What's New in Plynx
1.3.1
September 7, 2026
Meet Archimedes, the assistant. Ask it why your board reboots, what a dashboard does, or for a sketch: it reads your boards, dashboards and saved sketches, checks a wiring before you build it, and writes or edits code for you. Every change lands on a card you confirm. Free, with a daily limit. Sign in with Apple, next to the email login. Switching between accounts now works with Apple accounts too. Home Screen widgets: add as many as you like, each with its own board and pin. The Overview widget lets you choose which values it shows. Fixes: the LCD widget kept losing its pin when the app was reopened; moved widgets could jump back after closing the project settings; a few edit-mode gestures and text sizes behave better.
