How it works

A day with Coach.

Follow one member through one day on the Polaris app: the morning brief, lunch logged in one line, where the day stands on Today, and an evening workout logged set by set in Training.

A day with Coach: one day with Sam, a fictional member. Morning: Sam steps on the scale, then taps the morning push. Coach reads the weigh-in, the night and recovery, and makes one plan for today: 206.1 lb, 206.4 on the 7-day average, 7 hours 25 minutes of sleep and a sleep score of 82, recovery green, so the upper-body session runs as planned. Lunch: Sam types @Chicken breast @Jasmine rice with 6 oz chicken, 1 cup rice; Coach puts the numbers on a card, and nothing saves until Log it. Afternoon: Today shows where the day stands, and what's still open: weight, steps and the Daily score. Evening: the workout starts right from Today, with last time's numbers already there. Sam checks each set as they go, taps Finish, and Coach sees every set. It all lands in History, and Coach plans the next session from it. Anything else? Just ask Coach. Polaris. Find your North Star. Stay the course. Request Alpha access at polarishealth.ai.

Jason · Polaris co-founder

Why I built Training.

Jason used to hate the gym. He paid for an app to keep him accountable, stopped anyway, and spent most of 2025 hurt. Since May he has logged 44 strength workouts and lost about 16 pounds, and Polaris sees every set. Watch his real numbers in 90 seconds.

Why I built Training. Jason, Polaris co-founder. I used to hate the gym. In 2024 I paid for an app to keep me accountable. By summer 2025 I'd stopped: cardio, or nothing. One injury after another, and foot surgery at the end of 2025. So I built the accountability into Polaris. Since May: 44 strength workouts in 23 weeks. On a cut since May: 212.7 to 198.7 lb, 14 lb in five months; body fat 20.2% to 18.8% on a smart scale. Sunday, 8:30 AM: every morning Coach sets the target; Sunday, goblet squat, 30 lb × 12. 11:22 AM: every set lives in Training, and last week's numbers are right there. 12:05 PM: the plank timer counts me in, holds the time, and checks the set. 12:07 PM: finish, and Coach sees it: Workout saved, 2 PRs, 45 minutes, 5,940 lb, 25 sets. 12:19 PM: no more logging workouts in chat; Coach already has them. This week: history, records and volume, week by week. 3.7 lb to go: at 195, Coach asks what's next. For me: building muscle. Strength matters more every year, for men and women. Start where you are. Polaris. Find your North Star. Stay the course.

Everything here works in the Polaris iPhone app today. Sam is fictional, and so are his numbers. Jason's are real.

Is Alpha really free?

Yes. Free for as long as Alpha runs.

Why free? You're early. Polaris is still being built, and your feedback shapes what it becomes. You get Coach first; we get honest answers. That's the whole deal.

What comes next: every Alpha member moves into the Beta. Polaris will be paid eventually, likely around $29.99 a month, with founding-member pricing for early members. You'll never be charged unless you choose to sign up.
