Da habt ihr gute Arbeit geleistet. Die App ist viel schneller und besser als unsere Kameras. Dabei kann sie mehr von den Funktionen her. Finde ich klasse!

Release history

What changed in recent updates

1.706Zoom fix: natural perspective, no distortion

Camera now starts at 1.0× (main lens) by default instead of ultra-wide – preview and photo match the natural eye perspective again
Removed the previous automatic ultra-wide (0.5×) startup in normal mode, which caused distant-looking, slightly distorted shots
Macro mode still zooms in as before

1.705PDF report generator, TrueQ integration & new gallery

On-device PDF report generator: photos, timestamps, GPS, voice notes, and SHA-256 checksums per code – optionally with the original photos embedded as a ZIP attachment
Native TrueQ integration as an upload target alongside standard FTP, including optional auto-upload on new code
Enhanced macro mode with visual feedback, configurable voice workflow right after capture
New, clearer camera settings menu; the code input row turns 60% transparent once a code is recognized, for an unobstructed view of the subject
Smarter gallery: search/filter by code and date, double-tap or two-finger zoom, dedicated back button
Left-handed mode: controls can be mirrored for better ergonomics
Full Android 15 & Java 17 support, R8 obfuscation for a smaller, more secure app package

1.704Smooth screen rotation & stability

Landscape photos are now saved correctly in every orientation – even with the device rotated 180°
Completely rebuilt rotation logic: the camera keeps running uninterrupted while rotating, controls reposition without delay (optimized for the S25 Ultra)
FTP optimization: longer timeouts and larger buffers for more stable transfers on weak signal
Various R8/ProGuard and voice-related fixes (including a bug where language switching could block system screen rotation)

1.703Auto-upload folder control & Android 16

New checkbox: upload images flat or into code-named subfolders
compileSdk/targetSdk raised to 36 – already meets Google Play requirements for November 2026
All upload settings now persist across app restarts

1.702Auto-upload on new code

Automatic FTP upload when switching to the next code
Retry mechanism and automatic reconnection on connection loss
Standard FTP only, not available for TrueQ

1.70New in-app gallery

RecyclerView with Glide integration for smooth scrolling
Swipe navigation, smart EXIF toast, real-time search and sorting

1.607–1.609Evidence security & stability

SHA-256 checksums embedded directly in EXIF
New FTP/SSL system (Apache Commons Net), FTPES/FTPS
TrueQ API integration, intelligent macro mode, professional splash screen
