VCL Checklist 100 uses your photo, map or image from Photos on your iPhone/iPad these can be of any size. You can place colored Circles (check marks) anywhere on the image. The Circles change colors when you touch them showing that you have inspected that area. You can load in any drawing or image and place colored circles at different points on the drawing/image that should be checked. For example: You need to check Exit lights or fire extinguishers each month or a preflight for an airplane. Load in a floor plan image or any image and place circles at all Exit lights, fire extinguishers or other areas to be checked. The circles are all yellow when unchecked, then when you need to check each Exit light or fire extinguisher just touch the yellow circle and it will turn blue showing that you have checked it. The app remembers which one you have checked. You can reset the blue circles to yellow at any time. The Information screen shows all circles that have been checked, you can add information for each circle, fire extinguisher, exit light or other information. This can also be printed. This version (VCL Checklist 100) allows up to 100 checkmarks. An Upgraded versions is 100 checkmarks. If a building is large you can use VCLChecklist 100 for lights, VCL Checklist 50 for Fire extinguishers, and VCL Checklist 25 for other areas to be checked.
