About Trndi

Hi, I'm Björn. Since 2017, I've been building and maintaining Trndi (and it's predecessor TrayTrend), a free and open-source continuous glucose monitoring (CGM) tool for people living with diabetes. Every line of code, every bug fix, and every late-night support reply has been done on my own time, unpaid — because I believe nobody should have to choose between managing their health and paying for the software to do it.

Why your support matters

Soon-to-be ten years of development takes more than passion. Your donation helps cover:

• Test hardware
• Time to fix bugs
• Review contributions
• Keep up with OS updates
• Time to add new features!

I'm committed to keeping Trndi free and open source forever. If it has helped you or someone you love, or if you simply believe people with diabetes deserve open tools, any contribution directly keeps this project alive and improving.

Thank you for being part of this. 💙
