Stop checking five apps.
Your watch knows how you slept. Your log knows what you lifted. Your food app knows what you ate. Signl is the one place that puts it together and turns it into a plan.
Pick a goal
Strength, weight, body composition, sleep or a health marker. Signl builds a dated roadmap and tells you if you're ahead or behind.
It reads your body
Recovery, sleep, HRV and resting heart rate are compared to your own normal, not someone else's, every morning.
You get today's plan
The workout, the weights, the protein target and the bedtime that move your goal forward today. Nothing extra.
Built for people with lifting goals.
And everyone who wants their training, food and recovery to finally agree with each other.
A plan that adjusts to how you recovered.
Signl writes your week with sets, reps and suggested weights, then trims the day when your recovery is low so you keep progressing without burning out.
- Weekly plan with progressive overload built in
- Fast set logging on iPhone, Lock Screen and Apple Watch
- Personal records, sets per muscle and muscle recovery map
- 700+ exercises with how-to steps and pictures
