After sharing [til.re](https://news.ycombinator.com/item?id=46483121) (a minimal countdown timer) here, I built another small tool: cross-device text transfer without accounts or apps.
*How it works:*
1. Go to `tmp.tf#yourchannel` on one device
2. Paste your content
3. Open the same URL on another device — done
The channel name is the password. Use something like `#a9$Kx2m` for private transfers, or `#meeting-notes` for easy sharing.
*Features:*
- URL-as-state: the channel name lives in the URL, easy to share
- Auto-expires (no manual cleanup)
- Works in any browser
- Deployed on Cloudflare edge network
I also made a dark-themed version at *copypa.st* if you prefer that aesthetic.
Built this because I got tired of emailing myself links just to move a snippet from phone to laptop.
I built til.re because I was tired of timer apps that require accounts, downloads, or complex setup.
*What is til.re?*
It's a minimalist countdown timer where the URL IS your state. Just type what you need directly in the address bar:
- til.re/25m → 25-minute countdown
- til.re/pomodoro → 25m work + 5m break loops
- til.re/17:00 → countdown to 5 PM
- til.re/2026-01-05 → countdown to a specific date
*Features:*
- No signup, no app, no accounts - just instant timers
- Beautiful themes: zen, neon, matrix, and more
- Shareable via URL - send a timer to anyone
- Semantic shortcuts for common durations
- Loop mode for productivity sessions
- Works on any device with a browser
*Tech:*
Built with vanilla JS, hosted on static CDN. The entire state lives in the URL, so there's nothing to store.
