Powerlifting programming isn’t as complicated as spreadsheets make it look; once you strip away the noise, the structure fits comfortably on a phone. I think of it as two parts: plain sets/weight/reps/RPE/1RM, and the custom analytics you build on top. SigmaLifting handles the first part entirely on your phone with a mobile-first UI and a flexible data model that can express most spreadsheet-style programs. For the second part, you export the data and run it through your own tools (or an LLM) for whatever analysis you want.No one has commented on this post.
