You bring the fire. Bellows feeds it.

Lift, run and ride, solo or with a partner. On iPhone and Apple Watch.

Your AI. Your Plan. Your Goal.

Every rep, every mile, one log. Bellows™ keeps your lifting, running, riding and the rest of your training in one place, so you see your whole week together.

Today screen: today's planned long run, the connected AI and its last change, the weekly goal, the muscle recovery map and what's coming up — Today at a Glance

Logging bench press mid-workout: last time's numbers, plates per side and the rest timer — Fast Logging Mid-Workout

A 16-mile long run with its route, pace, climb, heart rate, calories and mile splits — Every Mile, Split by Split

Calendar week view: hard sets by muscle group, miles against the week's target, and each planned lift and run marked done — Your Week, Planned

Progress tab: level and points, a three-week streak and the muscle recovery map — Your Progress

Bellows on Apple Watch during a run: time, heart rate, distance and pace — On Your Wrist

Lift, run, ride, swim. One log.

Strength sessions, runs, rides, swims, rows, hikes and hybrid race simulations in one week, with sets, reps and miles side by side and last time's numbers ready.

Your AI. Your Plan. Your Goal.

Use the AI assistant you already trust. It can read your training, build a plan and put it on your calendar. Ask for 6 × 800 m and the steps go straight into the run recorder. Every change is labeled, you can have changes wait for your OK, and Undo takes any of them back.

Train with a partner.

Log for two on one phone, each with their own weights and rest.

Train from your wrist.

Lift from Today's plan or a routine with a rest timer, or start a run, walk or ride on Apple Watch and see distance, pace and heart rate as you go.

No distance ceiling.

Set up a marathon, a 100-miler or a 24-hour race as a training block, split into base, build, peak and taper. A mindset and a lifestyle, not a distance.

Bring your history.

Import from Strong, Hevy or StrengthLog, runs and rides from Garmin, Strava, Coros or Suunto files, and workouts from Apple Health. Anything else, your AI can convert. Export any time as CSV or JSON.
