This update fixes Pro purchasing and makes backups faster and more reliable. • Fixed: the Sync Shutter Pro upgrade can now be purchased (previously failed with "product not found") • No more duplicate photos when re-importing the same card to your Photos Library • Large video uploads use a fraction of the memory and no longer stall on iPhone • Live Activity now shows real-time progress during imports (iOS) • Mac: custom backup folders (Google Drive, OneDrive, Dropbox, Lightroom) stay connected after relaunch • Smarter retries when a cloud service rate-limits or the network drops • Clearer error messages when a signin expires • Security hardening and many smaller fixes

Sync Shutter Pro is now on iPhone and iPad — one purchase unlocks every device. • S3-compatible backup (Pro): import straight to your Synology NAS, Backblaze B2, MinIO, or any S3 endpoint • Checksum verification: every file saved to the Files app is verified byte-for-byte against the original • Custom file naming templates (Pro) and RAW+JPEG pair control (Pro) • Redesigned for iPad with sidebar navigation • Fixed: the home screen widget now installs correctly on iOS 17 and later

- Premium UI refresh across the app - Bug fixes and performance improvements

Reliability improvements for SD card backups. Sync Shutter now correctly detects cards that use lowercase folder names (common on FAT32-formatted cards), surfaces a clear warning if all file types are disabled before scanning, and resolves several rare crashes that could occur during upload.

Redesigned History A new dashboard shows your backup stats at a glance — files backed up, total data protected, sessions, average per session, favorite card, and time spent. Filter by the last 7 days, 30 days, or all time. Destination usage shows how often each backup location has been used with a visual breakdown. Smarter Settings Backup settings now explain themselves inline — no more hunting for what each toggle does. File type sections show supported extensions directly. "Skip files already backed up" now lives in General settings More Reliable Backups Fixed three edge cases in the backup pipeline that could cause files to be re-copied unnecessarily or silently skipped across multiple destinations. Integrity verification now correctly re-copies a file if the destination copy is corrupt.

Integrity verification. After each backup, Sync Shutter now optionally verifies every file using a SHA-256 checksum. If a copy is corrupted, it's detected, removed, and flagged — so you're never left with a silent bad backup. Smooth progress on large files. The progress ring no longer stalls while copying big RAW files or videos. Progress now updates continuously as data moves. Cloud retry when offline. If your cloud destinations are unreachable mid-backup, the pending uploads are queued and retried automatically when your connection returns. Redesigned History dashboard. Backup history is now a summary view with stat tiles, per-destination usage bars, and a 7-day/30-day/all-time range picker. Reliability fixes. Fixed three edge cases in the backup pipeline: multi-destination history records could corrupt each other's stored file size; incremental skip with checksums enabled could silently accept a same-size but content-different file; files in certain path layouts could land at the wrong destination path.
