← Dashhound · Rewind

Build it yourself.

No App Store yet — but you can install it in about 45 minutes, for free, with a Mac and your iPhone. No coding needed.

Dashhound is experimental software, provided as is. It may fail to save a clip. It is not a safety device and does not replace a certified dashcam. You are responsible for using it lawfully where you live.

What you need

The free Apple account signs the app for 7 days. After that, plug the iPhone in and press Run again — 2 minutes. Apple's rule, not ours.

Two ways to install

A · Let an AI do it

Recommended if you have Claude Code, Claude Cowork or ChatGPT on your Mac

Paste this prompt. It reads the install guide from the repo, checks your Mac, installs what's missing, builds the app and tells you when it's your turn (sign in, plug the phone, tap Allow). It never types your Apple password — you do.

You are helping me install Dashhound · Rewind, an open-source iOS app for smart glasses, on my own iPhone from source. I am not a developer.

Repo: https://github.com/jsala1 — read README.md and INSTALL.md first and follow them; they are the source of truth. If anything below conflicts with them, the repo wins.

Rules:
- Work step by step and tell me what you are doing in plain language.
- Check my Mac first (macOS version, free disk space, whether Xcode and the command line tools are installed) and install only what is missing. Ask before any download over 1 GB.
- Never type or ask for my Apple ID password, two-factor codes or any password. When a step needs me (signing in to Xcode, plugging in the iPhone, tapping "Trust" or "Allow" on the phone, enabling Developer Mode on the phone or in the Meta AI app), stop, tell me exactly what to do, and wait.
- Change the bundle identifier to a unique one based on my name before building, and leave MetaAppID empty as INSTALL.md says.
- When the app is running on my phone, walk me through the first launch and one test: double tap the temple, then check Photos.
- If something fails twice, don't loop: summarize the error in one paragraph I can paste into a GitHub issue at https://github.com/jsala1/issues/new?template=install.yml

Start by checking my Mac and telling me the plan in 5 lines.

B · Do it yourself, step by step

Ten steps, each with a way to check it worked.

Checklist

  1. 01
    20–30 min

    Get Xcode from the Mac App Store — it's a 20–30 minute download. Open Xcode once, accept the license, let it install its components (~10 min).

    Xcode on the Mac App Store ↗

    How you know it worked: Xcode opens and offers to install components.

  2. 02
    2 min

    Plug the iPhone into the Mac with Xcode open (unlock the phone, tap Trust). Then on the phone: Settings › Privacy & Security › Developer Mode › on. The switch only appears after the Mac has connected once.

    How you know it worked: the phone restarts and the switch is on.

  3. 03
    2 min

    Settings › App Info › tap the version number 5 times. If you don't see it, look under Settings › Your glasses › Developer Mode. If the app says your glasses need an update, do it in Meta AI › Devices first.

    How you know it worked: a "Developer Mode" toggle appears.

  4. 04
    1 min

    On GitHub, green "Code" button › Download ZIP (or git clone if you know it).

    Open the repo ↗

    How you know it worked: a folder named dashhound-main on your Mac.

  5. 05
    2 min

    Open the folder and double-click Dashhound.xcodeproj.

    Read INSTALL.md ↗

    How you know it worked: Xcode opens the project with no red errors.

    2 min

    In Xcode: Settings › Accounts › + › Apple ID, sign in. Then click the project name at the top left › Signing & Capabilities › Team › choose "Your name (Personal Team)".

    How you know it worked: no red text under Signing.

  7. 07
    1 min

    Change the Bundle Identifier to something unique, e.g. com.yourname.dashhound. Same screen, Bundle Identifier field.

    How you know it worked: Signing turns green.

  8. 08
    5 min

    iPhone plugged in and unlocked, choose it in the top bar, press ▶ Run. The first time takes a few minutes ("Preparing iPhone"). If the phone says Untrusted Developer: Settings › General › VPN & Device Management › your Apple ID › Trust, then press Run again.

    How you know it worked: Dashhound opens on the phone.

  9. 09
    3 min

    The app sends you to Meta AI to register and allow the camera; come back.

    How you know it worked: "Looking for your glasses…" then "Watching".

  10. 10
    1 min

    Glasses on. Tap Start dashcam, wait for "Watching". Double tap the temple → "Saved!" → the clip is in Photos. Bluetooth music pauses during the test — normal.
