The outward engine milestone — the instrument is fully playable:
Outward scan from a scan line that grows in both directions
Drag the line to reposition, two-finger twist to rotate — mid-scan
Classic vs Outward mode; Mirrored vs Split source
Linked / independent front speeds; angled lines
Scan / Reset, live progress
Saving stills & recording video are wired internally but their buttons land in the next build — I’ll refresh this link when they’re on screen.
Worth trying
An outward scan on slow, continuous movement (smooth flowing streaks) vs an abrupt cut (hard seam)
Split mode: the two halves should sample genuinely different sides of the scene, not mirror each other
Twist the line mid-scan — the fronts jump to the far edge of what’s written (that’s the no-rewrite guarantee; wedge-fill & smooth options are coming in M4)
Installing
Tap Download APK above.
Open it from the download notification or Files.
Android asks to allow installs from this app the first time — grant it, then Install.
Play Protect may warn about a sideloaded app — expected for a debug build; choose “install anyway”.
Grant the camera permission on first launch. The app is fully local — camera only, no network, nothing leaves the phone.
