Displays x, y, and z component of magnetic field and inclination.Draws compass needle which shows orientation of the magnetic fieldin 3D.

Monitor skin changes such as suspicious moles, rashes, wounds, etc.You can take a photo of the spot, mark its position on the body andthen take a series of close-up photos of the same spot atsubsequent times. SkinMonitor uses objects of known size (e.g.coins) to calibrate the spot's dimensions and thus allows fordirect comparison of spot's close-up photos (the evolution of thespot). IMPORTANT: Please read the instructions inside the app toobtain the best results. Also, don't expect any numericalquantification of skin spots (like instant ABCDE evaluation whichis common in other skin apps), since it is useless and can onlyharm you. The evolution of a spot can have direct medicalimplications: - rapidly growing skin mole may be a sign ofmelanoma, a dangerous type of cancer - appearance and growth ofrashes might indicate food allergy - sudden change of a healingwound may be a sign of an infection
