This app is suitable for calendars according to the ICS standard RFC 5545/5546,  which is used by most computer programs.  This is the prerequisite, so that you can also use your calendar from the PC  with Outlook, Lighting or other software. This calendar inherits the following functions: - Date Overview    All appointments are displayed time-dependent. The list can be searched. The list is kept on the iPhone and can be stored and loaded externally. Appointments can also be transferred from the iPhone - Monthly Overview    Monthly overview helps navigate through calendar dates quickly.  Appointments additional are listed separately.  An overview of appointments of the day couldt be called up on the screen. - Date    Appointments can include date and time or just the date.    These can be stored with or without time zone. So, for example    the date New Year should be used without time zone as the year    actually begins on earth at different times.    In contrast, a birthday with the time zone should be deposited, in    which the jubilarian lives. Thus, at the time of congratulation    nothing goes wrong. - Series date    One-off and serial appointments can be generated.    A recurring event is controlled by a rule by which the repetitive    appointments are generated. These rules fulfill the standard.    So you do not have to dive deeper into the rules, as most common rules could be created by key combination.

A complete PDF editor that runs entirely on your device. No account and no sign-in. The app ships without network access at all, so nothing you open can be uploaded — not by us, not by anyone. Nothing it produces is branded or stamped. EDIT WHAT IS ALREADY THERE • Change words in an existing PDF. Tap a line, retype it, and the layout stays where it was. • Fill in forms, or type anywhere on a printed form that has no fields. • Sign by drawing or typing. Your signature stays in this app's own storage on this device, is left out of backups, and never leaves it. SCAN AND READ PAPER • Photograph pages with edge detection, auto-capture, perspective correction and shadow removal. • Read the text on a photographed page, then copy it, export it, or retype a line in place. • Make a scan searchable by adding an invisible text layer — the page still looks exactly the same. PAGES AND FILES • Reorder, rotate, delete, duplicate, insert and extract pages by dragging. • Correct page orientation: one page at a time, at full size, or turn a whole document at once. • Combine several PDFs, choosing which file goes first and rearranging pages afterwards. • Split a document, export pages as images, or export the text as a Word file. • Compress by re-encoding oversized images only — text and drawings are left untouched, so the file stays sharp and searchable. MARK UP AND PROTECT • Draw, highlight, underline, strike through, add notes, shapes and text boxes. • Redact properly. The content is removed from the file, not hidden under a black box that copy-and-paste defeats. • Add your own watermark — text or an image, tiled, centred or dragged anywhere. BUILT TO BE HONEST • Your changes are written to a draft as you work, so a crash loses nothing. • Undo and redo everything, including page changes. • Saving asks before it overwrites, and validates the file before it replaces yours. • Where a tool has a limit worth knowing, the app says so in the app — not after it has cost you something. WHAT THIS APP DOES NOT DO It does not convert to Word or Excel with the original layout. Doing that faithfully needs a server, and this app has no network access. It exports the document's text instead, and says so before you use it.
