What's New in Fit Rest

3.29.0

September 8, 2026

24-hour clock • Times now follow your region and the system 24-Hour Time setting - in the app, in the widgets, on the watch and on every chart • Fixes screens that mixed the two clocks, like the wake time above the Chronotype timeline Water • Log up to 40 oz / 1200 ml at once, so a large bottle fits • Round amounts no longer show a needless decimal Faster • Cardio Load and its zone breakdown open quicker and stay smooth while you scroll or change the range Heart • Estimated Fitness Age redesigned - the number, its notes and the explanation now sit together Widgets • The Steps and Sunlight tiles now read your latest data themselves instead of waiting on the app • Every tile turns over at midnight, so none of them can still show yesterday's totals Also • Fixed a number pad that could stay on screen after you moved on Thank you for using Fit Rest!

Best I’ve used!

I currently have SEVEN 3rd party sleep related apps on my phone. This one ticks all the boxes and does it beautifully! I think it almost knocks off one of the most popular sleep app suites ( Autosleep and Heartwatch) . It clearly would, for me, if only it included my Apple Watch sleep stages graph. This OS the only big omission I miss each day. Maybe it’s buried in there but I haven’t found it. Great job!

Response from developer

Thank you so much for this thoughtful review! It truly means a lot, especially knowing you've tried so many sleep apps. More detailed sleep analysis, including Apple Watch sleep stages and graphs, is coming in the next version!

Beautiful app

I am using it everyday
i love the apple watch compilations

Please add water goal with easy water intake value entry on tapping the compilation

Response from developer

Thank you so much! I'm glad you're enjoying the app and its Apple Watch complications. A water goal and quicker water intake entry from the complication are great suggestions. I'll work on it soon!

鲜明

非常好看的界面,要是能有苹果表盘就更优秀了

Response from developer

感谢您的支持!Apple Watch 表盘复杂功能已经添加,更多改进也正在进行中!

Great App!

A great app so far, clean and simple. 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!
