Strength training
407 exercises, plus ready-made workouts, your own workouts and your own exercises. You start with your heaviest weight from last time and confirm set by set. Rest starts automatically and tells you when it is over. Link exercises into a superset, and the plate calculator shows the plates per side.
Training plans
Plans for strength, calisthenics, running up to marathon, cycling and climbing. Your plan moves on once you reach its goals, with a weekly goal and plan summary, and can be printed. Swap, remove or add exercises at any time. Build your own weeks as a split, with rhythm, days and start date.
Performance
Running and cycling with GPS: time, pace, distance, heart rate, elevation, weather and calories. The ghost ring shows live whether you are ahead of or behind your best on the same route. When running it appears after about 100 to 200 metres; when cycling the app also recognises known routes mid-ride. On Apple Watch this works with its own GPS and haptic pulses on your wrist.
Personal best
The app keeps your bests per exercise and sport, for strength with weight and 1RM. The ghost comes automatically from your earlier GPS runs and rides on the same route; there is nothing to pick. Runs only race runs, rides only race rides. Without GPS you correct the distance at the end. From that the app learns your pace per heart-rate zone and sets your best.
Analysis
The 3D figure shows how load is spread across your muscles. For each exercise you see bests and goals. A target weight or distance, with a date if you like, shows how much is left and whether you are on track. You also get training time, prior load and weather.
Replay
After every workout, or later in your history, watch your workout again in 30, 60 or 120 seconds. The replay shows the ghost of your best and the heart-rate comparison. Runs play on the map, with ghost, pace and heart rate.
Export
Export GPS runs and rides as a video in 9:16 portrait or 1:1 square. As a transparent overlay you can lay them over your own footage. Save all workouts as a CSV file and export your plan as a calendar file. Bring your history from Strong, Hevy, JEFIT, FitNotes or StrongLifts into the app via CSV.
Gym Buddies
Start a group, invite buddies by QR code, link or code. A private group holds up to ten people, a public one up to twenty. The feed shows workout start and end, confirmed sets and personal bests, even when you train in different places. Add reactions, comments and short voice messages, also from your Apple Watch.
Fall alert
When cycling, skiing, riding, in the mountains and climbing outdoors, the app reads acceleration and speed during your workout. If it detects a fall, a 60-second countdown starts. If you don't tap “I'm fine”, your emergency contacts get a text with your location. Each contact agrees beforehand via a link. The feature is optional, needs mobile network and a phone on your body, and does not replace emergency services.
Climbing
Bouldering, lead and top rope, indoors and outdoors, each as its own exercise. Pick your gym, set the grade, climb and tick it off. The app remembers the scale per gym; on rock your own applies. The pyramid shows what you have done at which grade.
X-Hybrid
The whole race: 8 × 1 km and the eight stations. Competition mode runs it in one go, with the time per section and your class. The watch leads, the phone can stay away. In the partner race one person starts, both confirm the sections and the time runs the same for both, each in their own class.
Personal area
A QR code from the app connects your browser. On the big screen you see your workouts, bests, groups, feed and profile, and you can react and comment. In the planner you build day, week and month, with times, and send the plan to the app. The calendar subscription brings sessions into your calendar. The area is part of the full version.
On your watch
Apple Watch and Wear OS. Your planned workouts and favourites are on the watch, one tap on start is enough. The phone can stay in the locker; back at the phone everything is taken over. Watch and phone show the same state during a workout. Heart rate comes straight from your wrist, and the watch can take over the look from your phone.
Foldables
iPhone Duo and Android foldables. Folded, you use the app one-handed. Unfolded it uses the whole screen: controls on the left, heart rate and ghost on the right. Half open, the device stands like a laptop, display on top, buttons below. Buddies, replay and workout comparison use the full width too.
