Gadget Box gives you three great tools in one app, with more to come over time.
1) A fully featured flashlight. This flashlight has an on/off button which can be locked so you don't accidentally turn it off in the dark. You can also push a button to get softer light using the front screen.
2) A magnifier which lets you zoom in on items so you can see them better. You can also turn the light on if it is in a dark area. Take a snapshot of what you are looking at for review later, great for serial numbers on the back of equipment.
3) A full functioning level.
Up to six family members will be able to use this app with Family Sharing enabled.
