Why Slight
A phone built for less. A world that runs on texts.
The Light Phone II is made to be used as little as possible, and typing a long reply on its small E‑ink screen takes patience. Everyone else still texts: the group chat planning Saturday, the change to school pickup, the friend who needs an address right now.
And texts aren’t only words. The Light Phone II can’t show you the photo from the birthday party or open the link to the sign‑up sheet. With Slight, photos appear right in the conversation, you can send your own, and links open in your computer’s browser.
Answer all of it from your computer’s keyboard, then close the window. Your phone stays simple, and nobody is left waiting on you.

-

Keep Slight in the menu bar or system tray and get a notification when a text arrives.
-
Light, dark and narrow
Follow your computer’s appearance or pick light or dark. Shrink the window to a phone-width column.
How it works
Your phone stays light.
No new launcher and no apps to open on the phone. Slight works alongside LightOS.
Install Slight
Download the app for your computer. On a Mac, drag Slight into Applications.
Set up once over USB
Slight guides you into EDL mode for setup: shut down your Light Phone II, then hold both volume buttons as you plug it in. Slight saves recovery files, adds your computer’s key and restarts the phone into LightOS.
Go wireless if you like
Pair over USB to keep texting over Wi‑Fi or cellular when the cable is out.
EDL mode is only for setup. Afterward, use your phone normally in LightOS—even while Slight is connected. LightOS stays your launcher and default messaging app; setup doesn’t replace it or the bootloader.
Privacy
Private by design.
Your messages travel between your computer and your phone. Nobody in the middle can read them.
- Encrypted end to endWi‑Fi and relay connections use AES‑256‑GCM with a key that’s set up over USB and stays on your devices.
- A relay that can’t readWhen you’re away, the relay passes encrypted data between your computer and phone and keeps no message history.
- No accountSlight doesn’t ask for an email address, a phone number or a Light sign-in.
- Metrics are opt-inOptional usage metrics are off by default and never include messages, contacts or notes.

FAQ
Questions
Which phones does Slight work with?
Slight is built for the Light Phone II (model TLP201) running LightOS. Other Light Phone models aren’t supported.
Can I send photos and open links?
Yes. The Light Phone II can’t show photos or open links on its own. Slight shows the photos people send you, sends yours as picture messages, group texts included, and opens links in your computer’s browser with a click.
What do I need?
Your Light Phone II and a USB cable for the first connection. The stable release needs a Mac with Apple silicon and macOS 13 or later. Intel Mac, Windows and Linux builds are previews.
Does Slight change my phone’s software?
Setup saves recovery files on your computer, then adds your computer’s key so the phone trusts it over USB. It doesn’t replace LightOS or the bootloader, and LightOS stays your default messaging app.
Does my phone have to stay in EDL mode?
No. EDL mode is only used during the initial USB setup. Slight restarts your phone into LightOS when setup finishes. You can then use your phone normally, make calls and send texts while Slight’s connector runs in the background.
Do I need to keep my phone plugged in?
No. After you pair once over USB, Slight connects over your local Wi‑Fi, or through an encrypted relay when your phone is on another network or cellular.
Can anyone read my messages on the relay?
No. Messages are encrypted between your computer and phone with a key that never goes to the relay. It sees only encrypted data, its size and timing.
How does Slight stay up to date?
Slight checks for new versions, verifies each update’s signature and installs it when you restart the app. You can turn automatic updates off in Settings.
Is there a Windows or Linux version?
Yes, as previews for 64-bit Intel/AMD computers. Intel Macs also have a preview. These builds have passed automated tests; phone setup and desktop integration still need checks on real hardware.
Is Slight made by Light?
No. Slight is an independent app and isn’t affiliated with or endorsed by Light.
