Installation notes

Android — enabling sideload
  1. Tap the downloaded truepost-latest.apk in your notification shade or Files app.
  2. If prompted: Settings → Apps → Special app access → Install unknown apps → allow your browser or Files app.
  3. Tap Install. Done.
iOS — TestFlight or ad-hoc
  1. For TestFlight (recommended): accept the invite link sent by the Truepost team. Install via the TestFlight app.
  2. For ad-hoc IPA: your device UDID must be registered. Install via Apple Configurator 2 or AltStore. Contact joe@truepost.com to register.
Linux — AppImage (recommended)
  1. Download Truepost-latest-x86_64.AppImage.
  2. Make it executable: chmod +x Truepost-latest-x86_64.AppImage
  3. Run it: ./Truepost-latest-x86_64.AppImage
  4. No installation required — works on any x64 Linux distro.
Linux — .deb (Ubuntu, Debian, Mint, Pop!_OS)
  1. Download truepost_latest_amd64.deb.
  2. Install: sudo dpkg -i truepost_latest_amd64.deb
  3. Fix any missing deps: sudo apt-get install -f
  4. Launch from your app menu or run truepost in a terminal.
Linux — Flatpak (any distro with Flatpak installed)
  1. Download truepost-latest.flatpak.
  2. Install: flatpak install truepost-latest.flatpak
  3. Run: flatpak run com.truepost.Truepost
  4. Or launch from your app menu — it integrates automatically.
Linux — ZIP (manual / any distro)
  1. Extract: unzip truepost-linux-latest.zip -d truepost
  2. Make executable: chmod +x truepost/trueposter
  3. Run: ./truepost/trueposter
  4. Optional: create a .desktop launcher pointing to the binary.
macOS — bypassing Gatekeeper
  1. Open the DMG and drag Truepost to Applications.
  2. On first launch macOS will block the app because it is not from the App Store. Right-click the app icon → Open to bypass this once.
  3. Alternatively: xattr -d com.apple.quarantine /Applications/Truepost.app
