Lost my phone at the office and spent 30 minutes turning the place over. Find My was disabled by MDM. Out of ideas, I asked Claude how I could find it. It suggested tracking the Bluetooth signal strength, then wrote me a meter in about a minute. I walked around watching the number climb. Found it. Apparently you can just make the tool you need now. Code:

@deedydas
many people asked me how i keep shipping when on my phone i have my own ios app and here’s a quick clip of how i use it: - ssh to my mac mini - never open the mobile keyboard - it sucks. instead i designed this touch “dial” - voice input for prompts using on-device transcription model - i can also send images directly from phone do you like this kind of interactions? i actually had to design the “dial” myself. both fable and sol failed to come up with this solution - they kept building different button rows. fable called me clever when i showed it this idea :)

@Shpigford
VERY COOL!! Thanks @jordandotbuilds for the tip, I can now test my iOS app on web I asked Claude Code to set up serve-sim, a web-based iOS simulator that can stream the iOS app my Claude Code on VPS built live to me, because it's on some Mac Mini in the cloud without even a GUI (it's headless) I cannot actually try it on the Mac itself! Before Claude would make me a page with screenshots but I had no idea how the app felt, now with this it works This is hosted on the Mac Mini via SSH (it shows localhost but it's a tunnel via SSH to the Mac Mini), bit laggy but nice!
