About the developer
Hi — I'm the solo developer behind Trajion. I started this project because I needed a journal that respected how traders actually work.
I've been trading and writing software for years, and I kept running into the same problem: no journaling tool felt like it was built for someone who takes both disciplines seriously.
Spreadsheets were flexible but messy. Generic note apps lacked structure. Existing trading journals were either too simplistic or overloaded with features I'd never use.
So I built Trajion — a platform that makes logging fast, reviewing painless, and analytics honest. It's the tool I wish I had when I started, and I refine it every week based on real usage.
If you have feedback, feature ideas, or just want to talk trading and tech, I'd love to hear from you.
Trajion is free to use, but if it's made a difference in your trading, a small donation goes a long way toward keeping the lights on and the features coming.
Trajion is free forever, but building and maintaining it takes real time and resources. If the app helps your trading, consider a voluntary donation to keep development going.
Donations are completely optional and never required to use Trajion. Every feature stays free regardless. Learn more about supporting us
