01Scheduled day
Open the plan
See the scheduled workout and nutrition plan. If notifications are enabled and the schedule qualifies, a reminder can help the client arrive prepared.
The client experience
One app for the work between check-ins.
Your clients should not need one app for workouts, another for food and WhatsApp for the actual coaching. CoachOS keeps the plan, the conversation and their progress together.

For invited clients
Your coach sends the invitation. The app takes you to the plan.
CoachOS is the client app for a coaching relationship that has already been set up. The invited email connects the right client to the right coach before any plan is shown.
Official listings
Both links resolve to CoachOS Ltd’s current client-app listings. Device, OS, country and store-account eligibility still apply.
- 01
Open the invitation from your coach
CoachOS access starts with a coaching account. Keep the invitation and use the exact email address your coach used for you.
- 02
Download the official client app
Choose the verified App Store or Google Play listing for your device. Store availability still depends on device, operating system, country and account eligibility.
- 03
Confirm your coach and finish setup
Enter the invited email, confirm the coach shown, create a password if the account is new and complete the guided profile, schedule and intake steps that apply.
- 04
Open the first assigned session
Training, nutrition and the coaching conversation appear according to what the coach has assigned. Optional reminders and connections can be skipped or managed later.
Reminder boundary
Helpful when enabled. Never a condition of using the plan.
Workout and coach-message notifications require client permission and an active registered device. Schedule reminders also depend on an eligible workout day and timing; a specific workout time can support a pre-workout reminder. Calendar sync and health connections are separate optional choices. Exact delivery is not guaranteed under every device or network condition.
The weekly rhythm
Set up once. Keep returning to the same clear plan.
After onboarding, CoachOS gives clients one familiar place to understand the next session, record the work, stay close to their coach and carry context into the following week.
02Training
Log the session
Follow exercises, record sets and reps, use rest guidance and keep moving through the workout.
03Between sessions
Keep the coach close
Send a message, voice note or image without taking the coaching conversation into another app.
04Check in and repeat
Carry context into next week
Complete the configured check-in, review goals and trends, then return to the next assigned week without starting again.
Training that is easy to follow
Open the session and know what to do next.
Exercises, sets, reps and rest guidance live inside a focused training flow. Clients record the work as they go, so the coach sees what happened rather than chasing an update later.
- Clear session structureExercises and coaching detail in the order they are needed.
- Simple set loggingRecord weight, reps and completion from the gym floor.
- Smart schedulingMissed sessions can shift forward while workout days stay fixed.

Nutrition that fits the coaching method
Prescribed when it needs structure. Flexible when it needs freedom.

The You page
Progress should be easier to see than to remember.

Connected health context
Useful signals, shared on the client’s terms.
Apple Health and Health Connect can add supported device metrics such as steps. Approved WHOOP test members can connect recovery, strain, HRV and sleep while general production access remains under provider review. Client-controlled cycle sharing can add context when the client chooses to provide it.

Works around real life
Log now. Sync when the connection returns.
CoachOS is built for the moments when the gym Wi-Fi is not. Offline-first logging lets the client keep moving, with automatic sync when the app reconnects.

Questions, answered
Client app questions
Which phones can clients use?
The official CoachOS listings are live on Apple’s App Store and Google Play. The links were checked on 19 July 2026; installation still depends on the client’s device, operating system, country and store eligibility.
I have been invited. Which email should I use?
Use the same email address your coach used for your CoachOS account. The app uses it to find your invitation and confirm the coach you are joining.
What if CoachOS cannot find my invitation?
Check the spelling and make sure the email matches the address your coach used. If it still is not found, ask your coach to confirm the account email or finish setting up access.
Do clients have to enable reminders or connect health data?
No. Notification permission, calendar sync and supported health connections are optional. Clients can skip them during setup and manage available settings later; reminder delivery also depends on an eligible schedule, an active device and the relevant permissions.
What can clients do inside the app?
Clients can follow workouts, log sets and reps, use their nutrition plan, view recipes, complete check-ins, track progress, message their coach and connect supported health data.
What happens if a client misses a workout?
With Smart Rest Days enabled, the scheduled workout days remain fixed while the missed session moves to the next workout day. This keeps the programmed sequence intact.
Can clients share WHOOP and health data?
Apple Health on iOS and Health Connect on Android are available with client-controlled permissions. WHOOP can provide recovery, strain, HRV and sleep context for approved test members while general production access remains under provider review.
Can clients control what health information is shared?
Yes. Health connections and sensitive information such as cycle data are client controlled and depend on the permissions the client chooses to grant.
Does workout logging work with a poor connection?
CoachOS is designed with offline-first logging and automatic sync, helping clients keep recording their work when the connection is unreliable.
A better client experience
