Tracking workouts on mobile

The hi.fitness mobile app has a workout tracker built for the gym floor: one exercise at a time, big touch targets, and everything saved on your phone as you go - so a closed app, a dead battery, or no signal never costs you a set.

Starting a workout

Everything starts from the workout card on your dashboard:

• Start - opens today's planned workout with every exercise, set, and target weight already filled in.
• Start free workout - pick one or more exercises to begin with, then build the session as you go.

On a rest day, or when you have no plan, the card offers a free session instead. You can also start a free workout from the Workout tab.

Logging your sets

The current set sits in the highlighted card at the bottom of the screen:

• Tap Reps or Weight to open the number pad. Use the step buttons for quick adjustments, then Done.
• Tap Save set to log it and start your rest.

The card above lists all sets for the exercise - tap any row to jump to that set, and Add set puts an extra one at the end. To remove a set, press and hold its row.

Rating how a set felt

Next to the set number is a face showing how the set went. Press it and three faces lift out of it - slide your thumb onto the one you mean and let go:

• 😅 the set was easy
• 😌 it went as expected (this is the default)
• 🥵 it was a struggle

You never leave the workout screen, and the face stays on the set row so you can see at a glance how each set went. Ratings feed your session summary and help your trainer see where a weight is too light or too heavy.

Voice memos

Mid-workout is a bad time to type. An exercise note can be spoken instead, and the recording is kept with the workout so you can play it back later.

Tap Note under the exercise name, then Add voice note, and tap Stop when you're done. The recording collapses into a single line with a play button and its length - tap it to listen back, press and hold it to replace or delete it. A note can have both text and a recording, or just one of them. An exercise that carries one shows a small microphone icon, so you can see at a glance where you left it.

Recordings are made on your phone, so they work with no signal - you can record and replay them in a basement gym. They upload on their own once the workout has been saved and you have a connection, and they show up under Voice notes when you open the finished workout from your history.

Rest timer

Saving a set starts the rest countdown at the bottom of the screen. From there:

• +30s adds more rest.
• Next set takes you straight to the following set.
• Next exercise appears once an exercise is done - or Finish workout on the last one.

You don't have to wait: the next action is always available, and the timer lets you know when rest is over. And when a set is a new personal best, the timer flags it right away with New best.

Coach nudges

If your rest has been over for a while and you haven't touched the workout, the app gives you a gentle "Ready for your next set?" - like a trainer would, and only when you've actually drifted off, never during the rest itself:

• In the app, the heart-rate bubble shows the reminder with a light tap, and only while your heart rate says you're not already working.
• In another app - watching a video, changing your music - hi.fitness sends a single notification instead. Tap it to come back. The app asks for notification permission once, at your first rest; if you decline, this stays off (you can change it anytime in your phone's notification settings).
• On your Apple Watch, with the watch workout running, the reminder arrives as a tap on your wrist with the same message under the timer - handy when your phone is in a locker. When the watch is on your wrist, it takes over and your phone stays quiet.

Logging a set, adjusting the rest, or finishing the workout clears the reminder on every device.x

Exercise details, history, and swapping

The buttons under the exercise name open:

• Details - the exercise demo video (tap for full screen) and description.
• History - your overall best, progress trend, and previous workouts for this exercise.
• Note - a note for this exercise, typed or spoken.
• Swap - replace the exercise for this workout only. If you already logged sets, you can keep them and replace just the remaining sets.

Tap the Exercise X of Y counter at the top to see the whole workout: hold the handle to drag exercises into a new order, or open a row's menu to swap or remove it. Add exercise opens the library - search, filter by muscle, or pick from Recently used. Can't find what you need? Create your own exercise with a name and a primary muscle, and keep logging.

During a free workout, the library also shows exercises tuned to your workout. It considers the sets you completed, how they felt, movement variety, muscles already involved and your recent workouts. Close copies are moved down once an area has enough work. When the session already has enough useful volume, it may suggest finishing instead. These are suggestions only - you can always search for and add any exercise.

Finishing and records

Tap Finish to review the session: total volume, completed exercises and sets, your time, and optional energy burned - tap either to adjust. Then Save workout.

If the session set new personal bests, they're celebrated on the confirmation screen, each with the value you improved from. Either way, the workout lands in your training history and counts toward your statistics and records.

Offline and interruptions

The tracker is built to keep working without a connection:

• Progress is saved on your phone after every action. If the app closes, your battery dies, or your screen locks mid-set, nothing is lost - reopen the app and the workout is right where you left it.
• Leaving the tracker keeps the workout in progress. Back on the dashboard, the workout card shows an In progress badge with your set count and elapsed time - tap Continue to pick up exactly where you left off.
• Saving works offline too. Finish and save as usual; you'll see "Saved on this phone - it will sync when you're back online", and the app uploads the workout automatically the next time you have a connection.

One session runs at a time: opening the tracker while a workout is in progress always resumes that workout.
