Odozi (like odyssey, get it?) is a roughly two-minute-a-day journal for your mental wellbeing. This was built because I personally wasn't great at finding the time to journal in the way that I want to journal. Mainly, the app is focused on mood, sleep, gratitude, a daily win, a source of tension, a free journal, and a couple other data points. This entry should be low-friction even on the busiest of days. In the background, Odozi will capture context from your day (your neighborhood, steps, walking distance, sleep, and screen time) so each entry is already half-filled by the time you open the app. Over time, Odozi turns those small daily check-ins into something you can actually look at: * Mood trend charts that show how you've been feeling across weeks and months * A map with color-coded pins so you can see where your best - and worst - days happened * An analytics view so you can spot unseen correlations between any two data points * A Spotify-Wrapped-style Year in Review you can share * A word cloud built from your own journal entries The app is private by design. There are no accounts and no third party tracking. It will remain that way. Your entries live on your device and nowhere else. Location, HealthKit, and Screen Time access are all optional - the journal works without any of them. Furthermore, if you do want syncing across devices, you can enable iCloud sync in the Profile tab. This will sync your journal across your iPhone, Apple Watch, and Mac using Apple's secure CloudKit service.

Turn your daily steps into a journey across Japan and East Asia. Postmarks transforms ordinary movement into a slow, meaningful adventure. Walk in real life while traveling between real cities, collecting vintage stamps, finding souvenirs, earning achievements, and filling a passport that grows with every step. This is not another pedometer. It is a reason to go outside. ◆ YOUR WALK HAS A DESTINATION Every step moves you along routes inspired by real places—from Tokyo and Kyoto to snowy northern roads, Korea, Taiwan, Hong Kong, Macau, and historic routes across China. ◆ EXPLORE JAPAN AND EAST ASIA Begin with Heart of Honshu, a complete journey included free. Expand across Japan, South Korea, Taiwan, Hong Kong, Macau, and China. Choose your pace, discover secret detours, and revisit completed routes. ◆ COLLECT VINTAGE STAMPS Reach a city and unlock a handcrafted vintage stamp. • Common, Rare, Epic, and Legendary stamps • Hidden secret-stop stamps • Separate Day and After Dark collections • Stories revealing the real places behind the artwork Every stamp marks movement you actually made. ◆ FIND SOUVENIRS Trail Finds turn walks into small discoveries. Pick up keepsakes from stalls, festivals, markets, shrines, parks, and stranger corners of the journey. Keep them in your Backpack and revisit each find’s story. Some are common, some rare, and some appear only After Dark. ◆ UNLOCK ACHIEVEMENTS Earn badges for steps, streaks, routes, destinations, secret stops, souvenirs, and special combinations. Display them in your Badge Case—some goals stay hidden until discovered. ◆ MEET YOUR TRAVELER CARD Your Traveler Card brings together your route, walking tier, stamps, achievements, and favorite keepsakes. Make it yours with collectible banners, frames, and seals. ◆ WALK WITH FRIENDS Connect privately using invite codes, exchange Traveler Cards, follow each other’s progress, and spot friends’ seals across the map. Postmarks shares coarse virtual-route progress—not your live location or raw health data. You control whether friends see your weekly steps and recent activity. ◆ EXPLORE EVERY CITY Reached cities include curated guides to local food, landmarks, culture, history, and surprising details. Artwork stories connect each stamp to the place that inspired it. ◆ WALK BY DAY OR AFTER DARK After Dark transforms familiar routes with a moonlit map, its own stamps, and night-only discoveries. Switch modes on unlocked routes without returning to the first city. ◆ A JOURNAL THAT WRITES ITSELF Postmarks creates travel-journal entries with your steps, streak, route progress, reached cities, and memorable moments. Read your history—or replay your journey day by day on the map. ◆ BUILD A HABIT NATURALLY A city ahead, a stamp to earn, a souvenir to find, or a streak to protect makes every outing part of something bigger. Forgot to log yesterday? Everyone gets one-day retroactive logging, helping you keep your journey honest without losing momentum. ◆ KINTSUGI TOKENS Mend one missed streak day from the last week. Your step totals stay honest; only the streak continues. Every traveler starts with one free token. ◆ PROTECT YOUR PROGRESS Secure your journey with Google or Apple sign-in. Your routes and collections stay connected to your account and can be recovered on another device. ◆ FREE TO START Heart of Honshu includes a full route across Japan with cities, stamps, secret stops, journaling, Trail Finds, achievements, and the core experience. Optional one-time purchases unlock more routes across Japan and East Asia, additional collectibles, expanded pace options, and Day / After Dark access. No subscription required.
