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.

Foto Notes burns the date, time, street address, GPS coordinates, compass, altitude, a small map, the weather and your note right into your photos. There is nothing to edit afterwards and no separate notebook. Construction site, apartment viewing, handover, inspection or survey: the photo shows when and where it was taken, and the details stay on every copy. THE DOCUMENTATION STAMP An info card that updates live in the viewfinder: - Large clock with seconds, date and time zone - Full street address with street, number and city - Exact GPS coordinates, altitude and compass direction (true or magnetic north) - A map thumbnail of your position, standard or satellite (Pro) - The weather at capture: temperature, wind and humidity (Pro) - Your note - Your logo, company name and website (Pro) Hold the stamp to show or hide each element. What you see in the viewfinder is exactly what gets burned in. DESIGN RIGHT IN THE CAMERA Change transparency, colors and placement in the adjust panel next to the shutter, and the viewfinder shows each change instantly. The stamp sits in a corner or above/below the photo, so it never covers a detail. Stamp size: small, medium or large. VIDEO WITH A TIMESTAMP (NEW, PRO) In video mode the stamp is burned live into every frame. The clock keeps running, and the compass and map dot follow your movement. Records in Full HD with optional sound and saves straight to your photo library. SIX TAGS FOR YOUR NOTE Tap a tag and it drops into your note as a badge: - Date: today's date in the format you choose - Time: the current time, to the second - Location: city, country or full street address - Room: an entry from your room list (kitchen, bathroom, office …) - Coordinates: exact GPS position, even offline - Company: your company name and website (Pro) MADE FOR VIEWINGS AND JOB SITES Pick the room before each shot, from the built-in list or, with Pro, from your own. Three viewings later you still know which bathroom belongs to which apartment. On the job site, date, coordinates and map record every step. CHECK-IN: WORK HOURS WITH PROOF Check-in mode clocks you in and out with a proof photo from the selfie camera, with the time burned into it. The app reminds you to check out, times you add or correct later are marked in the report, and iCloud backup keeps your time log through a reinstall. Export the work time report as a PDF with photos, daily totals and signature lines, or as CSV. Your first report is free, after that it is part of Pro. STAMP PHOTOS YOU ALREADY HAVE (PRO) Stamp existing photos from your library or the Files app. Date, time and location come from the original's capture data (EXIF), and the originals stay untouched. TRY EVERYTHING FIRST Your first 3 photos after installing carry the full Pro stamp, including the map and your own branding. Then you decide what to keep. NO ADS The free version takes unlimited photos and shows no ads. In return it carries a small Foto Notes badge inside the stamp. FOTO NOTES PRO Pro replaces that badge with your logo, company name and website on every photo you hand to clients, insurers or contractors. It adds video mode, the map thumbnail and stamp layouts above/below the photo. Get Pro as a subscription or as a one-time lifetime purchase, which launches at an introductory price. ALSO ON BOARD - Quick zoom presets, flash, continuous light and front camera - Flexible date, time and location formats - Save photos to your photo library or your own iCloud Drive PRIVACY The app uses the camera, microphone and location only to take the photo or video and render the stamp. Your photos stay on your device or in your own iCloud Drive and are never sent to us or anyone else. The app needs no account and does not track you.
