What it does
This app is a percentage-based workout helper with the ability to customize your percentages completely. It also guides you through your workout with handy barbell plating instructions and graphic. Most 1RM apps have built in percentage calculators that will increment by 5 percent. Many 1RM percentage-based workouts require specific percentages like "87%", or "102%". This app allows you to do just that.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
