## What is String GOAT?

Your strings lose tension every day. String GOAT tells you when it matters. Log every restring, track your tennis sessions with Apple Watch or Galaxy Watch, watch your string's predicted lifespan, and get AI string recommendations built on your own play data.

Record on your watch, analyze on your phone, manage on the web. From Apple Watch and Galaxy Watch to the web dashboard, your entire stringing workflow flows seamlessly across devices.

Built for tennis players who notice a single pound of tension, home stringers who string their own rackets, and coaches and stringers who manage more than one.

### 3/5 — Bug fix: scroll on racket number broken

*2026-05-01*

When adding a new racket I can’t select any rackets except for 1 - please fix!

Otherwise enjoying the app - would be nice to have autocomplete for string names and brands

**Developer response:** Hi glee17637, thanks for the review!

On racket selection — That's the intended Free Plan policy, not a bug. Free accounts get unlimited records for one racket (#1), and tapping #2–5 triggers the Pro upgrade dialog, which can look like the selection is unresponsive. We'll make this clearer in future updates.

On autocomplete — The app already recalls your previous entries with one tap. A full brand/string database for autocomplete is a good suggestion, and we've added it to our backlog.

Appreciate the detailed feedback!

### 5/5 — 잘 봤습니다!

*2022-12-24*

재미있는 앱 이네요! 

- 내 피지컬 정보 (성, 연령, 키, 몸무게)
- 라켓 종류(패턴, 크기, 무게) 그립 사이즈, 그립 타입
- 백핸드/ 플레이 스타일, 구력

위와 같은 정보들을 기입하게 해 유저가 나와 비슷한 유형의 플레이어들이 선호하는 스트링의 종류, 믹스매치, 텐션 정보를 추천 해 주는 서비스가 되면 추후 버티컬 커머스로 성장 할 수 있을 것 같습니다.

**Developer response:** 안녕하세요, kennytennis 님!
앱에 관심 가져 주셔서 정말 감사합니다.
라켓과 스트링 관리에 불편함을 느껴 단순히 이를 해결하고자 개발한 앱이다보니, 사용하시는 분들 입장에서 추가하고 싶은 기능이나 아쉬운 부분이 많이 있는 것 같습니다.
저 역시 뼈저리게 느끼고 있습니다^^;
진심 어린 조언 해주셔서 정말 감사드립니다.
저도 언젠간 말씀해주신대로 하나씩 이루어지길 바랍니다.
감사합니다:)
