Stop guessing. Start lifting.
SpotterAI builds your workout, picks your weights, and adapts when life gets messy. The only fitness app that does the thinking for you.
Most fitness apps are just empty spreadsheets
They hand you a blank screen and say "log your sets." That's like giving someone with writer's block an empty page. If you already knew what to do, you wouldn't need an app.
"Do I do chest today? Or legs?"
"How much weight should I put on?"
"I missed a week. Is my plan ruined?"
This is what it feels like.
You walk into the gym. You open the app. Everything is ready.
