TurtleBackup vs Contactidy

Easily backup files from memory cards to external drive (like USB flash drive) or to internal storage. Combined with a compatible USB hub / card reader, it’s a simple and lightweight photo backup solution for travel / short trips.  Has 4 main features: Check, Backup, Integrity check, History.  "Check" gives a brief overview / size estimate, and also confirms whether basic conditions (e.g. available space) are met.  "Backup" copies files from source to destination. You have 3 options regarding folder structure on destination: • use original (same as source) folder structure • group files into folders by file creation date (YYYY-MM-DD, example: 2026-02-10/DSC_5555.JPG) or • group files by file creation date and type (YYYY-MM-DD/type, example: 2026-02-10/JPG/DSC_5555.JPG) There's also a filter feature - you can exclude files created before certain date (e.g. if you want to skip files created before the trip, but don't want to delete them from source). Incremental backup is supported as well - matching existing files are skipped, if size (and file creation time, depending on selected setting) is the same. Also, if you're using same backup source / destination each time, app will remember and pre-select them on startup, so in ideal scenario, backup can be performed just by clicking couple of buttons. "Integrity check" is optional, compares checksums of corresponding files from source folder to the ones in the destination folder. "History" is optional (can be enabled via settings) - saves (locally) basic statistics (date, number of files, etc.) about performed backups, which you can review later. App doesn't need a network connection and does not support backup to network locations (cloud etc.).

Contactidy helps you rename all your contacts quickly. Pick a name style (e.g. First Last) and apply it to your whole address book. Everything is processed locally, no data is collected. Great for keeping your contact list clean and organized.
