Getting better at tennis shouldn't cost $100 an hour.
Lessons are expensive
Private coaching runs $100 or more an hour, so most players get real feedback a few times a year at best.
Videos can't see you
A tutorial shows the perfect forehand. It can't tell you what yours is doing wrong.
Practice without a plan
Hitting without structure repeats the same mistakes. Beginners give up, and improvers plateau.
From the baseline to better, in four steps
- 1
Prop up your phone
Lean your iPhone on a water bottle just outside the sideline. A guide shows where it goes, and a ding tells you you're in frame.
- 2
Hit a 10-minute drill
Rally counts every stroke in numbers you can read from the baseline, and stops by itself at the rep target. A chime says you're done.
- 3
See every stroke
Get a score, the main thing to fix, and a clip of each stroke with the body part behind the mistake highlighted.
- 4
Follow your plan
Your next drill is already lined up. Redo any drill to see whether the fix stuck.
A plan that knows what's next
Tell Rally your level and how many days a week you play. It lays out phases, weeks and sessions, each a short mix of drills and exercises.
- Plans for Novice, Beginner and Intermediate players
- Built around the days you can actually play
- Stopped halfway? Pick up right where you left off
Watch the good strokes add up
Every drill is saved with its score and clips, so you can see the fix taking hold, week by week.
- Sessions this week against your goal
- Your share of good strokes
- Every past drill, with its score and stroke clips
Everything a coach would notice
A plan for your level
Novice, Beginner or Intermediate, set to the days a week you play.
Feedback on every stroke
Each stroke is judged on its own: contact point, swing path, shoulder turn and more.
One thing to fix first
Mistakes are grouped by their root cause, so you work on what's behind them.
Drill library
Practice any drill outside your plan, each with a tutorial video and a setup guide.
Progress you can see
Weekly consistency, your share of good strokes, and every past drill.
Analyzed on your phone
Body tracking, measuring and judging all run on your iPhone.
Hands-free cues
Sounds guide setup and tell you when you're done, so you keep your eyes on the ball.
Apple Watch, if you have one
Wear it on your racket wrist and Rally uses it to confirm each hit.
No sensors. No smart racket. Just your iPhone.
Smart rackets and clip-on sensors came and went. Rally needs only the phone in your bag and something to lean it on.
Questions
What do I need?
An iPhone, a court or a wall, and something to lean your phone against, like a water bottle. An Apple Watch is optional.
Which strokes does Rally coach?
The forehand, to start. More strokes are on the way.
Is it for beginners?
Yes. There are plans for Novice, Beginner and Intermediate players, and your plan comes from the level you pick.
How long is a session?
Each drill takes about 10 minutes, and a session is a few drills and exercises.
Where is my video analyzed?
On your phone. Rally tracks your body, measures each stroke and judges it on your iPhone.
Do I need an Apple Watch?
No. If you wear one on your racket wrist, Rally uses it to confirm each hit.
