day; your profile and your school; the games, with Spot It once a day; one AI talk a week; the first lesson of every course; two lives of The Last Day. Pro: every course, all the way; AI talks every day; every "Why?"; how you're changing, week by week; every Spot It deck; all 180 Trolley choices; all of The Last Day, a guided reflection on what matters to you. PRIVATE BY DESIGN Your check-ins and the moments you keep stay on your phone. After a help, you can tell us anonymously if it helped. No ads, no tracking across apps, and we don't sell your data. Start without an account. Sign in to back up and to talk, and delete your account in Settings at any time. FOR EVERYDAY STRESS Pocket Stoa isn't therapy or medical care, and not a substitute for professional help. "I'm not okay" is always one tap away, with support lines for your country. SUBSCRIPTION Pocket Stoa Pro is an auto-renewing subscription, monthly or yearly. The App Store shows the price in your currency, and any free trial, before you confirm. Payment is charged to your Apple ID at confirmation of purchase, or when a free trial ends. It renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel in your App Store account settings.
