I just migrated a React Native app to @expo that has been in production for 7 years
So nice so see 186k (!) lines deleted from the project!
This is mostly because of CNG which auto-generates the ios and android folder, so that I could remove them from git

The model predicts the angle of the hour, minute and second hands, which I again translate to a timestamp.
The model is exported as .tflite and used in my app through the amazing react-native-fast-tflite by @margelo_com!

Detection of time from analog watch achieved🤖⌚️
1. Live on-device watch detection
2. Take image and crop around the watch
3. On-device custom made ViT model for detecting the time shown on the analog watch

Now users will have a better default value when measuring their watch!

[Alfred Lieth Årøe @appfr3d]

The time detection model is based on a pre trained timm model from @huggingface, and fine tuned on a large image dataset of watches I have created with my app

Made this video with @halogenrecorder btw, pretty easy to use!

And here it is implemented in the app! 📱

Object detection model (trained on self-labeled, anonymized data from users) detects the watch ➡️ camera focuses on the center of the detection.

After the image is taken, a final detection is done to crop around the watch 👌

🔎Auto focus on a object

Today I trained an object detection model to find wrist watches with @ultralytics YOLO, imported it in a fresh @expo app, an hooked it up with react-native-vision-camera and react-native-fast-tflite from @margelo_com

Auto-focus on watches achieved👌📸

[Alfred Lieth Årøe @appfr3d]

I wanted to create this setup to improve the experience in my app, https://t.co/uf76mv5Q2V, so that the camera always focuses the watch.

This will give my users the clearest possible image for checking the accuracy of their watches ⌚️

@chrfalch Looking forward to a React Native world without Cocoapods and Ruby 🤩

[Alfred Lieth Årøe @appfr3d]

So basically Margelo and callstack saw Lynx and said “let’s make it a react native package”

[Margelo @margelo_com]

We just released react-native-runtimes! 🥳
👉 Render React components on separate JS Runtimes
👉 Share state (Zustand) across Runtimes, synced in C++
👉 Dual-Thread-approach for rendering/business logic
We plugged this into MetaMask which made the app start substantially faster:

@chribjel Si ifra hvis du trenger hjelp med å få den publisert! 🚀

[Alfred Lieth Årøe @appfr3d]

@Dimillian Works even better with Xcode’s built in MCP

[Alfred Lieth Årøe @appfr3d]

Great article about the paradox here https://t.co/h8jpLmYAhK

[Alfred Lieth Årøe @appfr3d]

Ever wondered why AI performs poorly when asket NOT to do something? Its because of "The Pink Elephant Paradox"... 🐘🩷

[Alfred Lieth Årøe @appfr3d]

npm packages should come bundled with agent instructions

Pro tip for all Codex users:
use the built in imagegen skill in Codex to have it create images fitting you product based on the color scheme and the style in you codebase!🖼️

Just used it for my new pay wall:
https://t.co/U15oni7yGo

[Alfred Lieth Årøe @appfr3d]

Doing an experiment where I upgrade my pay wall with these changes:

1. Feature aware: first shown premium feature is the on the user actually pressed

2. Generated feature image: showcase feature better

3. Less legal writing: use links instead

What would you change?

[Alfred Lieth Årøe @appfr3d]

Do you think my new paywall will convert better? What would you change?

First ASO experiment: translate to 15 languages🌐

People more often search in their native language, so localizing the app makes sense for better reach.

[Alfred Lieth Årøe @appfr3d]

New app alert! 📲 A bit crowded marked for this one, so I am going to treat this as an ASO experiment 🧪

[Alfred Lieth Årøe @appfr3d]

First 7 days for my new app 📊 How am I doing?

At least the baseline is set, now the ASO work begins…
