Welcome to iComic, the premier application for reading comics on your iPhone or iPod Touch. iComic makes great use of the multi-touch function for simple and effective page navigation and zooming to provide the best portable comic book read you will find. iComic displays high resolution comic pages (jpg, tif, or png image files) contained inside compressed zip or cbz format archives. Using the built-in download function, comics can be downloaded from the internet or from a personal server and stored locally on your iPhone or iPod Touch. Your downloaded comics are stored on your device and so are always available for reading, even when you have no internet connection. As iTunes resizes images to a compressed format, iComic is also useful for displaying images for other uses e.g. maps, high detailed photos and ebooks (convert your pdf books to jpeg and you have a perfect reader for those large pdf files, normally unreadable due to the high memory requirement). iComic currently provides three methods for turning pages: swiping your finger on the screen; by taps in the screen corners using the Corner-Tap method; or by Multi-Touch (tap once to page forward, twice to page back). Zooming is by the familiar pinch method used in Safari and other applications or by double tapping the screen when in Corner-Tap mode. The application is very stable and can easily handle zip files up to 60MB with infrequent problems observed with files of much larger size. Individual image files inside the zip files are constrained to a maximum 3 million pixels (e.g. 3,000 pixels high x 1,000 pixels wide or equivalent) though for the sake of battery conservation much smaller sizes (~1000 pixels high) are generally used. A manual for setting up and using iComic can be downloaded from http://red.halfmoon.jp/AppStore_iComic_V1.3_FAQ.pdf The author of this application is Japanese so for excellent community support and discussion in English please visit the helpful and friendly ~*~ Ultimate icomic Thread ~*~ at www.ipodtouchfans.com/forums/showthread.php?t=23759

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.).
