Odyssey builds daily scratch maps of where you've been using your iPhone's location, and lets you check-in to places with additional details. Everything is private and stored on your iPhone. Remember where you've been, without anybody up in your business.
I'm really excited to share with you something I've wanted to build for a long long time.
Your iPhone knows exactly where you are, all the time. But most location and mapping apps use that to track you, sell your data, or push social sharing. They’re built for discovery and navigation, not memory, and adding your own context (like your photos, or ratings and notes about a place) often means broadcasting it.
I built Odyssey to do the opposite.
It’s focused, automatic, and private; built to help you remember where you’ve been, not share it.
How it works
🗺️ Logs your location in the background and builds daily maps.
📍 Lets you check-in with people, notes, ratings, photos.
🔍 Search just your check-ins and history.
🫥 No social features. No accidental sharing.
🔒 Private by design. Everything stays on your iPhone.

Hey Daniel! Really love what you’ve built with Odyssey — making apps more personal is a big deal for user experience and retention. 🔥
I help SaaS founders improve onboarding and engagement using strategic copy and emails. If you're ever looking to optimize that side of the user journey, happy to share a few insights (no strings).
Congrats on the launch 🚀 — wishing you big wins ahead!
Love the idea of a private, memory-focused app that helps you track where you’ve been without the social sharing pressure. Will there be an option to export or back up your check-ins, in case you want to keep a personal archive or share selectively in the future?
Partially, it reminds me https://humbo.com/ Would like to pair it so that each time I visit any country, it would send a signal to Humbo and "colour" the country on the globe.

Who hunted Odyssey?
Odyssey was hunted by Daniel Yoo. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
