MacroStack 2.0.1

The first public release of MacroStack: a focus-bracketing camera for Android that stacks on the phone.

Install: download MacroStack.apk below on your phone (Android 10 or newer), open it, and allow "Install unknown apps" when Android asks.

• Shoot: set the nearest and farthest focus points and the number of frames; the app sweeps the focus in one fast burst (21 frames per second on a Galaxy S24 Ultra), with exposure and white balance locked. JPEG or RAW (DNG).
• Align: focus breathing, hand-held shift and tilt, and flickering light are corrected frame by frame.
• Stack: Depth map or Pyramid, in the background while you keep shooting.

Tested against focus-stack and Shine Stacker on 7 stacks: under 1% made-up detail on every one, and hand-held frames aligned to 0.06 px. Full results: https://macrostackapp.github.io/macrostack/#results

The engine is the same as 2.0. If you had a pre-release test build installed, uninstall it first: this release is signed with the project's permanent key, so Android won't install it over the old one.

Help improve the engine: share a focus stack. Everyone who helps is credited.
