Read full description

This is a clock for all: - for users aiming visual pleasing clock faces - for visual impaired users reading the time with better contrasts - for blind users hearing the speech synthesizer time message in their language - for children learning to read the clock - for children and adults having fun to select a clock’s face with random colors - for all users preferring apps easy to use and designed for all Thus it is a powerful clock in the sense of:  „Technology is most powerful when it empowers everyone“ (cited from www.apple.com/accessibility). The clock4all app provides 10 different clock faces. And one extra large digital time display. Alarm time can be set. The clock indicates low battery levels with a color index. Your questions may be: 1. Must I fumble with menus, settings and modes? No. This clock app is designed for simple and robust use. You will not have to make settings in menus. There are no menus, no buttons, no sliders. Because blind, partly sighed or elderly users can hardly deal with them. 2. How does it work then, to interact with this app? There are only three interactions: - You touch the display and a voice will speak out the time in your language. - You swipe over the display and the clock face will change its design. - You shake the device and a prompt appear to set the alarm time. 3. How do the app know about the language I prefer? The app simply uses the selected language of your iPad or iPhone. 4. Can I hear the voice speaking out the time in different languages? Just go to your general iPad/iPhone settings of „Language & Region“ and change the language and its region. 5. Which languages/nations are supported by this app? USA/England, Spain, French, Italy, Germany, Netherlands, Ireland, Czech Republic, Hungary, China. Japan, Korea. 6. My language is not supported yet. Do you plan to update for it? Yes, of course, it is a clock4all. Get in contact with the author: juergen.held@hfg-gmuend.de Explain how to spell the time in your language for to update the app. 7. Does the clock4all app supports different display sizes? Yes all displays are supported. The clock’s faces will be presented at best readable sizes. 8. Can I use the clock4all in portrait and landscape orientation? Yes, the clock will rotate if you rotate your iPad or iPhone device. 9. How will the clock tell about low battery levels? Less 10% battery capacity will trigger the clocks face to have blue colored markers. Less 5% battery and the markers became red colored. If you tap then to hear the time message, the voice will append: "Battery level is less x%".

Turn coordinates into your route. DotTrail is a route-file editor by LocationLab for iPhone and iPad. No app account is required. • Import and export GPX, KML, GeoJSON and CSV. • Recognize decimal, DDM and DMS coordinates in mixed text, then preview and create a straight-line route. • Connect points in order; select, drag, rename, reorder and delete them on the map or in the list. • Draw a polygon to preview and remove points inside it. • Route Tools: add loops around selected points, use fixed or ranged offsets, and build circular detours. • Smart Organize: shorten a trip, optionally keep the end, return to the start, merge nearby points, or renumber names with a prefix. • Preview the original and adjusted routes with point counts and distance comparisons before applying. • Undo and redo, restore three recent saved versions, and recover deleted routes. • Save and reopen projects, export repeatedly, and back up the original import and history. • Sync with iCloud between devices using the same Apple Account. English and Traditional Chinese follow your system language. Free download with a bottom banner ad; no subscriptions or in-app purchases. Routes use straight lines and do not provide road navigation. Smart sorting uses straight-line distances, does not consider roads or obstacles, and does not guarantee a mathematically shortest route. Smart sorting supports up to 2,000 points; imports support up to 25 MB and 20,000 points. Multiple routes are combined in file order. GPX waypoints take priority over route data. Conversion retains supported fields; other original content remains available in a full project backup.
