Good news! My 3D mapping and find-logging app (CoilTrail) is now unlocked globally 🚀
Hey r/mudlarking! 👋
A user in my previous thread suggested I make a new post to update everyone, so here it is!
A while ago, I shared a project I've been working on—an Android app called CoilTrail, designed to help track routes, log finds, and use 3D LiDAR/hillshade maps to spot old riverbeds and structures.
At the time, it was limited to just a few countries. But after a lot of coding behind the scenes, I’m super excited to announce that CoilTrail is now officially unlocked GLOBALLY! 🌍🔓
What this means for you:
-Global 3D Hillshade & Satellite Maps: A new slider lets you adjust the 3D terrain opacity anywhere in the world to spot interesting geographical features. (Note: I am currently working hard on integrating ultra-high-res local government topographical data for individual countries, but this global 3D base layer is live and works perfectly everywhere right now!).
-100% Private & No Login Required: All your routes and finds are saved locally on your phone's memory. You don't need to create an account, and your secret spots stay strictly yours.
-Log Your Finds: Pinpoint exactly where you found an item on the riverbank, add photos, depth, and target IDs.
Track Your Routes: Never lose a good spot or forget which part of the foreshore you've already covered.
A quick note on pricing for full transparency: The core features of the app (like standard maps, logging your finds, tracking routes, and local storage) are completely free. The special high-res/premium map layers are part of a Pro subscription. As an independent solo developer, this subscription helps me cover API/server costs and funds the future development of the app so I can keep adding more cool features and specialized maps for the community. I hope you guys understand! (There's also a 7-day free trial so you can test it out first!)
The update is live right now on Google Play. I'm building this for you guys, so if you take it out on your next mudlarking trip, I would absolutely love to hear your feedback!
Happy hunting! ⛏️
