VCL Checklist uses your photo or image to 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 Free version allows up to 10 checkmarks this gives you a chance to try the app and see if it fits your needs. Upgraded versions are 25 ,50 and 100 checkmarks.
