Keep moving forward, I use it everyday and addicted to it a little bit 😄. My personal opinion- whatever the team decides to do with the app ( updating with features etc) It’s imperative to keep the UI/UX simple to use, interactive and IOS design based. Another tip, if there’s a free trial that we can use to see the pro features that would be nice too. But overall the free section is amazing! **Developer response:** Thank you so much for the wonderful review and for using the app every day! Keeping the UI clean, simple, and true to iOS will remain a priority as the app grows. I also appreciate your suggestion about offering a free trial and will consider it for a future update. Thanks again for your support! ### 5/5 — 很好用 *2026-09-03* 帮 **Developer response:** 感谢您的认可！更多改进正在进行中。 ### 4/5 — 小组件里面的各项指标提示能改成中文吗，或者增加一个中文切换选项 *2026-09-01* 中文，中文，中文 **Developer response:** 当然可以！您可以将缺少中文翻译的页面截图发送到支持邮箱吗？我会尽快添加。 ### 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. ## Frequently asked questions about Fit Rest ### What does FitRest do?
