### 5/5 — 好用

*2026-08-27*

挺好用的

**Developer response:** 谢谢！更多改进和新功能正在开发中，敬请期待！

### 5/5 — 추천합니다!

*2026-08-21*

수면과 건강 데이터를 체계적으로 관리할 수 있는 앱을 찾다가 Fit Rest를 사용하게 되었습니다.
수면 시간과 수면 단계, 심박수, HRV, 회복 상태 등 다양한 건강 데이터를 한눈에 확인할 수 있고, 단순히 숫자만 보여주는 것이 아니라 이해하기 쉽게 정리해주는 점이 마음에 듭니다. Apple Health와 연동해서 여러 건강 데이터를 종합적으로 확인할 수 있다는 점도 편리합니다.
특히 Apple Watch를 함께 사용하면 더 다양한 데이터를 활용할 수 있지만, Apple Watch가 없어도 iPhone만으로 충분히 사용할 수 있다는 점이 좋았습니다. 자신의 환경에 맞게 선택해서 사용할 수 있는 유연한 앱이라고 생각합니다.
개발자분이 사용자 의견에 적극적으로 귀 기울이고 지속적으로 업데이트하는 모습도 인상적입니다. 앞으로도 꾸준히 발전해서 더욱 좋은 건강 관리 앱이 되었으면 좋겠습니다.
수면과 건강 데이터를 한곳에서 편리하게 관리하고 싶은 분들에게 추천합니다. 👍

**Developer response:** 소중한 리뷰 정말 감사합니다! Fit Rest를 좋게 봐주셔서 큰 힘이 됩니다. 현재도 더 많은 기능과 개선 사항을 준비하고 있으며, 앞으로도 계속 더 나은 앱으로 발전시켜 나가겠습니다. 감사합니다!

### 5/5 — 太完美了

*2026-08-19*

要是有个手表表盘丰富功能就更棒了

**Developer response:** 非常感谢您的支持！丰富 Apple Watch 表盘和复杂功能已经在计划中了，未来的更新会逐步加入。感谢您的建议！

### 5/5 — Love this app!

*2026-08-19*

Very well made, with detailed and useful information! Absolutely love this app so far.

**Developer response:** Thank you so much! I’m really glad you’re enjoying Fit Rest and finding the insights useful. Many more improvements are on the way!

### 5/5 — Wow

*2026-08-17, version 3.21.0*

This app has it all for the health conscious individual. The layout is really nice. The app goes into a lot of details with each stat you can track.

### 5/5 — Great program

*2026-08-16, version 3.21.0*

Excellent program, and just keeps getting better. Lifetime subscription is certainly worth it. I have multiple health programs, and this is always the one I look at first.

### 5/5 — Excellent App!

*2026-08-16*

This is a great app with tons of information about health and recovery. There is so much to dive into and so many meaningful metrics to see how you are doing after sleep/working out etc. if you like apps like Athylitic or Bevel then this app is a very worthy alternative especially as the developer has provided for a lifetime purchase option which many now do not. This is one of a series of extremely useful apps from this developer who also has a great eye for producing beautiful visuals and excellent information!

**Developer response:** Thank you so much for the thoughtful review and support! I’m really glad you’re enjoying the depth of the health and recovery insights, as well as the lifetime option. Many more improvements and new features are already in progress!

### 5/5 — A Truly Outstanding Wellness Companion

*2026-08-15*

Fit Rest is one of those rare apps that gets so many things right that you wonder how you ever managed without it. The way it presents all your essential wellness data is nothing short of beautiful — clean graphs, intuitive layouts, and insights that feel genuinely helpful rather than overwhelming. Everything is right where you expect it to be, and the visual design makes checking your daily progress almost enjoyable.

One feature that stands out is the Body Battery. The insight it provides is remarkable: you can instantly understand how your sleep, stress, and activity levels combine to affect your overall energy. It’s not just data — it’s a meaningful snapshot of how your body is actually doing, and it’s presented with clarity and elegance.

I also reached out to the developer with a question, and the response came promptly. That level of support says a lot about the care behind this app. It’s reassuring to know the team is attentive and committed to improving the user experience.

A few more things I appreciate:

• Daily Trends — seeing patterns over time helps you make smarter lifestyle adjustments.
• Sleep Analysis — detailed but easy to digest, perfect for anyone trying to improve rest quality.
• Stress Tracking — helpful for understanding how your day affects your body.
• Clean Interface — no clutter, no confusion, just thoughtful design.

Overall, Fit Rest is a well‑crafted, reliable, and insightful wellness app. If you’re looking for a tool that helps you understand your body better and encourages healthier habits, I highly recommend giving it a try

**Developer response:** Thank you so much for the incredibly kind words and support! I’m really glad you’re enjoying Fit Rest and finding the insights useful. Many more improvements and new features are already in progress and will be coming soon!

### 1/5 — Nur Apple Watch ☠️
