About Invertium
Hi, I'm Invertium — I build free apps and tools, mostly for makers and DIY electronics folks. My apps have no ads, no accounts, and no tracking; coffee is the only thing that funds them.
If something I made saved you time — like BMS Dash, my Android dashboard for JBD / Xiaoxiang smart battery packs — a coffee says thanks and helps pay for test hardware and time to build new features.
