Hi, I'm Levi. Every workout used to start the same way: opening Google Sheets on my phone, scrolling to find the right spreadsheet, then switching to my calculator to figure out what goes on the bar. I'd logged every lift in those sheets since June 2025, so I turned them into an app that does the math for me and shows its reasoning for every lift. What it does: logs workouts, shows a calendar and history, and plans the next session. What I decided not to build: a social feed, exercise videos, or an Apple Watch app. It is a PWA, so there is nothing to install from a store. The free tier is the notebook and it stays free. The paid part is the planning. If you stop paying, you keep your log and can export it. I would like to hear which part of the planning you disagree with, because the rule is simple and I would rather fix it than defend it.
