EZViewer for ODB++

Open the ODB++ archive your CAM team sent you right on your phone or tablet — no laptop needed.
The fastest way to check a board on the assembly line, in a meeting or in the field.

■ Supported files
- ODB++ archives: .tgz / .tar.gz / .tar / .tar.Z / .zip (including a tgz inside a zip)
- ODB++ exported from Altium, Allegro, Xpedition, KiCad and more
- Opens the archive directly — no need to unpack it first.

■ View & inspect
- Toggle, recolor, reorder and solo individual layers
- Net highlight: long-press a pad or trace to light up the net.
- Find parts & nets: search by reference, part number, value or net name and jump straight to it.
- Tap info: tap a part, pin or feature to see reference, part number, package, net, symbol and attributes.
- Bottom view, quick layer views (top, bottom, copper, drill), board size, light background
- Measure pad, pin and via sizes and distances (mm, mil, inch …)
- Share the current view as PNG

■ Free version and Pro
These are Pro features in the free version. 2-layer boards are fully viewable for free.
- Inner copper layers (inner signal and plane layers) of 4-layer and larger boards
- BOM & assembly mode
- Switching steps and viewing step-repeat panels — the free version shows only each board's outline on a panel.
- The drill table in design info
- Measurement values are shown for the first 5 measurements.
- Sharing as PDF is a Pro feature (PNG sharing is free).
- A small Pro banner sits at the bottom of the screen.
A one-time in-app purchase (not a subscription) removes every limit and the banner, and can be restored on any device with the same Google account.

■ Fast and private
- Opens large jobs with millions of features. Documentation layers load only when you turn them on.
- Works completely offline. Your files never leave your device.

Try it right away with the built-in sample (6-layer board, 2×2 panel). On the sample, inner layers, BOM & assembly mode, steps & panels and the drill table are free to try.
