Questions & Answers

As answered by people managing PhysMo and RallySteps.

What makes your product unique?

RallySteps's answer:

Most kids tennis apps are arcade games or video analysis for older players. RallySteps is real home practice for kids 4 to 12: a fresh ten-minute plan each day, every move shown as an animation, and a coach voice that runs it out loud so a child can practice without a parent coaching. The drills follow the home practice tennis federations give young players, from red ball to green ball.

Why should a person choose your product over its competitors?

RallySteps's answer:

It's built for young players, not adults: red, orange and green ball stages, short cards and a voice that counts and encourages. It's in the App Store's Made for Kids category with no account, no ads and no tracking, and it works offline. The first week is free with everything open, and 2 cards a day stay free after that.

How would you describe the primary audience of your product?

RallySteps's answer:

Parents of kids aged 4 to 12 who take tennis lessons and want the days between lessons to count, from first red ball taps to green ball serves and volleys, and coaches who want to give families a simple plan for home.

What's the story behind your product?

RallySteps's answer:

RallySteps was made by a tennis dad. His daughter loved her lessons, but the days in between didn't count, and he didn't know enough to run good drills himself. So he built a ten-minute daily plan she could follow on her own, and tested it with her at home.

Which are the primary technologies used for building your product?

RallySteps's answer:

A native iOS app in Swift and SwiftUI. Everything runs on the phone: the drill animations, the built-in coach voice, and Wall Rally, which counts hits by sound. Subscriptions use Apple's StoreKit, and there are no third-party SDKs.
