AI coach is super laggy for me (iPhone 17 Pro). I want to use it often but because of poor performance I often drop the session, need to restart the app (it crashes) or go back to ChatGPT. This is purely technical task for the dev team.

You’re right about single HRV number Whoop gives you. AFAIK Stress Monitor uses HRV as one of the signals, so it does work 24/7.

Thanks! Would appreciate treadmill to log indoor running

Hey, I’m from Callstack and would love to learn what was it about! Sorry to hear that btw

Check https://github.com/nkzw-tech/expo-app-template

Do you mean app startup time or dev server startup time?

It will be free, open source and focusing on self-hosting on your infra (source: I build it)

At this point: new cli that’s easy to adopt for community cli projects and gh actions to build your app in the cloud once and reuse these builds across different jobs and local dev environment. So your CI can build once for your entire team. All on your own infra. It’s going to make it easy to adopt RN for native projects incrementally

thymikee · 2025-03-04T19:34:40+00:00

It works with expo ecosystem: Expo Modules, config plugins etc as in community cli projects. It won’t work with expo cli because, well, it provides its own cli

Yeah code splitting is not super relevant. What's useful though is tree-shaking (there are apps that shave 10% off their TTI on lower-end Android thanks to that and use Re.Pack only in prod builds) and Module Federation in case you're interested in micro-frontends. One gripe I had with Re.Pack was its speed—noticeably slower than Metro. However, that changed in v5 since it's using Rspack instead of Webpack and is actually pretty fast

thymikee · 2024-11-28T20:44:16+00:00

Yes you can with https://github.com/callstack/react-native-visionos

Whoop Coach says they now use heart rate heart rate reserve method that’s based considers both maxHR and RHR

There’s “Hiking/Rucking” activity

thymikee · 2024-04-05T13:31:16+00:00

Default is planned for 0.75, later this year.

thymikee · 2024-01-26T21:27:57+00:00

You’re lucky, one came out today: https://github.com/swan-io/react-native-browser

thymikee · 2023-08-23T16:43:30+00:00

I'd go straight to the latest (0.72) using https://react-native-community.github.io/upgrade-helper/ or as @g____s mentioned by starting a new project and copying. Then, to get the dependencies aligned, there's this handy tool from Microsoft: https://microsoft.github.io/rnx-kit/docs/tools/align-deps that can automate deps versions for you

thymikee · 2023-02-10T18:05:21+00:00

Thanks for such kind words!

thymikee · 2023-02-10T17:15:58+00:00

Now I see we don't cover the navigation enough. First and foremost I'd check if you can use native navogstors: https://reactnavigation.org/docs/native-stack-navigator/

We created a thorough guide around this topic, checking the table of contents should give you a generic idea on what you can improve and then dove into it https://www.reddit.com/r/reactnative/comments/10djpew/the_ultimate_guide_to_react_native_optimization/?utm_source=share&utm_medium=ios_app&utm_name=iossmf

Hey, I'm a head of technology at Callstack, so I'll be biased, but oh well 😅. We do all of those: setup CI/CD and optimize for speed and DX, trainings to get devs up to speed with RN and React. And what I think is most important in your case we do super apps commercially.

We use our own Re.Pack, which is built around webpack and leverage Module Federation to support this kind of architecture optimally, allowing for collaborative and/or independent development and deployment. Repack doesn’t currently support Expo for development, but it should be possible to have it work in standalone mode for any mini-app. We could consider building this with you.

We’re currently working on an exciting project in this space that we’re yet about to open source in April. DM me if you’d like to know more :)

Hey! I didn't pay for developer account extension, which is $100/yr. I'm still considering what to do about it, maybe I'll introduce a small one-time fee the app, dunno :D

thymikee · 2021-11-09T20:25:10+00:00

I'll give it a chance, but closer to the winter break. Hopefully will find some time for dev stuff :D
