Version 1.3 · 2026-09-02
Fixes to RAW support: Trevni now supports RAW files from cameras, DNG, and ProRAW from iPhone. Your negative is processed at full resolution, preserving much more detail for conversion and editing. Full-resolution export: Save your finished positive as JPEG, HEIC, or TIFF. TIFF keeps every pixel for further editing; JPEG and HEIC are better for sharing. Your photo’s details come with it: Camera, lens, exposure settings, date, and location carry across to the saved image, so an inverted frame stays as easy to find in your library as the original. Smoother to use: Sampling the film base and moving the adjustment sliders are noticeably more responsive, especially on large files.

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
