Hey Product Hunt! Solo founder here. I started lifting at a 95 lb bench press. I logged every workout for years, and the whole time I still couldn't answer the only question that mattered: is this actually working? The scale can't tell muscle from fat. A workout log can't tell you whether your bulk is going to your chest or your gut. At one point I was literally tallying sets per muscle on paper, trying to figure out why my arms wouldn't grow. So I built Taper. It reads your weight, your waist, and your strength together and gives you a straight verdict: Lean Bulk, Clean Cut, or Losing Muscle. And it's deliberately honest. If your cut is eating your bench press, it tells you. Not being able to say "I'm progressing" is what makes quitting tempting, and vague apps make that worse. What's inside: A verdict that grades your bulk or cut from your own data Per-muscle progression on a live body map, so you can see which muscles are growing and which are stalling Fast, honest logging: supersets, rest timers, auto-progression, fair PR comparisons Progress photos side by side Widgets and Live Activities so your workout lives on the lock screen Local-first and private. No account required. Import from Strong or Hevy in one tap Every Pro feature is free for your first 30 days, no card required, and the core tracker stays free forever. I'd love honest feedback from lifters here: what would it take for you to trust an app's verdict on your own progress? And ask me anything about the build. I'll be around all day.
