Spotter builds you an adaptive program for whatever you're after — build strength, build muscle, general fitness, lose fat, or build endurance — with whatever you've got: full gym, dumbbells, or just your bodyweight and cardio. Then it adjusts every session from how you actually trained. Live and free, right now.
Free account, no card. Adaptive programming + logging across weights, bodyweight, and cardio — walking, running, cycling.
What you get
Most apps either hand you a generic plan and disappear, or charge $200/mo for a human coach. Spotter gives you a program that calibrates to your real performance every session — free — and connects you with a real coach the day you want one.
Build strength, build muscle, get generally fit, lose fat, or build endurance — with a full gym, just dumbbells, or nothing but your bodyweight and cardio. Spotter builds the plan around what you actually have.

VitalCoach handoffWhy this matters
Most fitness apps treat your phone like a digital clipboard — they log what you did and stop there. Spotter reads it and decides what's next.
Log how the set actually felt and Spotter recalibrates the next one: ease off when you came in short, push when you've got more. Switch to dumbbells, bodyweight, or a cardio day and it reworks the plan to fit — no spreadsheet surgery on your end.
No more training alone wondering whether today counted.
