When a worry is looping in your head, set it down here: what you're afraid of, and how likely it feels. Aftersky gently checks back in later and asks one simple thing: how did it actually turn out? Over time you build something quietly reassuring, proof from your own worries of how much of it simply faded. Research suggests that around 91% of the things we worry about never come to pass. Aftersky turns that from a statistic about strangers into a number about you. HOW IT WORKS • Set down a worry the moment it strikes, in the app or hands-free with Siri, a Shortcut, or the Action button. • Choose when to revisit it. Aftersky sends a calm reminder when the time comes, never a nag. • When the time comes, note what happened: did it arrive at all, and if it did, was it as bad as you feared? • Watch your Insights grow: how many worries faded, how often reality turned out gentler than the fear, and where your worries tend to cluster. CALM BY DESIGN • A quiet, uncluttered space with no streaks, no scores, and no pressure. • Reminders that bring a worry back only when you asked them to. • Insights meant to reassure, not to analyze. • Home Screen and Lock Screen widgets keep the reassurance close. PRIVATE BY DEFAULT • Everything stays on your device. No account, no cloud, no tracking, no ads. • An optional Face ID lock keeps your worries yours alone. • Export a backup whenever you like. It's a plain file you control. Aftersky is a self-reflection tool, not therapy, and it doesn't provide medical or mental-health advice. If worry is weighing heavily on you, please reach out to someone who can help. Aftersky includes links to support lines whenever you need them. Give your worries a place to rest. Then notice how few of them come true.
