Meet Charly. It remembers every match, practice, and night of sleep you log, then tells you exactly what to work on next. Any hour, on or off the court.
Proactive coaching
Most coaching apps wait for you to open them. Charly notices what just happened — a night of sleep, a finished session, a match you mentioned — and reaches out when it matters. No prompt needed.

Yesterday's question is still waiting
Charly following up
now
Still thinking about Saturday? One idea for your next session: start with ten minutes of crosscourt forehands to groove the new cue.
Example messages. Charly writes every check-in from your own logs and conversations.
Automatic logging
Connect Apple Health once. Workouts, sleep, steps, and heart rate sync in on their own from Apple Watch, WHOOP, Oura, Garmin, and other apps that share with Health, so Charly always has the full picture.

Charly reads it all
What syncs depends on what each device shares with Apple Health. Apple Watch and Apple Health are trademarks of Apple Inc. WHOOP, Oura, and Garmin are trademarks of their respective owners; FlowState is not affiliated with or endorsed by them.
How it works
One tap brings in workouts, sleep, steps, and heart rate from Apple Watch, WHOOP, Oura, Garmin, and more.
Your sessions and recovery log themselves. Add a match score in a couple of taps, or just tell Charly.
Charly reaches out at the right moments with what your data means for today, and answers anything you ask.
Log & track
Workouts arrive from your watch with heart rate and energy already filled in. Add a match score in a couple of taps, or just tell Charly.
Follow-ups that remember
Tell Charly about Saturday's league match or Thursday's lesson. It keeps the plan in mind, checks in when the time comes, and offers to log how it went.
Photo feedback
Send Charly a photo from the court and get feedback on what's actually happening: contact point, balance, toss. Then one simple cue to take into your next session.
Between lessons
Nothing beats time on court with a great coach. But lessons end, schedules clash, and it rains. Charly is there for everything in between, and when you log your lessons, it helps you keep working on exactly what your coach is teaching.

Apple Health access is read-only, and you can delete your account and data from inside the app whenever you like.
Anything that shares data with Apple Health. That includes Apple Watch, plus WHOOP, Oura, Garmin, and other devices through their apps' Apple Health connections. FlowState reads workouts, sleep, steps, heart rate, active energy, and weight, read-only. What comes through depends on what each device shares with Health.
Around real moments: when last night's sleep syncs, after a practice or match is logged, when a plan you mentioned comes due, and once to follow up on a question you haven't answered. It holds off while you're mid-conversation, and you can turn notifications off anytime in iOS Settings.
Less than you'd think. Workouts, sleep, and recovery import on their own. Matches take a couple of taps to add the score and opponent, or you can just tell Charly and it will log it for you.

No. Time on court with a great coach is the best way to improve, and FlowState is built to work alongside it. Charly covers the hours in between: the night before a match, the solo practice, the week you couldn't book a lesson. Log your lessons and Charly will help you keep working on what your coach taught.
Your logs and conversations are used to coach you. You can delete your account and its data from inside the app at any time. Our Privacy Policy explains exactly what we collect and why.
Not yet. FlowState is available on iPhone.
Connect Apple Health, play your next session, and let Charly take it from there.
