By Steven Saccio Photography LLC · Health and fitnessWhy we expect it: Fog's clear concept, privacy-first design, and evidence-based Fog Score make its value easy to grasp quickly.
In short
Fog: Worry Tracker is a health-fitness app where you write a worry down, seal it, and get asked later whether it happened (Yes, Partially, or No). It suits people who want to test their anxieties against real outcomes. It stands out for its Fog Score, which tracks the share of worries that never came true, and it keeps everything on the phone with no account.
Summary by Debuts, based on the App Store listing.About
Fog is a worry tracker with one simple idea: write the worry down now, look at it again later, and see whether it actually happened.
Most worry apps ask you to work through your anxiety. Fog asks you to set it aside for a while — and then shows you the evidence.
HOW IT WORKS • Drop a worry. One line. Mark how heavy it feels if you want. • Choose when to look again — tomorrow, next week, next month. • Fog seals it away. You don't see it again until the day comes. • When it's time, Fog asks one question: Did this happen? Yes, Partially, or No.
YOUR FOG SCORE Every answer updates one number: the share of your worries that never happened. Over time it becomes your own record, built from your own life, of how often the worry was wrong.
QUIET BY DESIGN • No prompts, no streaks, no daily pressure. Open it when a worry shows up. • Reminders never show what you wrote — just "Time to revisit something." • Everything stays on your phone. No account, no servers, no tracking.
FOG PRO — one-time purchase, no subscription • Unlimited sealed worries (free holds 5 at a time) • Insights: your Fog Score by month, how often worries a day out vs. a month out come true, and whether the heavy ones are any more accurate than the light ones • Face ID lock • Export your archive as CSV
Available in English, Japanese and Korean.
Fog is a self-reflection tool, not medical treatment. If worry or anxiety is overwhelming, please talk to a qualified professional.
