Holt: Sleep, HRV & Training

Holt keeps your workouts and your health in one place, whether or not you own a fitness watch.

Record a run, walk, ride or hike straight from your phone and get a route map, distance, pace, splits and elevation as soon as you stop. Wear a Garmin? Link it once and your device activities show up here too, right next to the ones you tracked on your phone.

WORKS ON ITS OWN, BETTER WITH A GARMIN
The core is all phone based: GPS tracking, strength training, your full activity history, fitness tests. Connect a Garmin and Holt fills in everything around the workout: sleep, resting heart rate, stress, Body Battery, HRV, VO2 max, respiration, pulse ox and skin temperature.

TRACK EVERY ACTIVITY
- Live GPS for runs, walks, rides and hikes, tracked with the screen off
- Route map, splits, pace and elevation on every session
- Heart rate zones when you pair a strap or watch
- Put two activities side by side to see what changed
- Built-in fitness tests, including the Cooper and Rockport

STRENGTH TRAINING, NO WATCH NEEDED
- Build routines with supersets, rest timers and target reps
- Follow a guided session one set at a time
- Plan the week in front of you, or the months ahead
- Send a whole plan to your Garmin so it shows on your wrist

YOUR HEALTH, AT A GLANCE
- Sleep, resting heart rate, stress, Body Battery, HRV, VO2 max and more, pulled straight from Garmin
- A daily readiness view that tells you whether to push today or hold back
- Full history for every metric, not just the last week
- Step and intensity-minute goals followed across the whole week

BUILT TO STAY OUT OF YOUR WAY
- No ads, and no selling your data
- An account is optional. Record for months without making one
- Add an account when you want your history backed up or on a second phone
- Light and dark themes, with a few color options

Holt is a tool for training and nothing else. If something is missing or broken, tell us from Settings inside the app.
