• Added a Simplified Chinese interface. • New 3D eraser — wipe away parts of the volume with your finger to reveal hidden structures. • Even broader DICOM compatibility — more hospital and PACS exports open directly. • Stability and refinements.

• Compressed DICOM support — JPEG 2000, JPEG Lossless, RLE, and JPEG Baseline. Studies exported from most PACS now open directly. • Import a single DICOM file, or pick a whole folder — clearer Add menu. • Open studies shared as HTTP links. • Stability fixes and refinements.

New MPR mode — view all three planes (axial, sagittal, coronal) at once with a linked crosshair. Oblique reformatting, slab thickness, a ruler on every plane, anatomical orientation labels (R/L/A/P/H/F) and zoom sync. Stability and performance improvements.

• Import password-protected ZIP archives • Correct slice (MPR) reconstruction for studies acquired in any plane • Haptic feedback on button taps (can be turned off in Settings) • Smoother slice scrolling and brightness adjustment • Fully localized interface and messages (English / Russian) • Improved catalogue thumbnails and overall stability

• Groups (folders) in your study list — sort exams into your own folders, collapse them, reorder. • Sorting — by date added, examination date, type (CT/MRI/…) and body region. • Export 3D models as OBJ and STL — for 3D printing and viewing in other apps. • Body-region names are now localized (EN/RU). • 3D viewer: front view by default, pause-on-idle to save battery, and a clear message when there are too few slices to build a volume. • Cleaner, more informative study cards. • Minor UI and stability improvements.

• Fixed importing archives that contain non-Latin (e.g. Cyrillic) file names inside — discs and ZIP files from some clinics no longer fail with a "corrupted archive" error. • Added a "Report a problem" button: if a study won't open, you can send us a quick technical report (no images or personal data).

• Adaptive resolution in 3D: smooth rotation even on large CT scans — resolution drops only while you interact and snaps back to full detail when the model is still. • Quick render settings right in the 3D viewer (shadows, lighting, FPS target) — applied per study. • Volume quality now defaults to Maximum for crisper detail. • Interface and stability improvements.

New X-Ray rendering mode in the 3D viewer — switch between Volume and X-Ray to see dense bones with dental work and metal hardware highlighted, in a clinical CT-projection style. Series variants now show their full DICOM SeriesDescription (e.g. "Head 0.6 H80s · 432") so you can tell reconstructions apart at a glance. Cleaner 3D rendering: stochastic jitter removes the concentric "iso-density" banding artifacts that occasionally appeared on smooth bone surfaces. Portrait orientation is now locked — no more broken layout after an accidental device rotation.

What's New in 1.2.1 • RAR and 7z archive support added (in addition to ZIP), for both file import and cloud links (Google Drive, Dropbox, Yandex Disk). • 3D clipping planes: up to three at once, new compact tabbed UI, panel no longer obscures the volume. • 3D viewer: "1×" zoom-reset button moved to the bottom-left corner. • 2D viewer: zoom-out down to 50%; one finger now only adjusts brightness, two fingers pan the image. • OPTG: drag the panorama with one finger to shift the underlying arch — a corner thumbnail with the curve appears while pressed. • Fixed a crash at maximum zoom in the OPTG arch-drawing mode. • Various UI and stability improvements.

• Panoramic (OPTG) view — reconstruct a flat panoramic image of the dental arch from a CT scan, with adjustable slab thickness and a histogram window. • Sagittal and coronal slices (MPR) — in 2D mode you can now view your scan from the side and front, not just from above. • Density fine-tune — a histogram with two handles trims "extra tissue" out of the 3D model. • Clipping planes — slice off part of the 3D model along X/Y/Z to look inside. • Share an examination, or save a panorama image to Photos, via the system share sheet. • 3D quality switch in Settings for crisper side reconstructions. • Ruler and measurements in the side planes, with a magnifier for precise placement. • Fixes: Yandex.Disk import links and exam renaming.
